93-728: TRAX is a light rail system in the Salt Lake Valley of Utah , in the United States , serving Salt Lake City and many of its suburbs throughout Salt Lake County . The system's official name, Transit Express , is rarely, if ever, used. The system is operated by the Utah Transit Authority (UTA). All TRAX trains are electric, receiving power from overhead wires. TRAX has 51 stations on three lines. The Blue Line provides service from Downtown Salt Lake City to Draper . The Red Line provides service from
186-515: A streetcar . The streetcar seemed to be the preferred alternative. On October 20, 2010, the S Line (known then as Sugar House Streetcar) received a $ 26 million federal grant that allowed the street car to be completed in less than two years. It used an existing rail line running along 2200 South from the Central Pointe TRAX Station to approximately 1100 East, near the primary Sugar House shopping district. The first phase of
279-724: 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

It operates weekends from approximately 5:00 am to nearly midnight, with a 15-minute headway on Saturdays and a 30-minute headway on Sundays. 117 active railcars 29 UTDC LRVs (1041–1069) were purchased second-hand from the Santa Clara VTA in 2004 and refurbished for service on TRAX. These were withdrawn from service in 2018. To handle

UTA does not sell naming rights for its stations, nor does it allow stations to be named after commercial businesses. Commercial advertising on TRAX platforms is prohibited, in order for the passengers to be able to notice the safety information. One exception to this rule occurred during

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

After the first year of operation, ridership on these portions of the Green and Red lines was less than was projected by UTA. However, UTA has stated the projected ridership was for the year 2015. Since these lines were opened for service years earlier than originally planned, the anticipated growth on the west side of Salt Lake Valley has just not happened, yet. UTA affirms that by 2015 ridership will meet
837-1142: 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
930-416: 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
1023-435: 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,

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
1209-642: 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
1302-407: 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
1395-534: 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
1488-481: 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
1581-470: 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
1674-575: 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
1767-602: 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
1860-563: 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
1953-426: 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

#17327913729342046-502: 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
2139-575: 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
2232-559: 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
2325-484: 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
2418-407: 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
2511-783: Is the company's largest light rail contract in the United States to date. In 2008, construction began on two new extensions: one extension of 5.1 miles (8.2 km) through West Valley City (now part of the Green Line ) and another extension of 10.6 miles (17.1 km) through the southwest portion of the Salt Lake Valley (now part of the Red Line ). Both extensions were debuted in ceremonial openings on August 2, 2011, and permanently opened for regular service on August 7. Both extensions were completed ahead of schedule and under budget. Upon completion of these expansions UTA adopted
2604-501: The 2002 Winter Olympics . For the duration of the games, the Arena and Temple Square stations were closed for security reasons, and during this time UTA allowed Coca-Cola to use the area of the unused Arena Station as part of its pin-trading center. The advertising restriction does not apply to the sides of the TRAX train cars or to UTA's buses. Not only does UTA have advertising signs on
2697-592: The 2034 Winter Olympics . In conjunction with the Mountain View Corridor project, plans were made by UTA to build a new TRAX line on the west side of the Salt Lake Valley along 5600 West (in the same general area as the Mountain View Corridor). The western line is anticipated to replace the yet-to-be-built 5600 West BRT bus rapid transit (BRT) line, which is currently stalled. In 2015, UTA announced plans to eventually expand
2790-542: 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
2883-568: The Federal Transit Administration on September 24, 2007, secured the remaining $ 500 million in funding for the light rail lines. These funds were used to finance the FrontLines 2015 expansion project, which added four TRAX extensions by 2015 (as well as an expansion to FrontRunner commuter rail ). In order to support planned TRAX expansion, UTA ordered 77 Siemens S70 light rail vehicles from Siemens AG . It

3069-758: 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

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

Such arrangements are almost impossible now, due to the Federal Railroad Administration refusing (for crash safety reasons) to allow non-FRA compliant railcars (i.e., subway and light rail vehicles) to run on the same tracks at the same times as compliant railcars, which includes locomotives and standard railroad passenger and freight equipment. Notable exceptions in

In 2023, the system had a ridership of 11,043,800, or about 43,800 per weekday as of the third quarter of 2024. TRAX operates seven days a week, with the exception of some holidays. It operates Monday through Friday from approximately 4:30 a.m. to 11:30 p.m. with

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
3627-624: 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

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

The second line from downtown to the University of Utah was completed in 2001 and extended in 2003. An extension to the Salt Lake City Intermodal Hub was completed in April 2008. In August 2011, two extensions to South Jordan and West Valley City were completed. With

Neighbors in the area have continually fought the route suggested by UTA. The route follows an old rail line and UTA already owned the right of way. An alternative route that would run down the middle of State Street was also studied by UTA. Use of

Initial proposals would have the line travel south to Herriman before either turning eastbound and passing through Riverton before terminating in Draper , or continuing south through Herriman toward the Rosecrest neighborhood and Zions Bank Stadium . UTA has historically discussed proposals to extend the Blue Line from Draper to Lehi and eventually Orem , as well as creating

In 2023, UTA published its Light Rail Strategic Plan, which highlighted plans by the agency to build new tracks along both 400 South and 400 West in Downtown Salt Lake City , connecting to the existing TRAX network at Ballpark to the south, Courthouse to the east, and either Salt Lake Central or Planetarium to the west. This expansion is also planned to include new stations at Pioneer Park and within

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
4464-455: 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

UTA published a draft Environmental Impact Statement for the new line that names the UTA right of way as the preferred route. The extension's first phase, which includes 3.5 miles (5.6 km) and three new stations, opened on August 18, 2013. When FrontRunner (UTA's commuter rail train) started running on April 26, 2008,

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

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

#17327913729344836-472: 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

An extension to the University Medical Center that added three new stations was completed on September 29, 2003, fifteen months ahead of schedule. An infill station at 900 South in Salt Lake City was constructed in 2005, and a second infill station, at 9400 South in Sandy ( Sandy Expo ), opened in August 2006.

(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

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

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

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

Also included are some of the urban streetcar/trolley systems that provide regular public transit service (operating year-round and at least five days per week), ones with data available from the American Public Transportation Association 's (APTA) Ridership Reports. This list does not include statistics for metro/rapid transit systems (see:
6603-406: The proposed TRAX extensions. A letter of intent signed with the Federal Transit Administration on September 24, 2007, secured the remaining funding for the light rail lines. Both the University Line and its extension to the University Medical Center were completed ahead of schedule. A daily ridership of 15,000 was expected for the initial 15-mile (24 km) line in 1999. By the beginning of 2008,
6696-556: 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
6789-521: The reroute of the Green Line for the Airport extension would have left the Green Line without any common station with FrontRunner. For several years a TRAX spur into the Salt Lake City neighborhood of Sugar House had been contemplated. A series of community meetings were held in Sugar House as part of a larger transit study undertaken by UTA. Several transit alternatives were presented to the neighborhood, including bus rapid transit , light rail, and
6882-432: 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
6975-415: 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
7068-401: 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
7161-671: 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
7254-528: The sides and rear of many of its buses, it also has many buses where the painting scheme of the full rear or even the entire bus is an advertisement (bus wrap). Other transit in the United States: Light rail Light rail (or light rail transit , abbreviated to LRT ) is a form of passenger urban rail transit that uses rolling stock derived from tram technology while also having some features from heavy rapid transit . The term
7347-408: 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
7440-551: 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
7533-633: The total number of stations to 28. UTA has two service centers for TRAX maintenance: the Midvale Rail Service Center, which is just off the Red Line in Midvale, southwest of its junction with the Blue Line, and the Jordan River Service Center, which is just off the Green Line northeast of River Trail. The Jordan River building was originally an old warehouse for ZCMI , which had recently ceased operations and
7626-503: 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
7719-460: 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
7812-434: 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
7905-459: 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. In Germany, the term Stadtbahn (to be distinguished from S-Bahn , which stands for Stadtschnellbahn ) was used to describe the concept, and many in UMTA wanted to adopt
7998-502: Was coined in 1972 in the United States as an English equivalent for the German word Stadtbahn , meaning "city railway". Different definitions exist in some countries, but in the United States, light rail operates primarily along exclusive rights-of-way and uses either individual tramcars or multiple units coupled together, with a lower capacity and speed than a long heavy rail passenger train or rapid transit system. Narrowly defined, light rail transit uses rolling stock that
8091-677: Was introduced in North America in 1972 to describe this new concept of rail transportation. Prior to that time the abbreviation "LRT" was used for " Light Rapid Transit " and " Light Rail Rapid Transit ". The first of the new light rail systems in North America began operation in 1978 when the Canadian city of Edmonton, Alberta , adopted the German Siemens-Duewag U2 system, followed three years later by Calgary, Alberta , and San Diego, California . The concept proved popular, with there now being numerous light rail systems in
8184-432: Was met with criticism. On October 10, 1988, Congress approved $ 5 million in funds to preserve land along the proposed light rail corridor. Funding for the light rail line, however, remained uncertain. After Salt Lake City won the bid for the 2002 Winter Olympics in 1995, UTA used the city's host status to accelerate obtaining funding through the Federal Transit Administration (FTA). Construction began in 1997. Protesters at
8277-556: Was part of the initial plans for the system, but the demand was not at the level needed for a station until recently. On September 21, 2006, a property tax hike proposal was replaced with a general transportation quarter-cent sales tax hike that was voted on and approved on November 7 of that year. On December 21, 2006, the Salt Lake County Council created a priority list for the sales tax, saying TRAX and commuter rail should take priority. A letter of intent signed with
8370-547: Was realigned slightly north and away from the Salt Lake City Intermodal Hub, allowing for the opening of the extension to the Salt Lake City International Airport . Several months later, in August 2013, the Blue Line was extended further south to Draper (which opened August 18, 2013). The extensions to South Jordan, West Valley City, Draper, and the Airport were funded in part by a Salt Lake County sales tax increase that would pay for all four of
8463-706: Was renovated into a rail service center in 1999. The Midvale Center was similarly repurposed from a former warehouse around the time of the Red and Green lines opening in 2011, it was also built to handle UTA's brand new Siemens S70 LRV's. Utah Railway (under its subsidiary Salt Lake City Southern Railroad and with contracts from BNSF ) and the Savage Bingham & Garfield Railroad both operate freight service over TRAX tracks via trackage rights . An additional infill station, 600 South Main Street in Salt Lake City, along all three lines, opened on July 26, 2022. The station
8556-632: Was the Gross-Lichterfelde tramway in Lichterfelde near Berlin in Germany, which opened in 1881. It was built by Werner von Siemens who contacted Pirotsky. It initially drew current from the rails, with overhead wire being installed in 1883. The first interurban to emerge in the United States was the Newark and Granville Street Railway in Ohio, which opened in 1889. An early example of
8649-527: Was used in those cities that did not permit overhead wires. In Europe, it was used in London, Paris, Berlin, Marseille, Budapest, and Prague. In the United States, it was used in parts of New York City and Washington, D.C. Third rail technology was investigated for use on the Gold Coast of Australia for the G:link light rail, though power from overhead lines was ultimately utilized for that system. In
