149-656: The San Diego Trolley is a light rail system serving San Diego County, California , United States. The trolley's operator, San Diego Trolley, Inc. ( reporting mark SDTI ), is a subsidiary of the San Diego Metropolitan Transit System (MTS). The trolley operates as a critical component of MTS, with connections to and integrated travel tickets with the local bus systems. The trolley system serves 62 stations , over about 67.9 miles (109.3 km) of route, using four primary lines ( Blue , Green , Orange , and Copper ) that operate daily, and

298-470: A "downtown loop" heritage streetcar line ( Silver ) that operates on holidays. There is one downtown station where all the lines connect, and 13 other stations that provide transfers to a second line (two of these also provide connections to commuter rail systems). The trolley began service on July 26, 1981, making it the oldest of the second-generation light rail systems in the United States, and

447-724: A "light rail" vehicle (it is a heavy rail vehicle), and is only included for comparison purposes. Low-floor LRVs have the advantage of a low-floor design, allowing them to load passengers directly from low-rise platforms that can be little more than raised curbs. High-floor light rail systems also exist, featuring larger stations. Historically, the track gauge has had considerable variations, with narrow gauge common in many early systems. However, most light rail systems are now standard gauge . Older standard-gauge vehicles could not negotiate sharp turns as easily as narrow-gauge ones, but modern light rail systems achieve tighter turning radii by using articulated cars . An important advantage of

596-512: A broad swath of land, as do many government-owned conversation areas. Some public rights-of-way are negotiated with government as a part of property development. This can result in a public-use right of way, such as an urban waterfront walkway, the public right to use a lobby as a shortcut during business hours, or public access to recreational land such as an urban park (which may include activities not limited to simply passing through). In England and Wales under current law, public access to rivers

745-458: A bus, there will be even more capacity when there is a combination of cars and light rail. Table 3 shows an example of peak passenger capacity. The cost of light rail construction varies widely, largely depending on the amount of tunneling and elevated structures required. A survey of North American light rail projects shows that costs of most LRT systems range from $ 15 million to over $ 100 million per mile. Seattle's new light rail system

894-441: A certain number of years without obstruction by the property owner. Changes to circumstances (such as construction of a new road that connects to the dominant estate), disuse, and obstruction by the property owner may affect this type of right. In other geographic situations, several neighbors will agree to maintain (or inherit from the original developer) a private road that connects their properties, either as communally owned or as

1043-403: A chaotic breakdown inflow and a dramatic drop in speed (a traffic jam ) if they exceed about 2,000 vehicles per hour per lane (each car roughly two seconds behind another). Since most people who drive to work or on business trips do so alone, studies show that the average car occupancy on many roads carrying commuters is only about 1.5 people per car during the high-demand rush hour periods of

1192-1142: A common right-of-way (however, Link converted to full separation in 2019). Some systems, such as the AirTrain JFK in New York City, the DLR in London, and Kelana Jaya Line in Kuala Lumpur , have dispensed with the need for an operator. The Vancouver SkyTrain was an early adopter of driverless vehicles, while the Toronto Scarborough rapid transit operated the same trains as Vancouver, but used drivers. In most discussions and comparisons, these specialized systems are generally not considered light rail but as light metro systems. Around Karlsruhe , Kassel , and Saarbrücken in Germany, dual-voltage light rail trains partly use mainline railroad tracks, sharing these tracks with heavy rail trains. In

1341-414: A concession) are known as in gross and are typically created by arrangement. Right-of-way easements that benefit the general public are often created for foot, bridle, mountain bike, and ATV paths (often carrying a mix of users). These routes are all formally highways, but have legally restricted modes of use. Such rights-of-way might extend a recreational trail network from land owned by the government or

1490-418: A contractual, appurtenant easement. Private ownership typically gives the owners more power, such as the right to restrict parking to owners and their guests. Traffic laws (such as obeying speed limits and stop signs) typically still apply to private roads if they are open to the general public. Transferrable easements (such as the right to use a specific boat ramp not used by the property owner or operate it as

1639-423: A conversation non-profit, to connect trails to public roads, to make long-distance trails , or provide access to a beach or waterfront. Especially in common law jurisdictions, these can be created by longstanding use, also known as easement by prescription . They can also be purchased or by a government or conservation group or created by eminent domain. Property owners can also explicitly grant permission to use

1788-451: A formal process of voluntary discontinuation or abandonment, often involving public comment. This allows the government to clarify which facilities it will and will not spend money to maintain, which can affect property owners and values. It also clearly distinguishes between transportation facilities which are temporarily not being used versus those which are permanently out of use, and provides for orderly transfer of rights. When an easement

1937-418: A general easement to access certain areas when necessary to construct and maintain their networks. In many cases they must request permission from the owner to expand or perform construction activities on a government or private right-of-way. When a road, railroad, or canal is no longer needed, the effect on property rights depends on the jurisdiction and how the right of way was created. Many jurisdictions have

2086-552: A guideway transit system. The entire process was assigned to MTDB to assure accountability. The legislation was written and supported by State Senator James R. Mills , the President Pro Tem during this period and a strong transit advocate. The MTDB formally started operations on January 1, 1976. The MTDB's enabling legislation and principles adopted by the Board required the planning give added weight to systems that satisfy

2235-416: A light rail train may have three to four cars of much larger capacity in one train under the control of one driver, or no driver at all in fully automated systems, increasing the labor costs of BRT systems compared to LRT systems. BRT systems are also usually less fuel-efficient as they use non-electrified vehicles. The peak passenger capacity per lane per hour depends on which types of vehicles are allowed on

2384-627: A line that traveled between downtown San Diego, San Ysidro, northern Baja California (in Mexico), and Imperial County before connecting with the rest of the SP system in Plaster City, California . The hurricane caused $ 1.3 million worth of damage to the line ($ 6.96 million adjusted for inflation), primarily in Imperial County, east of San Diego. Freight service was suspended, and in light of

2533-435: A live rail. In outer areas, the trams switch to conventional overhead wires . The Bordeaux power system costs about three times as much as a conventional overhead wire system and took 24 months to achieve acceptable levels of reliability, requiring the replacement of all the main cables and power supplies. Operating and maintenance costs of the innovative power system still remain high. However, despite numerous service outages,

2682-543: A longer distance. Light rail cars are often coupled into multiple units of two to four cars. Light rail systems may also exhibit attributes of heavy rail systems, including having downtown subways, as in San Francisco and Seattle . Light rail is designed to address a gap in interurban transportation between heavy rail and bus services, carrying high passenger numbers more quickly than local buses and more cheaply than heavy rail. It serves corridors in which heavy rail

2831-642: A more diverse range of design characteristics than LRT, depending on the demand and constraints that exist, and BRT using dedicated lanes can have a theoretical capacity of over 30,000 passengers per hour per direction (for example, the Guangzhou Bus Rapid Transit system operates up to 350 buses per hour per direction). For the effective operation of a bus or BRT system, buses must have priority at traffic lights and have their dedicated lanes, especially as bus frequencies exceed 30 buses per hour per direction. The higher theoretical of BRT relates to

2980-517: A new signalling system that would allow two freight trains to operate at night, rather than one. To enable the switch to a low-floor light rail vehicle (LRV) fleet, platforms at 35 stations would need to be raised from either ground level or sidewalk level (4-inch (102 mm)) to 6-inch (152 mm). Stations also needed a new "safety edge tile" with a smooth surface in the center to allow wheelchair ramps to deploy (the existing safety tile would stop ramps from fully deploying). The other complication of

3129-456: A number of criteria: priority consideration for technologies available and in use, a system that is capable of being brought into operation incrementally, and using rights-of-way owned by public entities to minimize construction costs. In December 1976, the MTDB launched its 18-month Guideway Planning Project to be held in two phases. Phase 1 involved the evaluation of potential corridors based on

3278-457: A permanent public easement. Some jurisdictions legally recognize the right to roam —to move through any undeveloped land unless otherwise posted or fenced. This allows wandering beyond established trails. Even without a general the right to roam, not all rights-of-way have a physical indication of boundaries, and some easements do not specify any particular path to be taken when crossing. Some easements permit certain recreational activities across

3427-559: A popular destination for foreign tourists in the city. Traditional rights of way take the form of servitude de passage (right of passage) and droit de marche-pied (right to walk, along canals and canalised rivers). There is a system of about 120,000 kilometres of well-marked footpaths in France. Many were formerly the main routes between villages and are often "steeper and more direct than modern roads". There are also, in addition, sentier de grande randonnée , long distance trails . In

3576-420: A public way is over the private property of a single neighbor. In these cases, the owner of the "servient" estate (which is the one being crossed) may simply give permission, or the "dominant" estate (the one needing access) may purchase the easement, for example to construct a driveway. Such easements are attached to the dominant estate, or appurtenant . The dominant estate cannot sell the easement separately from

3725-407: A result, has many of the operating characteristics of a metro system rather than a light rail system. A capacity of 1,350 passengers per train is more similar to the heavy rail than light rail. Bus rapid transit (BRT) is an alternative to LRT and many planning studies undertake a comparison of each mode when considering appropriate investments in transit corridor development. BRT systems can exhibit

3874-401: A route, either through a deed restriction or informal means such as posted signs, and may place restrictions on times or types of traffic allowed. Whether this permission can be revoked or expire from disuse depends considerably on the legal jurisdiction, how it was granted, and the circumstances of public use. Some of these " permissive paths " are closed once a year to prevent the creation of

4023-740: A second line on March 23, 1986, that shared the same downtown tracks and traveled east to Euclid Avenue on the La Mesa Branch of the SD&;AE. The new route was then called the Euclid Line (part of today's Orange Line ). This line was extended to El Cajon by June 23, 1989, at which time it was renamed the East Line. Service was expanded beyond the old SD&AE right-of-way when the line was extended further, north, to Santee on August 26, 1995. The East Line's Bayside Connection extension to

4172-534: A top speed of 55–71.5 miles per hour (88.51–115.1 km/h) depending on the system, while the trains on the all-underground Montreal Metro can only reach a top speed of 72 kilometres per hour (44.74 mph). LACMTA light rail vehicles have higher top and average speeds than Montreal Metro or New York City Subway trains. Many light rail systems—even fairly old ones—have a combination of both on- and off-road sections. In some countries (especially in Europe), only

4321-418: A tramway, a light metro, and, in a narrow sense, rapid transit. This is especially common in the United States, where there is not a popularly perceived distinction between these different types of urban rail systems. The development of technology for low-floor and catenary-free trams facilitates the construction of such mixed systems with only short and shallow underground sections below critical intersections as

4470-412: A user to claim a right of way after 12 years of use across private land owned by another, 30 years on state land and 60 years on the foreshore . The claimant must apply to the courts, and have their claim confirmed by a court order, and then have it duly registered on the title deeds, a lengthy process. The user must prove "enjoyment without force, without secrecy and without the oral or written consent of

4619-530: A week. Limited service on particular segments is provided before 5 am and after 11:30 pm. There is no rail service between 2 am and 4 am. During these hours when there is no passenger service, freight trains of the San Diego and Imperial Valley Railroad operate on the trolley's right of way. Generally, trains operate every 15 minutes, seven days a week, with less frequent service during early morning and late evening hours. Additional service on

4768-470: Is a generic international English phrase for types of rail systems using modern streetcars/trams, which means more or less the same thing throughout the English-speaking world . Light rail systems can range from trams runnig in streets along with other traffic, to semi-metro systems having portions of grade separated track. People movers are even "lighter", in terms of capacity. Monorail

4917-446: Is a legal maneuver that avoids full abandonment, preserving a railroad easement for future reactivation without reverting property rights to real estate owners. Rail trails are often constructed on rights-of-way that no longer host active railroads, putting the property to productive use while preventing obstructions like buildings or crossing infrastructure from being built. These may be used for recreation or for bicycle commuting, given

5066-403: Is a right to cross that does not include full ownership of the land. For example, the original owner may still retain mineral rights under the right-of-way easement, but not the right to exclude people from passing through certain parts of what would otherwise be private land. A government may build a right of way on land it already owns, for example a public park or "unowned" land leftover from

5215-575: Is a separate technology that has been more successful in specialized services than in a commuter transit role. The use of the generic term light rail avoids some serious incompatibilities between British and American English . The word tram , for instance, is generally used in the UK and many former British colonies to refer to what is known in North America as a streetcar , but in North America tram can instead refer to an aerial tramway , or, in

5364-602: Is a significant amount of overlap between the technologies; similar rolling stock may be used for either, and it is common to classify streetcars or trams as a subcategory of light rail rather than as a distinct type of transportation. However, some distinctions can be made, though systems may combine elements of both. Low-floor light rail lines tend to follow a reserved right-of-way and with trains receiving priority at intersections, and tend not to operate in mixed traffic, enabling higher operating speeds. Light rail lines tend to have less frequent stops than tramways, and operate over

5513-563: Is by far the most expensive in the US, at $ 179 million per mile, since it includes extensive tunneling in poor soil conditions, elevated sections, and stations as deep as 180 feet (55 m) below ground level. This results in costs more typical of subways or rapid transit systems than light rail. At the other end of the scale, four systems (Baltimore, Maryland; Camden, New Jersey; Sacramento, California; and Salt Lake City, Utah) incurred construction costs of less than $ 20 million per mile. Over

5662-461: Is defined as a right of way , and in addition there is a general presumption of access to the countryside. Private rights of way or easements also exist. Footpaths , bridleways and other rights of way in most of England and Wales are shown on definitive maps . A definitive map is a record of public rights of way in England and Wales. In law it is the definitive record of where a right of way

5811-426: Is especially important for wheelchair access, as narrower gauges (e.g. metre gauge) can make it challenging or impossible to pass the tram's wheels. Furthermore, standard-gauge rolling stock can be switched between networks either temporarily or permanently, and both newly built and used standard-gauge rolling stock tends to be cheaper to buy, as more companies offer such vehicles. Overhead lines supply electricity to

5960-502: Is expensive. Similarly, the most expensive US highway expansion project was the " Big Dig " in Boston, Massachusetts, which cost $ 200 million per lane mile for a total cost of $ 14.6 billion. A light rail track can carry up to 20,000 people per hour as compared with 2,000–2,200 vehicles per hour for one freeway lane. For example, in Boston and San Francisco, light rail lines carry 9,600 and 13,100 passengers per hour, respectively, in

6109-703: Is generally provided on ocean waters under the law of the sea , subject to national laws. Public access to tidal shores depends on the jurisdiction. In the United States , railroad right-of-way easements carry with them, under applicable state laws, the right to control access by the public and even by the owner of the underlying land. Most U.S. railroads employ their own police forces, who can arrest and prosecute trespassers found on their rights-of-way. Some railroad rights-of-way (both active and disused) include recreational rail trails . In Canada railroad rights of way are regulated by federal law. In October 1880

6258-575: Is hard to distinguish between what is called light rail, and other forms of urban and commuter rail. A system described as a light rail in one city may be considered to be a streetcar or tram system in another. Conversely, some lines that are called "light rail" are very similar to rapid transit ; in recent years, new terms such as light metro have been used to describe these medium-capacity systems. Some "light rail" systems, such as Sprinter , bear little similarity to urban rail, and could alternatively be classified as commuter rail or even inter-city rail. In

6407-559: Is impractical. Light metro systems are essentially hybrids of light rail and rapid transit. Metro trains are larger and faster than light rail trains, with stops being further apart. Many systems have mixed characteristics. Indeed, with proper engineering, a rail line could run along a street, then go underground, and then run along an elevated viaduct. For example, the Los Angeles Metro Rail 's A Line "light rail" has sections that could alternatively be described as

6556-546: Is located. The highway authority (normally the county council , or unitary authority in areas with a one-tier system) has a statutory duty to maintain a definitive map, though in national parks the national park authority usually maintains the map. In Scotland , a right of way is a route over which the public has been able to pass unhindered for at least 20 years . The route must link two "public places", such as villages, churches or roads. Unlike in England and Wales there

6705-491: Is more restricted than other parts of the UK, so that in many areas walkers can only enjoy the countryside because of the goodwill and tolerance of landowners. Permission has been obtained from all landowners across whose land the Waymarked Ways and Ulster Way traverse. Much of Northern Ireland's public land is accessible, e.g. Water Service and Forest Service land, as is land owned and managed by organisations such as

6854-399: Is no obligation on Scottish local authorities to signpost rights of way. However the charity Scotways , formed in 1845 to protect rights of way, records and signs the routes. The Land Reform (Scotland) Act 2003 codified in law traditional, non-motorised, access practices on land and water. Under the 2003 act a plain language explanation of rights is published by Scottish Natural Heritage:

7003-484: Is one of the highest capacity ones, having been upgraded in a series of expansions to handle 40,000 passengers per hour per direction, and having carried as many as 582,989 passengers in a single day on its Line 1 . It achieves this volume by running four-car trains with a capacity of up to 1,350 passengers each at a frequency of up to 30 trains per hour. However, the Manila light rail system has full grade separation and as

7152-659: Is restricted, and only 2% of all rivers have public access rights. The Rivers Access Campaign is being undertaken by the British Canoe Union (BCU) to open up the inland water-ways in England and Wales on behalf of members of the public. Canals are not, in general, public rights of way in England and Wales. Waterways in the care of the Canal & River Trust are accessible for use by boats, canoeists, paddleboarders and other watercraft upon payment of an appropriate licence fee. Walkers and cyclists can freely use

7301-407: Is similar to that of a traditional tram, while operating at a higher capacity and speed, often on an exclusive right-of-way. In broader use, it includes tram-like operations mostly on streets. A few light rail networks have characteristics closer to rapid transit or even commuter rail , yet only when these systems are fully grade-separated are they referred to as light metros . The term light rail

7450-450: Is terminated, full rights automatically revert to the owner of the real estate over which the right of way passed. Some jurisdictions have a separate formal process for terminating disused right-of-way easements involuntarily, such as adverse abandonment for railroads in the United States. This allows property owners to regain full use after a railroad stops running but does not initiate the legal abandonment process on its own. Railbanking

7599-425: Is up to the owner to sell it to abutters, a conservation non-profit, another transportation company, or some other buyer. Full land ownership generally cannot be lost due to disuse, but abandoned right-of-way land can be taken by the government due to non-payment of property tax , by escheat if no private owner can be found (due to death without heirs or disincorporation), or by eminent domain if it wishes to return

7748-490: The American Recovery and Reinvestment Act and federal formula funds. The "Trolley Renewal Project" would entail several improvements. Each station would get larger shelters to provide more protection from sun and rain, new benches, and digital "next arrival" signs. Worn-out infrastructure was replaced as needed, including rails, ties, catenary wires, power lines and electrical substations. The project also included

7897-542: The Cádiz TramBahia , where trams share track with commuter and long-distance trains from the main terminus in the city and curve off to serve cities without a railway connection. Some of the issues involved in such schemes are: There is a history of what would now be considered light rail vehicles operating on heavy rail rapid transit tracks in the US, especially in the case of interurban streetcars . Notable examples are Lehigh Valley Transit trains running on

In the Philippines , right of way disputes often arise when landowners block access to paths or roads that have been used by the public or specific individuals for a considerable period. The issue typically centers on whether

8195-634: The Green Line . The line also featured the first low-floor trolley vehicles, that allow passengers to board without climbing stairs and allowed passengers using wheelchairs to use a small bridge plate instead of the slower lifts on the older trains. But, the new vehicles could only operate on the Green Line, forcing passengers heading between Mission Valley and downtown San Diego to change trains in Old Town. (This restriction no longer applies.) In

The 2009 act abolished the doctrine of lost modern grant, and allows

8493-758: The London Underground and the New York City Subway . Conventional rail technologies including high-speed , freight, commuter , and rapid transit urban transit systems are considered "heavy rail". The main difference between light rail and heavy rail rapid transit is the ability for a light rail vehicle to operate in mixed traffic if the routing requires it. The world's first electric tram operated in Sestroretsk near Saint Petersburg , Russia , invented and operated on an experimental basis by Fyodor Pirotsky in 1880. The first tramway

8642-532: The National Trust and the Woodland Trust . Northern Ireland has much the same legal system as England, including concepts about the ownership of land and public rights of way, but it has its own court structure, system of precedents and specific legislation concerning rights-of-way and right-to-roam. In Québec City , Canada, which was originally built on the riverside bluff Cap Diamant in

8791-637: The Netherlands , this concept was first applied on the RijnGouweLijn . This allows commuters to ride directly into the city center, rather than taking a mainline train only as far as a central station and then having to change to a tram. In France, similar tram-trains are planned for Paris, Mulhouse , and Strasbourg ; further projects exist. In some cases, tram trains use previously abandoned or lightly used heavy rail lines in addition to or instead of still in use mainline tracks. In 2022, Spain opened

In other cases, the modern law is unclear; Victorian era laws on easements protect a property owner's rights, amplified by the 1937 constitution , which stipulate that a right of way has to be specifically dedicated to public use. Opposing these, those claiming general rights of way hark back to an anti- landed gentry position that lasted from

Later in the decade, the South Line was extended to the north, reaching Little Italy on July 2, 1992, and Old Town on June 16, 1996. The system was further expanded east from the Old Town station as the Mission Valley Line, which opened on November 23, 1997. It proceeded eastward from Old Town to Fashion Valley Mall , Mission Valley Mall, and San Diego Stadium . At

The ability to temporarily restrict public access is commonly exercised without notice by shooting, forestry or wind farm operators, but does not extend to public rights of way. In Scotland the public have a higher degree of freedom on rights of way than on open land. Blocking a right of way in Scotland is a criminal obstruction under the Highways Act, just as in England and Wales, but

Operating on two-minute headways using traffic signal progression, a well-designed two-track system can handle up to 30 trains per hour per track, achieving peak rates of over 20,000 passengers per hour in each direction. More advanced systems with separate rights-of-way using moving block signaling can exceed 25,000 passengers per hour per track. Most light rail systems in

The Breakneck Stairs or Breakneck Steps (French: Escalier casse-cou ), Quebec City's oldest stairway, were built in 1635. Originally called escalier Champlain "Champlain Stairs", escalier du Quêteux "Beggars' Stairs", or escalier de la Basse-Ville "Lower Town Stairs", they were given their current name in

10877-624: The 1970s was proven to have been a technical failure by the following decade. After World War II, the Germans retained many of their streetcar networks and evolved them into model light rail systems ( Stadtbahnen ). With the exception of Hamburg , all large and most medium-sized German cities maintain light rail networks. The concept of a "limited tramway" was proposed by American transport planner H. Dean Quinby in 1962. Quinby distinguished this new concept in rail transportation from historic streetcar or tram systems as: The term light rail transit

11026-523: The Blue Line between America Plaza and San Ysidro boosts frequency to every 7.5 minutes during weekdays. The San Diego Trolley operates on a proof-of-payment system. Passengers must have proof of fare (ticket or pass) before boarding. Self-serve ticket-vending machines located at each station sell one-way paper tickets and passes (one day and monthly) on the Pronto Card . (An older fare card that

11175-640: The Blue Line) was completed by January 27, 2015, The project, including remaining station and track renovations, was completed in late 2015. In 2011, SANDAG received key approval for the Mid-coast extension of the Blue Line , running from Old Town Transit Center 11 miles (17.7 km) north to the University City community, serving major activity and employment centers such as Mission Bay Park,

11324-548: The CPO's 1975 Regional Transportation Plan and was guided by principles set by the MTDB board: the corridor should extend a long-distance and offer high-speed operation, the system should be at grade in a mostly exclusive right-of-way , capital costs should be low, and operating deficits should be minimized. Phase 1 studied over 100 miles of potential corridors with 45 miles of corridor recommended for further evaluation in Phase 2. At about

11473-495: The French city of Bordeaux , the tramway network is powered by a third rail in the city center, where the tracks are not always segregated from pedestrians and cars. The third rail (actually two closely spaced rails) is placed in the middle of the track and divided into eight-metre sections, each of which is powered only while it is completely covered by a tram. This minimizes the risk of a person or animal coming into contact with

11622-476: The Green Line, these are Fashion Valley Transit Center , Stadium , Mission San Diego , and Grantville . There is just one trolley station in the system that is underground – SDSU Transit Center – also on the Green Line. About half of San Diego Trolley stations offer free park and ride lots. Most trolley stations offer connections to MTS bus lines . The San Diego Trolley's four main lines operate regular service between 5 am and 11:30 pm, seven days

11771-437: The MTDB established San Diego Trolley, Inc. to operate and maintain the new light rail system and on July 26, 1981, service began. Trains operated every 20 minutes (timed to meet at four passing tracks on the single track sections) between 5 am and 9 pm and carried approximately 10,000 passengers a day. In light of the strong ridership, construction of the second phase was started almost immediately, which involved double-tracking

11920-680: The Old Town Transit Center), and continuing to nine new trolley stations: Tecolote Road, Clairemont Drive, Balboa Avenue, Nobel Drive, VA Medical Center, UCSD West/Pepper Canyon, UCSD East/Voigt Drive, Executive Drive, and UTC. The northern terminal station, UTC, is part of the UTC Transit Center, at Westfield UTC in the University City/UC San Diego area. In early 2024, the MTS proposed truncating

12069-477: The Orange Line was truncated to Santa Fe Depot and the Blue Line to America Plaza . The new alignment meant all lines now passed through downtown and created a universal transfer point for all lines at 12th & Imperial Transit Center. By January 9, 2013, all stations on the Orange Line had been rebuilt, allowing low-floor LRVs to begin service on a second line. Rebuilding of the remaining stations (all on

12218-485: The Regional Transportation Plan which included a 58-mile (93 km) intermediate capacity fixed guideway system (an untested technology at the time) at a cost of $ 1.5 billion. In the early 1970s, three state legislative acts would set the stage for the construction of mass transit in the San Diego region. Transportation Development Act, signed by Gov. Ronald Reagan in 1971, earmarked 25% of

12367-515: The S70 US ("Ultra Short") which retains the low-floor design, but would be the same length as the older high-floor vehicles (80 feet (24 m)). The MTS and SANDAG agreed to purchase a total of 65 vehicles, which would arrive between September 2011 and January 27, 2015. However, there was not enough funding to replace all 123 high-floor cars at once. The decision was made to retire the original Siemens-Duewag U2 LRVs, and operate three-car trains with

12516-467: The SD&AE La Mesa Branch from downtown San Diego to El Cajon. With all the planning in place, construction of the 15.9-mile (25.6 km) "South Line" transit corridor (the southern portion of today's Blue Line ) was able to begin just one month after acquisition in December 1979 and would be accomplished in two phases. The first phase of the project cost $ 86 million, which included the purchase of

12665-543: The SD&AE corridor and purchasing 10 additional vehicles. Upon completion of double-tracking in February 1983, the total cost of the project was $ 116.6 million. The success of the San Diego Trolley would also spark a nationwide revival of light rail in the late 1980s, with lines built in several other mid-sized cities ( Buffalo , Denver , Portland , Sacramento and San Jose ). The San Diego Trolley added

12814-452: The SD&AE, 14 light rail vehicles, construction of a single-tracked electrified light rail line along the 14.2-mile (22.9 km) SD&AE Main Line and construction of a 1.7-mile (2.7 km) section of new street running tracks in downtown San Diego. To control costs, only minor rehabilitation was conducted on the SD&AE corridor, with the MTDB replacing about 40% of the ties, welding

12963-406: The San Diego Trolley. MTS also has a more extensive slideshow and timeline available. The last day of streetcar operation in San Diego was April 23, 1949. On July 19, 1981 electric railcars returned to San Diego streets on the first modern American light rail system integrated with its bus system. Electric rail service in San Diego traces its roots back to 1891 when John D. Spreckels incorporated

13112-662: The US are the NJ Transit River Line from Camden to Trenton and Austin's Capital MetroRail , which have received exemptions to the provision that light rail operations occur only during daytime hours and Conrail freight service only at night, with several hours separating one operation from the other. The O-Train Trillium Line in Ottawa also has freight service at certain hours. With its mix of right-of-way types and train control technologies, LRT offers

13261-455: The US as a whole, excluding Seattle, new light rail construction costs average about $ 35 million per mile. By comparison, a freeway lane expansion typically costs $ 1.0 million to $ 8.5 million per lane mile for two directions, with an average of $ 2.3 million. However, freeways are frequently built in suburbs or rural areas, whereas light rail tends to be concentrated in urban areas, where right of way and property acquisition

13410-666: The United States and in North America . In Britain, modern light rail systems began to appear in the 1980s, starting with the Tyne and Wear Metro from 1980 and followed by the Docklands Light Railway (DLR) in London in 1987, continuing into the 1990s including the establishment of the Manchester Metrolink in 1992 and the Sheffield Supertram from 1994. Due to varying definitions, it

13559-590: The United States are limited by demand rather than capacity (by and large, most American LRT systems carry fewer than 4,000 persons per hour per direction), but Boston's and San Francisco's light rail lines carry 9,600 and 13,100 passengers per hour per track during rush hour. Elsewhere in North America, the Calgary C-Train and Monterrey Metro have higher light rail ridership than Boston or San Francisco. Systems outside North America often have much higher passenger volumes. The Manila Light Rail Transit System

13708-472: The United States, "light rail" has become a catch-all term to describe a wide variety of passenger rail systems. Light rail corridors may constitute a fully segregated corridor, a dedicated right-of-way on a street, an on-street corridor shared with other traffic, a corridor shared with other public transport, or a corridor shared with pedestrians. The most difficult distinction to draw is that between low-floor light rail and streetcar or tram systems. There

13857-640: The Western United States, the transcontinental railroad was funded by government land grants that gave railroads both the physical right-of-way and surrounding land that could be sold after becoming valuable parcels connected to the long-distance transportation network. In new developments, the government may create the road network in cooperation with the land-owning developer or parcel owners—easement boundaries are defined in writing, and public roads formally "dedicated" as government-maintained. In some jurisdictions, utility companies may by law have

14006-758: The […] owner", a restatement of the centuries-old principle of Nec vi, nec clam, nec precario . A court order granting a right of way is personal to the applicant for their lifetime, and cannot be inherited or assigned. In England and Wales , other than in the 12 Inner London boroughs and the City of London , public rights of way are paths on which the public have a legally protected right to pass and re-pass. The law in England and Wales differs from that in Scotland in that rights of way only exist where they are so designated (or are able to be designated if not already) whereas in Scotland any route that meets certain conditions

14155-415: The ability of buses to travel closer to each other than rail vehicles and their ability to overtake each other at designated locations allowing express services to bypass those that have stopped at stations. However, to achieve capacities this high, BRT station footprints need to be significantly larger than a typical LRT station. In terms of cost of operation, each bus vehicle requires a single driver, whereas

14304-467: The board selected light rail as the lone guideway transit technology to be studied (it would also be compared to several all-bus alternatives). In making the decision to pursue light rail, the MTBD board said it best followed the principles it laid out as light rail can offer high-speed travel, the right-of-way is flexible, and construction costs can be low when at-grade construction is maximized. The technology

14453-569: The building of Canada's first transcontinental rail line, the Canadian Pacific Railway , started. It was built by a consortium contracted by the government, and financed by CA$ 25 million in credit and required 25 million acres (100,000 km ) of land. In addition, the government defrayed surveying costs and exempted the railway from property taxes for 20 years. In the United Kingdom , railway companies received

14602-866: The case of the Disney amusement parks , even a land train . (The usual British term for an aerial tramway is cable car , which in the US usually refers to a ground-level car pulled along by subterranean cables .) The word trolley is often used as a synonym for streetcar in the United States but is usually taken to mean a cart, particularly a shopping cart, in the UK and elsewhere. Many North American transportation planners reserve streetcar for traditional vehicles that operate exclusively in mixed traffic on city streets, while they use light rail to refer to more modern vehicles operating mostly in exclusive rights of way, since they may operate both side-by-side targeted at different passenger groups. The difference between British English and American English terminology arose in

14751-421: The closure of Glasgow Corporation Tramways (one of the largest in Europe) in 1962. Although some traditional trolley or tram systems continued to exist in San Francisco and elsewhere, the term "light rail" has come to mean a different type of rail system as modern light rail technology has primarily post-WWII West German origins. An attempt by Boeing Vertol to introduce a new American light rail vehicle in

14900-412: The creation of the country), or seize land or an easement by eminent domain (compulsory purchase). Private companies can purchase land or easements, and in some cases (such as private toll roads (turnpikes), canals, and railroads in the 18th and 19th centuries) have been given the power of eminent domain for the limited purpose of providing a certain type of transportation between specified locations. In

15049-415: The day. This combination of factors limits roads carrying only automobile commuters to a maximum observed capacity of about 3,000 passengers per hour per lane. The problem can be mitigated by introducing high-occupancy vehicle ( HOV ) lanes and ride-sharing programs, but in most cases, policymakers have chosen to add more lanes to the roads, despite a small risk that in unfavorable situations an extension of

15198-755: The direct translation, which is city rail (the Norwegian term, by bane , means the same). However, UMTA finally adopted the term light rail instead. Light in this context is used in the sense of "intended for light loads and fast movement", rather than referring to physical weight. The infrastructure investment is also usually lighter than would be found for a heavy rail system. The American Public Transportation Association (APTA), in its Glossary of Transit Terminology, defines light rail as: ...a mode of transit service (also called streetcar, tramway, or trolley) operating passenger rail cars singly (or in short, usually two-car or three-car, trains) on fixed rails in

15347-622: The eastern terminus of both the Green and Orange lines to El Cajon Transit Center , replacing the easternmost sections of both lines with a Copper Line between El Cajon and Santee station . The Copper Line was scheduled begin operations on September 29, 2024. The line would later begin operating that day. As of 2024, trolley service operates on four daily lines: the Blue, Green, Orange, and Copper lines, and traveling through 65 total miles of mostly double-track rail and serving 62 stations. A fifth line,

15496-673: The extensive damages, SP petitioned the Interstate Commerce Commission to abandon the SD&AE on August 9, 1977. The MTDB immediately began studying the SD&AE corridor between downtown San Diego and the San Ysidro Port of Entry for joint use by electric light rail and freight trains. In June 1978, the MTDB found the entire joint-use project feasible. At the same time, the San Diego County Board of Supervisors became concerned about

15645-419: The extensive network of towpaths that run alongside the canals in England and Wales. See Towpath#Britain for information on the legal status of towpaths. In Canada rivers are crown land and there is a legal "right to navigate over navigable waters. However, the difficult legal question is what constitutes navigable waters. There is no federal or provincial law defining this, nor is there any list of waters

15794-418: The hurricane-damaged line. The deal closed on August 20, 1979, with the final acquisition occurring on November 1, 1979. The MTDB quickly secured a deal with the San Diego and Imperial Valley Railroad to continue freight service along the line. The purchase gave MTDB ownership of two sections of right-of-way that could be used for mass transit: the SD&AE Main Line from downtown San Diego to San Ysidro, and

15943-427: The jointed rail, constructing electric catenaries, and installing an absolute block signal system. Funding for the project came entirely from Transportation Development Act state sales tax and local gas tax revenues. Federal funds were not actively sought due to the locally perceived notion that San Diego would not qualify due to low population densities, uncongested highways, and undefined corridors. In August 1980,

16092-667: The lack of publicly accessible rights of way maps in Scotland makes it very difficult to enforce. The unofficial National Catalogue of Rights of Way (CROW), compiled by the Scottish Rights of Way and Access Society (Scotways), in partnership with Scottish Natural Heritage, and the help of local authorities. There are three categories of rights of way in CROW: Northern Ireland has very few public rights of way and access to land in Northern Ireland

16241-458: The late 19th century when Americans adopted the term "street railway", rather than "tramway", with the vehicles being called "streetcars" rather than "trams". Some have suggested that the Americans' preference for the term "street railway" at that time was influenced by German emigrants to the United States (who were more numerous than British immigrants in the industrialized Northeast), as it is

16390-535: The late 2000s, as parts of the San Diego Trolley approached 30 years old, the system was in need of an overhaul of its oldest facilities. Also, after the success of the low-floor trolley cars on the Green Line, the MTS wanted to operate similar vehicles on all lines. Officials secured $ 660 million in funding after the 2008 election as voters passed the TransNet half-cent local sales tax and two statewide transportation bond measures. The project also received funding from

16539-524: The latter is described as light rail. In those places, trams running on mixed rights-of-way are not regarded as a light rail but considered distinctly as streetcars or trams. However, the requirement for saying that a rail line is "separated" can be quite low—sometimes just with concrete "buttons" to discourage automobile drivers from getting onto the tracks. Some systems such as Seattle's Link had on-road mixed sections but were closed to regular road traffic, with light rail vehicles and buses both operating along

16688-399: The light rail concept was the "Shaker Heights Rapid Transit" which started in the 1920s, was renovated in 1980-81 and is now part of RTA Rapid Transit . Many original tram and streetcar systems in the United Kingdom , United States , and elsewhere were decommissioned starting in the 1950s as subsidies for the car increased. Britain abandoned its tram systems, except for Blackpool , with

16837-731: The mid-19th century, because of their steepness. The stairs have been restored several times, including an 1889 renovation by Charles Baillargé . Rights of way have been created in the US, both by historic use ( prescription ) and by grants made by the national and state governments, local authorities and private landowners. Trails that had been established by indigenous peoples were used by Europeans settling North America. Some became highways, while others have been incorporated recently into hiking trails. Examples include: Natchez Trace ; Santa Fe Trail ; Bozeman Trail . In Seattle , there are over 500 public stairways. Some rights of way in North America are hundreds of years old. In Newfoundland

16986-438: The neighboring property, and if the property is sold it would convey to the new owners. Courts may declare this type of easement exists as a matter of equity to resolve a dispute, if the easement was apparently left out of property deeds despite obvious necessity, if there was an apparent intent to create an easement but this was never formalized, or in some jurisdictions if an undocumented right of way has been in continuous use for

17135-475: The new low-floor LRVs in the front and back, and an older high-floor Siemens SD-100 car in the middle. In late 2010, work to rebuild the stations started at Old Town Transit Center and worked south. By September 2, 2012, work was completed on the Old Town and Bayshore lines, allowing for a realignment of service. The Green Line was extended from its former western terminus in Old Town south to 12th & Imperial Transit Center 's Bayside Terminal platform, while

17284-503: The next decade, the CPO researched various technologies including improvements to local buses, express buses, heavy rail, light rail, and advanced technologies. The CPO also closely studied the San Francisco Bay Area Rapid Transit (BART) system, then under construction. Ultimately, the early studies went nowhere due to disagreements between stakeholders and a lack of funding. In 1975, the CPO published

17433-465: The old and new systems. Since the 1980s, Portland, Oregon , has built all three types of system: a high-capacity light rail system in dedicated lanes and rights-of-way, a low-capacity streetcar system integrated with street traffic, and an aerial tram system . The opposite phrase heavy rail , used for higher-capacity, higher-speed systems, also avoids some incompatibilities in terminology between British and American English, for instance in comparing

17582-470: The other stations are located in the cities of Chula Vista , El Cajon , La Mesa , Lemon Grove , National City , and Santee . Most of the stations in the San Diego Trolley system are 'at-grade' stations. There are 10 aerial stations, mostly on the Blue Line, with some on the Green Line. For the Blue Line, these are Nobel Drive , VA Medical Center , UC San Diego Central Campus , UC San Diego Health La Jolla , Executive Drive , and UTC Transit Center. For

17731-461: The peak direction during rush hour. Right-of-way (transportation) Rights-of-way in the legal sense (the right to pass through or to operate a transportation facility) can be created in a number of different ways. In some cases, a government, transportation company, or conservation non-profit purchases the full ownership of real estate , including everything above and below the ground. Many rights-of-way are created instead by easement , which

17880-418: The potential loss of freight service on the SD&AE, which was seen as vital to the county's economic interests and the continued viability of San Diego as a deep-water port. The county commissioned its own study to examine using a portion of the SD&AE tracks for passenger service which would share the track with freight services, the motivation being the transit services could share the costs of maintaining

18029-439: The property to some productive use. Property outside of linear corridors, especially if improved with buildings (such as railroad stations and large highway interchanges) is more likely to be fully owned and sold off as real estate. Legal discontinuation or abandonment may trigger public auction or negotiated sale of government-owned land. Some right-of-way easements are created because the only way to access certain parcels from

18178-488: The public can use". Under federal law, all natural inland waterways of the United States are classifiable as "navigable" or "non-navigable". Navigable rivers, lakes, ponds, and streams are treated as "public highways", open to surface passage by anyone. The doctrine of navigable servitude gives the federal government primary regulatory power over navigable waters, but users are also subject to state police power . Ownership of non-tidal non-navigable waters goes along with

18327-556: The required clearance height can be reduced significantly compared to conventional light rail vehicles. Reference speed from major light rail systems, including station stop time, is shown below. However, low top speed is not always a differentiating characteristic between light rail and other systems. For example, the Siemens S70 LRVs used in the Houston METRORail and other North American LRT systems have

18476-651: The right to "resume" land for a right of way, by means of private Acts of Parliament . Resumption means compulsory acquisition of land. The various designations of railroad right of way are as follows: Construction of houses/buildings beside railway right-of-way presents a significant safety risk. For example, the Hanoi Department of Tourism in Vietnam ordered the permanent closure of cafes and shops along Hanoi Train Street for safety reasons despite its being

18625-432: The right-of-way that is often separated from other traffic for part or much of the way. Light rail vehicles are typically driven electrically with power being drawn from an overhead electric line via a trolley [pole] or a pantograph ; driven by an operator onboard the vehicle; and may have either high platform loading or low-level boarding using steps." However, some diesel-powered transit is designated light rail, such as

18774-415: The road network might lead to increased travel times ( Downs–Thomson paradox , Braess's paradox ). By contrast, light rail vehicles can travel in multi-car trains carrying a theoretical ridership up to 20,000 passengers per hour in much narrower rights-of-way , not much more than two car lanes wide for a double track system. They can often be run through existing city streets and parks , or placed in

18923-401: The roads. Typically roadways have 1,900 passenger cars per lane per hour (pcplph). If only cars are allowed, the capacity will be less and will not increase when the traffic volume increases. When there is a bus driving on this route, the capacity of the lane will be higher and will increase when the traffic level increases. And because the capacity of a light rail system is higher than that of

19072-671: The same as the German term for the mode, Straßenbahn (meaning "street railway"). A further difference arose because, while Britain abandoned all of its trams after World War II except in Blackpool , eight major North American cities ( Toronto , Boston , Philadelphia , San Francisco , Pittsburgh , Newark , Cleveland , and New Orleans ) continued to operate large streetcar systems. When these cities upgraded to new technology, they called it light rail to differentiate it from their existing streetcars since some continued to operate both

19221-550: The same time, a working paper presented an evaluation of four guideway technologies: light rail, two categories of heavy rail, and Automated Small Vehicle Transit . In August 1977, the MTDB board selected the South Bay region for the detailed Phase 2 study. There would be several potential corridors to consider, including along freeways (Interstate highways I-5, I-8 & I-805 and State Routes 94 & 16), along existing railroad rights-of-way, and arterial roads. In October 1977

19370-412: The same time, the South Line (which now traveled north of downtown San Diego to Old Town) and East Line of the system were renamed the Blue Line and the Orange Line, respectively. The Mission Valley East extension, which opened on July 10, 2005, built the only underground station in the system at San Diego State University , as well as its highest elevated station at Grantville. This line was then renamed

19519-408: The standard gauge is that standard railway maintenance equipment can be used on it, rather than custom-built machinery. Using standard gauges also allows light rail vehicles to be conveniently moved around using the same tracks as freight railways. Additionally, wider gauges (e.g. standard gauge) provide more floor clearance on low-floor trams that have constricted pedestrian areas at the wheels, which

19668-404: The submerged land, and issues of public access and trespass are treated similarly to private property on land. This may be determined by explicit deed, or implicitly as an extension of ownership of adjacent land, depending on the local ownership history and state law. The right to roam in northern European countries, including Scotland, usually includes rivers and lakes. Freedom of navigation

19817-413: The success of the system helped spark a nationwide revival of light rail. In 2023, the trolley had the highest ridership of any light rail system in the United States, with 38,047,300 annual rides, or about 129,800 per weekday as of the third quarter of 2024. 2023 is the 42nd anniversary of the San Diego Trolley, and the MTS has prepared a brief historical review of San Diego trolleys, and in particular

19966-479: The switch to low-floor LRVs was that the traditional Siemens S70 , like those ordered for the Green Line, were over 90 feet (27 m) long, so a three-car train would not fit within downtown San Diego's 240 feet (73 m) blocks. The MTS teamed up with the Utah Transit Authority, which faced a similar problem with its system. The solution for both agencies was a specialized design Siemens called

20115-551: The system was a success with the public, gaining up to 190,000 passengers per day. Automatic train operation is employed on light rail networks, tracking the position and speed of a train and hence adjusting its movement for safety and efficiency. One line of light rail (requires 7.6 m, 25' right of way) has a theoretical capacity of up to 8 times more than one 3.7 m (12 foot) lane on a freeway, excluding busses, during peak times. Roads have ultimate capacity limits that can be determined by traffic engineering , and usually experience

20264-523: The three major lines. Since the opening of the Copper Line, riders bound for Arnele Avenue , Gillespie Field , or Santee must transfer at El Cajon Transit Center . Six trolley stations are end-of-line stations: 12th & Imperial Transit Center, Courthouse, El Cajon Transit Center, Santee, San Ysidro Transit Center , and UTC Transit Center . Thirty-seven stations are within the city limits of San Diego , serving various neighborhoods in San Diego ;

20413-585: The tracks. San Diego County proposed operating either commuter rail trains or self-powered diesel rail cars . In 1978, the Interstate Commerce Commission denied the request to abandon the SD&AE, prompting Southern Pacific to offer the railroad for sale to anyone willing to maintain freight operations on the line. The MTDB stepped in and offered to buy the SD&AE for $ 18.1 million if the Southern Pacific fully repaired

20562-503: The trams, making it safe on city streets. Several systems in Europe and a few recently opened systems in North America use diesel -powered trains. When electric streetcars were introduced in the late 19th century, conduit current collection was one of the first ways of supplying power, but it proved to be much more expensive, complicated, and trouble-prone than overhead wires . When electric street railways became ubiquitous, conduit power

20711-430: The trolley system's stations operate as transfer stations, which allow passengers to transfer between lines. 12th & Imperial Transit Center allows for transferring between the Blue, Green, and Orange lines, serving as a universal transfer point for most riders in the system. The adjacent Santa Fe Depot / America Plaza / Courthouse stations, which are within walking distance of each other, also allow for transfer among

20860-401: The typical gentle slopes and connectivity of railroad rights-of-way. Some courts will extend the real property boundaries of abutters to the middle of the abandoned right-of-way, even if the right-of-way is outside the boundaries defined in the property deed. Treating the property as if it were an undocumented easement in this way avoids long, narrow strips of unproductive land. This is known as

21009-460: The vast majority of light rail systems. This avoids the danger potentially presented by an electrified third rail . The Docklands Light Railway uses an inverted third rail for its electrical power, which allows the electrified rail to be covered and the power drawn from the underside. Trams in Bordeaux , France, use a special third-rail configuration where the power is only switched on beneath

21158-434: The widest range of latitude of any rail system in the design, engineering, and operating practices. The challenge in designing light rail systems is to realize the potential of LRT to provide fast, comfortable service while avoiding the tendency to overdesign that results in excessive capital costs beyond what is necessary to meet the public's needs. The BART railcar in the following chart is not generally considered to be

21307-428: Was new for the United States , but was well established in Germany . On September 10, 1976, nature intervened, setting off a chain of events that would help decide the corridor to be used. Hurricane Kathleen destroyed parts of San Diego and Arizona Eastern Railway (SD&AE) Desert Line (east of San Diego), which at the time was owned by Southern Pacific (SP) railroad. The SD&AE offered freight service with

21456-543: Was coined in 1972 by the U.S. Urban Mass Transportation Administration (UMTA; the precursor to the Federal Transit Administration ) to describe new streetcar transformations that were taking place in Europe and the United States.
