Rapid transit or mass rapid transit ( MRT ) or heavy rail , commonly referred to as metro , is a type of high-capacity public transport that is generally built in urban areas . A grade separated rapid transit line below ground surface through a tunnel can be regionally called a subway , tube , metro or underground . They are sometimes grade-separated on elevated railways , in which case some are referred to as el trains – short for "elevated" – or skytrains . Rapid transit systems are railways , usually electric , that unlike buses or trams operate on an exclusive right-of-way , which cannot be accessed by pedestrians or other vehicles.
102-583: The Baltimore Metro SubwayLink is a rapid transit line serving Baltimore , Maryland, and its northwestern suburbs, operated by the Maryland Transit Administration . The segment in Downtown Baltimore is underground, while most of the line outside the central city is elevated or at surface grade. In 2023, the line had a ridership of 1,988,300, or about 16,300 per weekday as of the third quarter of 2024. The origins of
204-580: A pantograph , and have a maximum speed of 60 miles per hour (97 km/h). When delivered, they were the first transit vehicles in the United States to employ A/C propulsion. Each LRV is powered by four 275 hp (205 kW) motors (1,100 hp or 820 kW total); the middle truck of three-car trains is unpowered. As of 2024, the MTA had 53 individual light rail cars. During typical weekday peak-time service, approximately 30 to 35 cars are required;
306-635: A 4-station extension to Linthicum on April 2, 1993, and an additional 2-station extension to Glen Burnie on May 20, 1993. Station placement and design were intended to be flexible and change over time, as stations could be built or closed at low cost. However, they were at times dictated by politics rather planning: proposed stops in Ruxton , Riderwood, and Cross Keys were not built due to local opposition, while Mt. Royal station (now Mt. Royal/MICA station ) and Timonium Business Park station (now Timonium station ) were built despite nearly being removed from
408-425: A body of water), which are potential congestion sites but also offer an opportunity for transfers between lines. Ring lines provide good coverage, connect between the radial lines and serve tangential trips that would otherwise need to cross the typically congested core of the network. A rough grid pattern can offer a wide variety of routes while still maintaining reasonable speed and frequency of service. A study of
510-480: A bus or the Metro requires a new one-way fare or a pass. Automated ticket vending machines that sell tickets and passes are available at all Light RailLink stations. The Light RailLink's ticketing is based on a proof-of-payment system. Passengers must have a ticket or pass before boarding. Maryland Transit Administration Police officers ride some trains and randomly check passengers to make sure that they are carrying
612-454: A code for its stations. Unlike that of Singapore's MRT, it is mostly numbers. Based on the line number, for example Sinyongsan station, is coded as station 429. Being on Line 4, the first number of the station code is 4. The last two numbers are the station number on that line. Interchange stations can have multiple codes. Like City Hall station in Seoul which is served by Line 1 and Line 2. It has
714-651: A code of 132 and 201 respectively. The Line 2 is a circle line and the first stop is City Hall, therefore, City Hall has the station code of 201. For lines without a number like Bundang line it will have an alphanumeric code. Lines without a number that are operated by KORAIL will start with the letter 'K'. With widespread use of the Internet and cell phones globally, transit operators now use these technologies to present information to their users. In addition to online maps and timetables, some transit operators now offer real-time information which allows passengers to know when
816-583: A conventional track is often provided in case of flat tires and for switching . There are also some rubber-tired systems that use a central guide rail , such as the Sapporo Municipal Subway and the NeoVal system in Rennes , France. Advocates of this system note that it is much quieter than conventional steel-wheeled trains, and allows for greater inclines given the increased traction of
918-405: A dedicated right-of-way are typically used only outside dense areas, since they create a physical barrier in the urban fabric that hinders the flow of people and vehicles across their path and have a larger physical footprint. This method of construction is the cheapest as long as land values are low. It is often used for new systems in areas that are planned to fill up with buildings after the line
1020-451: A fire damaged a portion of the subway system, prompting a brief closure. Regular service resumed a few days later. Rapid transit Modern services on rapid transit systems are provided on designated lines between stations typically using electric multiple units on railway tracks . Some systems use guided rubber tires , magnetic levitation ( maglev ), or monorail . The stations typically have high platforms, without steps inside
1122-418: A large number of factors, including geographical barriers, existing or expected travel patterns, construction costs, politics, and historical constraints. A transit system is expected to serve an area of land with a set of lines , which consist of shapes summarized as "I", "L", "U", "S", and "O" shapes or loops. Geographical barriers may cause chokepoints where transit lines must converge (for example, to cross
SECTION 10
#17327721175501224-652: A large part of the network, for example, in outer suburbs, runs at ground level. In most of Britain , a subway is a pedestrian underpass . The terms Underground and Tube are used for the London Underground . The North East England Tyne and Wear Metro , mostly overground, is known as the Metro . In Scotland , the Glasgow Subway underground rapid transit system is known as the Subway . In Ireland ,
1326-452: A line is obtained by multiplying the car capacity, the train length, and the service frequency . Heavy rapid transit trains might have six to twelve cars, while lighter systems may use four or fewer. Cars have a capacity of 100 to 150 passengers, varying with the seated to standing ratio – more standing gives higher capacity. The minimum time interval between trains is shorter for rapid transit than for mainline railways owing to
1428-594: A major business park and a mall. On December 6, two short but important branches were added to the system: a 0.3-mile (0.48 km) spur in Baltimore that provided a link to the Penn Station intercity rail hub, and a 2.7-mile (4.3 km) spur to the terminal of BWI Airport . On September 6, 1998, the Hamburg Street station (now Stadium/Federal Hill station ) opened as an infill station between
1530-615: A metro. In Spain, such systems are present in Madrid , Barcelona , Bilbao and Valencia . In Portugal, Lisbon has a metro. The Italian cities of Catania , Genoa , Milan , Naples , Rome and Turin also have metro lines. In Germany and Austria they rapid transit is known as U-Bahn , which are often supported by S-Bahn systems. In Germany, U-Bahn systems exist in Berlin , Hamburg , Munich and Nuremberg , while in Austria such
1632-669: A new spur from the Central Light RailLink line by crossing the Middle Branch of the Patapsco River south of Interstate 95 . The MTA plans to transition the system from high floor vehicles to low floor LRVs and requested information from low-floor LRV vendors in January 2023. The Red Line is a planned 14.1-mile (22.7 km), 19-station light rail line traveling east–west that would intersect with
1734-764: A portion running in the median of Interstate 795 . A further extension of 1.6 mi (2.5 km) from Charles Center to Johns Hopkins Hospital opened on May 31, 1995. Once the project was completed in 1995, the total cost for the Metro SubwayLink stood at $ 1.392 billion. The current system is 15.4 mi (24.8 km) long, consisting of 6.2 mi (10 km) underground, 2.2 mi (3.5 km) elevated, and 7.0 mi (11.3 km) at grade. Eight of its 14 stations are underground, at depths from 52 ft (16 m) to 112 ft (34 m) below street level. Its elevated stations stand from 25 ft (7.6 m) to 28 ft (8.5 m) above ground. When
1836-408: A rapid transit setting. Baltimore Light RailLink The Baltimore Light RailLink (formerly Baltimore Light Rail , also known simply as the " Light Rail ") is a light rail system serving Baltimore , Maryland , United States, and its northern and southern suburbs. It is operated by the Maryland Transit Administration (MTA Maryland). In downtown Baltimore, it uses city streets . Outside
1938-499: A somewhat higher number of cars are put into service immediately after Orioles and Ravens games. For weekday service, as well as days of Orioles games or events at the CFG Bank Arena or Baltimore Convention Center , trains going from Hunt Valley to Cromwell and BWI Airport are generally run with two cars, while three-car trains are put into service for Ravens games and major downtown events. The Penn Station-Camden Yards shuttle
2040-565: A specialized transit police may be established. These security measures are normally integrated with measures to protect revenue by checking that passengers are not travelling without paying. Some subway systems, such as the Beijing Subway , which is ranked by Worldwide Rapid Transit Data as the "World's Safest Rapid Transit Network" in 2015, incorporates airport-style security checkpoints at every station. Rapid transit systems have been subject to terrorism with many casualties, such as
2142-634: A supplementary set of essentially identical cars being purchased in 1986 for the line expansion. The cars, marketed by Budd as the Universal Transit Vehicle , are identical to those formerly used on the Miami Metrorail ; the two agencies built their systems at the same time and saved money by sharing a single order. A number of Budd cars have been retired. Trains draw power from the electric third rail . The cars are 75 feet (22.86 m) long, 10 feet (3.05 m) wide, and have

#17327721175502244-608: A system exists in Vienna . In addition, the small, car-free town of Serfaus in the Austrian state of Tyrol also features a short U-Bahn line. There are no U-Bahn systems in the German-speaking part of Switzerland, but the city of Lausanne has its own, small metro system. In Zurich, Switzerland's largest city, a project for a U-Bahn network was stopped by a referendum in the 1970s and instead its S-Bahn system
2346-592: A top speed of 70 mph (110 km/h). Cars are semi-permanently attached in married pairs and joined up to form 4-car trains, which is the normal train length. 6-car trains are used during peak rush hours. Each car can hold up to 166 passengers (76 seated, 90 standing). The fleet had a significant overhaul between 2002 and 2005. Seats were reupholstered, and the floors were replaced. External destination rollsigns were replaced with LED displays; internal systems that display train destinations and upcoming stop announcements were also installed. In July 2017, MTA announced
2448-468: A total of 13.4 million passenger trips for the year. Vehicles operated at an average cost of $ 11.59 per revenue mile. Local buses, in comparison, performed at a cost of $ 13.57 per revenue mile. The Metro SubwayLink has a total of 14 stations. Light RailLink (at Cultural Center ) Most Metro SubwayLink stations are served by a number of MTA bus routes. In 1984, just months after Metro first started operating, many feeder routes were created that were given
2550-549: A valid ticket or pass and can issue criminal citations for those without one. Civilian Fare Inspectors also conduct ticket checks, alighting those without fare. Most Light RailLink stations are served by several MTA bus routes and passengers can make platform-to-platform transfers with the MARC Camden Line at Camden Yards and with the MARC Penn Line at Penn Station. There are no cross-platform connections with
2652-737: Is a shortened reference to a metropolitan area . Rapid transit systems such as the Washington Metrorail , Los Angeles Metro Rail , the Miami Metrorail , and the Montreal Metro are generally called the Metro . In Philadelphia , the term "El" is used for the Market–Frankford Line which runs mostly on an elevated track, while the term "subway" applies to the Broad Street Line which is almost entirely underground. Chicago 's commuter rail system that serves
2754-608: Is a single corporate image for the entire transit authority, but the rapid transit uses its own logo that fits into the profile. A transit map is a topological map or schematic diagram used to show the routes and stations in a public transport system. The main components are color-coded lines to indicate each line or service, with named icons to indicate stations. Maps may show only rapid transit or also include other modes of public transport. Transit maps can be found in transit vehicles, on platforms , elsewhere in stations, and in printed timetables . Maps help users understand
2856-592: Is about a one-half mile walk from State Center, and MARC Camden Station is about five blocks from Lexington Market Metro station. As of 2024, the line currently uses cars manufactured by the Budd Company in Northeast Philadelphia . The first set of additional, new cars are presently manufactured at Hitachi Rail Italy in Florida . Most of the 100 Budd-built cars were delivered in 1983 with
2958-506: Is built. Most rapid transit trains are electric multiple units with lengths from three to over ten cars. Crew sizes have decreased throughout history, with some modern systems now running completely unstaffed trains. Other trains continue to have drivers, even if their only role in normal operation is to open and close the doors of the trains at stations. Power is commonly delivered by a third rail or by overhead wires . The whole London Underground network uses fourth rail and others use
3060-416: Is necessary, rolling stock with a smaller loading gauge from one sub network may be transported along other lines that use larger trains. On some networks such operations are part of normal services. Most rapid transit systems use conventional standard gauge railway track . Since tracks in subway tunnels are not exposed to rain , snow , or other forms of precipitation , they are often fixed directly to
3162-555: Is referred to simply as "the subway", despite 40% of the system running above ground. The term "L" or "El" is not used for elevated lines in general as the lines in the system are already designated with letters and numbers. The "L" train or L (New York City Subway service) refers specifically to the 14th Street–Canarsie Local line, and not other elevated trains. Similarly, the Toronto Subway is referred to as "the subway", with some of its system also running above ground. These are

3264-781: Is scheduled for completion in March 2018. The overhauled cars began testing in early 2016. By 2021 the original order of ABB vehicles had their interiors upgrades with security cameras, LED lighting, and LCD screens that show the train's position along the line. In February 2024, the Maryland Transit Administration announced that they had been awarded $ 213,696,341 in grant funding from the U.S. Department of Transportation’s Federal Transit Administration’s Rail Vehicle Replacement program to replace all 52 aging Light Rail vehicles in its fleet with new, modern railcars. While there are several plans and proposals to expand
3366-412: Is serviced by at least one specific route with trains stopping at all or some of the line's stations. Most systems operate several routes, and distinguish them by colors, names, numbering, or a combination thereof. Some lines may share track with each other for a portion of their route or operate solely on their own right-of-way. Often a line running through the city center forks into two or more branches in
3468-569: Is significant overlap on these routes, most of the system sees 10-minute peak and 15-minute off-peak headways; stations in the downtown section between Mt. Royal and Camden Yards are served by six trains an hour off-peak and eight trains an hour at peak. (Paradoxically, the Fairgrounds-Hunt Valley section actually sees longer headways at peak hours.) Most of the light rail's route is on dedicated right-of-way that has grade crossings equipped with crossing gates . The remainder of
3570-748: Is the most commonly used term for underground rapid transit systems used by non-native English speakers. Rapid transit systems may be named after the medium by which passengers travel in busy central business districts ; the use of tunnels inspires names such as subway , underground , Untergrundbahn ( U-Bahn ) in German, or the Tunnelbana (T-bana) in Swedish. The use of viaducts inspires names such as elevated ( L or el ), skytrain , overhead , overground or Hochbahn in German. One of these terms may apply to an entire system, even if
3672-493: Is typically operated with one-car trains. The MTA also owns a variety of maintenance of way equipment, which can use diesel power in emergencies. A mid-life upgrade of the light rail vehicles began in 2013. On September 9, 2013, a contract for mid-life overhauls of the light rail vehicles was awarded to Alstom . Five vehicles at a time were sent for rebuilding, involving testing, removal of all interior and exterior components and replacement with new propulsion systems. The overhaul
3774-627: The Dublin Area Rapid Transit is despite the name considered a commuter rail due to usage of mainline railways. In France, large cities, such as Paris , Marseille and Lyon , feature a Métro . Also the smaller cities of Lille Rennes have a light metro. Furthermore, Brussels in Belgium, and Amsterdam and Rotterdam in the Netherlands have metro systems in place. Several Southern European contries also have
3876-738: The Hanover Subdivision along the former Western Maryland Railway route. The route then enters the median of Interstate 795, which it occupies until it reaches the Owings Mills terminus. Trains heading towards Johns Hopkins Hospital are referred to as "eastbound", while trains heading towards Owings Mills are "westbound". A trip from one end of the line to the other takes about half an hour. Headways range from eight minutes during daytime peak to eleven minutes late at night and on weekends. Trains run from 5 a.m. to midnight on weekdays and from 6 a.m. to midnight on weekends. As of 2024,
3978-752: The Hudson and Manhattan Railroad K-series cars from 1958, the New York City Subway R38 and R42 cars from the late-1960s, and the Nagoya Municipal Subway 3000 series , Osaka Municipal Subway 10 series and MTR M-Train EMUs from the 1970s, were generally only made possible largely due to the relatively generous loading gauges of these systems and also adequate open-air sections to dissipate hot air from these air conditioning units. Especially in some rapid transit systems such as
4080-429: The London Underground . In 1868, New York opened the elevated West Side and Yonkers Patent Railway , initially a cable-hauled line using stationary steam engines . As of 2021 , China has the largest number of rapid transit systems in the world – 40 in number, running on over 4,500 km (2,800 mi) of track – and was responsible for most of the world's rapid-transit expansion in
4182-740: The Metropolitan Railway opened publicly in London in 1863. High capacity monorails with larger and longer trains can be classified as rapid transit systems. Such monorail systems recently started operating in Chongqing and São Paulo . Light metro is a subclass of rapid transit that has the speed and grade separation of a "full metro" but is designed for smaller passenger numbers. It often has smaller loading gauges, lighter train cars and smaller consists of typically two to four cars. Light metros are typically used as feeder lines into

4284-578: The Montreal Metro (opened 1966) and Sapporo Municipal Subway (opened 1971), their entirely enclosed nature due to their use of rubber-tyred technology to cope with heavy snowfall experienced by both cities in winter precludes any air-conditioning retrofits of rolling stock due to the risk of heating the tunnels to temperatures that would be too hot for passengers and for train operations. In many cities, metro networks consist of lines operating different sizes and types of vehicles. Although these sub-networks may not often be connected by track, in cases when it
4386-589: The Prague Metro . The London Underground and Paris Métro are densely built systems with a matrix of crisscrossing lines throughout the cities. The Chicago 'L' has most of its lines converging on The Loop , the main business, financial, and cultural area. Some systems have a circular line around the city center connecting to radially arranged outward lines, such as the Moscow Metro 's Koltsevaya Line and Beijing Subway 's Line 10 . The capacity of
4488-685: The Singapore MRT , Changi Airport MRT station has the alphanumeric code CG2, indicating its position as the 2nd station on the Changi Airport branch of the East West Line. Interchange stations have at least two codes, for example, Raffles Place MRT station has two codes, NS26 and EW14, the 26th station on the North South Line and the 14th station on the East West Line. The Seoul Metro is another example that utilizes
4590-450: The deep tube lines . Historically, rapid transit trains used ceiling fans and openable windows to provide fresh air and piston-effect wind cooling to riders. From the 1950s to the 1990s (and in most of Europe until the 2000s), many rapid transit trains from that era were also fitted with forced-air ventilation systems in carriage ceiling units for passenger comfort. Early rapid transit rolling stock fitted with air conditioning , such as
4692-409: The linear motor for propulsion. Some urban rail lines are built to a loading gauge as large as that of main-line railways ; others are built to a smaller one and have tunnels that restrict the size and sometimes the shape of the train compartments. One example is most of the London Underground , which has acquired the informal term "tube train" due to the cylindrical shape of the trains used on
4794-432: The 15 world largest subway systems suggested a universal shape composed of a dense core with branches radiating from it. Rapid transit operators have often built up strong brands , often focused on easy recognition – to allow quick identification even in the vast array of signage found in large cities – combined with the desire to communicate speed, safety, and authority. In many cities, there
4896-488: The 1995 Tokyo subway sarin gas attack and the 2005 " 7/7 " terrorist bombings on the London Underground. Some rapid transport trains have extra features such as wall sockets, cellular reception, typically using a leaky feeder in tunnels and DAS antennas in stations, as well as Wi-Fi connectivity. The first metro system in the world to enable full mobile phone reception in underground stations and tunnels
4998-621: The 2010s. The world's longest single-operator rapid transit system by route length is the Shanghai Metro . The world's largest single rapid transit service provider by number of stations (472 stations in total) is the New York City Subway . The busiest rapid transit systems in the world by annual ridership are the Shanghai Metro, Tokyo subway system , Seoul Metro and the Moscow Metro . The term Metro
5100-532: The 21st century, most new expansions and systems are located in Asia, with China becoming the world's leader in metro expansion, operating some of the largest and busiest systems while possessing almost 60 cities that are operating, constructing or planning a rapid transit system . Rapid transit is used for local transport in cities , agglomerations , and metropolitan areas to transport large numbers of people often short distances at high frequency . The extent of
5202-604: The 53-car fleet. Service resumed on December 23. The Light RailLink system consists of a main north–south line on which 28 of the system's 33 stops are located. There are two branches on the southern end to BWI Airport and Glen Burnie that have two stations each and one spur in Baltimore City for Penn Station that can only be entered heading north and exited heading south. There are still single-track sections north of Timonium, where headways are limited to 15 minutes. The Light RailLink system has two train runs. One runs

#17327721175505304-540: The BWI Airport spur remain single tracked. On July 10, 2019, part of the northbound platform at Convention Center station fell into a sinkhole caused by a broken water main. The line was closed between Camden and North Avenue until August 19. On December 7, 2023, MTA Maryland announced the system would shut down indefinitely after inspections revealed a fire hazard in the rolling stock. A free shuttle bus service connected Light Rail stations as repairs were made to
5406-764: The Central Light RailLink line at Stockholm Street, in between Hamburg Street and Westport . The new station would be located near a proposed new MARC station west of Russell Street, and would provide additional access to the Baltimore Greyhound Bus Terminal , the Horseshoe Casino , and new businesses in the Carroll-Camden Industrial Area. In January 2016, plans were unveiled by Sagamore Development Company, owned by Under Armour CEO Kevin Plank , regarding
5508-589: The Metro SubwayLink lie in the Baltimore Area Mass Transportation Plan published in 1965, which envisioned six rapid transit lines radiating out from a central city loop. Planning studies from 1968 proposed a rail transit system 71 mi (114 km) long. As the vision was translated into reality, the original concept was trimmed to a 28 mi (45 km) system in the Phase 1 plan, published in 1971. This plan involved two of
5610-635: The Metro SubwayLink opened on November 21, 1983, only the "Northwest" line of the 1965 plan had come to fruition. This 7.6 mi (12.2 km) segment provided service between Charles Center in Downtown Baltimore and the Reisterstown Plaza shopping center in the northwest of the city. On July 20, 1987, a 6.1 mi (9.8 km) addition extended the line from Reisterstown Plaza to Owings Mills in Baltimore County, with
5712-410: The Metro SubwayLink, Light RailLink, and local buses: a one-way trip costs $ 2.00. Daily, weekly, and monthly unlimited-ride passes are also available that are good on all three transit modes. A passenger with a one-way ticket can change Light RailLink trains if necessary to complete their journey, the only instance of a one-way MTA ticket being good for a ride on more than one vehicle, but transferring to
5814-588: The Metro SubwayLink. There is no direct connection from the Metro SubwayLink to the Light RailLink or MARC commuter rail. However, the Metro SubwayLink's Lexington Market Station is a 200-yard (180 m) walk from the Light RailLink stop of the same name , and the State Center station is about 1.5 blocks away from the Light RailLink's Cultural Center station . Baltimore Penn Station
5916-403: The Metro SubwayLink. The Lexington Market subway and light rail stations are a block apart and connected only via surface streets. Baltimore's Light RailLink vehicles (LRVs) were built by ABB Traction , the U.S. division of ABB . The initial set was delivered in 1991–1992 as the line was being built; a supplemental order of similar cars built by AAI Corporation was delivered in 1997, when
6018-478: The beginning of rapid transit. Initial experiences with steam engines, despite ventilation, were unpleasant. Experiments with pneumatic railways failed in their extended adoption by cities. In 1890, the City & South London Railway was the first electric-traction rapid transit railway, which was also fully underground. Prior to opening, the line was to be called the "City and South London Subway", thus introducing
6120-462: The central portions of the city, the line is built on private rights-of-way , mostly from the defunct Northern Central Railway , Baltimore and Annapolis Railroad and Washington, Baltimore and Annapolis Electric Railway . The system had a ridership of 3,546,300, or about 15,400 per weekday, as of the third quarter of 2024. The origins of the Light RailLink lie in a 1966 Baltimore area transit plan that envisioned six rapid transit lines radiating from
6222-556: The city center. By 1983, only one of the plan's lines—the "Northwest" line—had been built, becoming the Metro SubwayLink . Much of the plan's "North" and "South" lines ran along rights-of-way once used by interurban streetcar lines and the commuter rail routes of the Northern Central Railway , Washington, Baltimore and Annapolis Electric Railway , and Baltimore and Annapolis Railroad . Beginning in

Over the years, the number of M-lines had shrunk, as many of the routes were consolidated. In 2008, routes designated with the letter "M" were renamed to plain two-digit designations. Finally, on August 30, 2009, the last four were either renumbered or eliminated, with no routing changes made; they continue to act as feeder routes to
6426-414: The display of the transit network. Often this has the effect of compressing the distance between stations in the outer area of the system, and expanding distances between those close to the center. Some systems assign unique alphanumeric codes to each of their stations to help commuters identify them, which briefly encodes information about the line it is on, and its position on the line. For example, on

Boston's subway system is known locally as "The T". In Atlanta , the Metropolitan Atlanta Rapid Transit Authority goes by the acronym "MARTA." In the San Francisco Bay Area , residents refer to Bay Area Rapid Transit by its acronym "BART". The New York City Subway
6630-471: The existing Fairgrounds and Warren Road stations in Texas, Cockeysville . An island was built at this point on the line in conjunction with the 2005 double-tracking work to provide a turn-back point for trains not going all the way to Hunt Valley, which could be converted into a station at a later date. In the 2015 South Baltimore Gateway Masterplan, the city of Baltimore proposed a new light rail stop along
6732-400: The existing Westport and Camden Yards stations. Adjacent to M&T Bank Stadium , it was initially only open during Ravens games and other major stadium events, but became a full-time stop on July 1, 2005. To save money, much of the system was built with only a single track. While this allowed the system to be constructed and opened quickly, it limited the system's flexibility: much of
6834-407: The existing Light RailLink downtown; this would be a separate service, with no track connection to the existing Light RailLink, though there would be opportunities for transfer between the two in the vicinity of University Center / Baltimore Street . The line would operate in a total of 4.7-mile (7.6 km) of tunnels through the downtown area (and along Cooks Lane), with the majority of the rest of

The articulated cars are 95 feet (28.96 m) long over coupler faces, 9.5 feet (2.90 m) wide, and 12.5 feet (3.81 m) high, and can accommodate 85 seated and 91 standing passengers. The cars operate on 4 ft 8 + 1 ⁄ 2 in ( 1,435 mm ) standard gauge track. One-, two- and three-car trains are all routinely seen in service. Trains are powered by 750 volt DC from overhead lines via
7038-404: The fare prices for MTA buses, the Metro SubwayLink, and the Light RailLink travel are as follows: Farebox recovery in the system is only 28%. This is comparable to other similarly sized systems in the continental United States, but low by international standards. For fiscal year 2010, the MTA reported 95% on-time performance for the system. It averaged 3.0 passenger trips per revenue mile, with
7140-470: The first trains of the day until 10 a.m., and from 4 p.m. to 6 p.m.), the BWI–Hunt Valley and Glen Burnie–Fairgrounds routes see 20-minute headways; at other times on weekdays and all day on weekends, there are 30-minute headways on both routes (with Glen Burnie trains traveling all the way to Hunt Valley). The Camden Yards-Penn Station route sees 30-minute headways at all times. Because there
7242-516: The floor rather than resting on ballast , such as normal railway tracks. An alternate technology, using rubber tires on narrow concrete or steel roll ways , was pioneered on certain lines of the Paris Métro and Mexico City Metro , and the first completely new system to use it was in Montreal , Canada. On most of these networks, additional horizontal wheels are required for guidance, and
7344-646: The full length of the main line between Hunt Valley and either BWI Airport or Glen Burnie, alternating between the two every other trip, with some off-peak trains originating or terminating at either North Avenue or Fairgrounds instead of Hunt Valley. The other—the Penn-Camden Shuttle—only runs through downtown between Penn Station and Camden Station. The light rail operates from 4:00 a.m. to 12:45 a.m. on weekdays, 4:15 a.m. to 12:45 a.m. on Saturdays, and 10 a.m. to 10 p.m. on Sundays and major holidays. At peak hours on weekdays (from
7446-439: The interconnections between different parts of the system; for example, they show the interchange stations where passengers can transfer between lines. Unlike conventional maps, transit maps are usually not geographically accurate, but emphasize the topological connections among the different stations. The graphic presentation may use straight lines and fixed angles, and often a fixed minimum distance between stations, to simplify
7548-507: The late 1980s, Governor of Maryland and former Baltimore mayor William Donald Schaefer pushed for a transit line along the plan's "North" and "South" corridors, motivated in part by a desire to establish a rail transit link to the new baseball park being built at Camden Yards for the Baltimore Orioles . Light RailLink was built quickly and inexpensively without federal funds, a rarity for a U.S. transit project. The initial system
7650-547: The line was restricted to 17-minute headways , with no way to reduce headways during peak hours. Federal money was acquired to double track most of the system; much of the line south of downtown Baltimore was shut down in 2004 and north of downtown shut down in 2005 in order to complete this project. The northern section up to Timonium reopened in December 2005; the rest opened in February 2006. The line north of Gilroy Road and
7752-602: The lines of the Lyon Metro includes a section of rack (cog) railway , while the Carmelit , in Haifa, is an underground funicular . For elevated lines, another alternative is the monorail , which can be built either as straddle-beam monorails or as a suspended monorail . While monorails have never gained wide acceptance outside Japan, there are some such as Chongqing Rail Transit 's monorail lines which are widely used in
7854-557: The main rapid transit system. For instance, the Wenhu Line of the Taipei Metro serves many relatively sparse neighbourhoods and feeds into and complements the high capacity metro lines. Some systems have been built from scratch, others are reclaimed from former commuter rail or suburban tramway systems that have been upgraded, and often supplemented with an underground or elevated downtown section. Ground-level alignments with
7956-418: The network map "readable" by illiterate people, this system has since become an "icon" of the system. Compared to other modes of transport, rapid transit has a good safety record, with few accidents. Rail transport is subject to strict safety regulations , with requirements for procedure and maintenance to minimize risk. Head-on collisions are rare due to use of double track, and low operating speeds reduce
8058-402: The next vehicle will arrive, and expected travel times. The standardized GTFS data format for transit information allows many third-party software developers to produce web and smartphone app programs which give passengers customized updates regarding specific transit lines and stations of interest. Mexico City Metro uses a unique pictogram for each station. Originally intended to help make
8160-958: The occurrence and severity of rear-end collisions and derailments . Fire is more of a danger underground, such as the King's Cross fire in London in November 1987, which killed 31 people. Systems are generally built to allow evacuation of trains at many places throughout the system. High platforms , usually over 1 meter / 3 feet, are a safety risk, as people falling onto the tracks have trouble climbing back. Platform screen doors are used on some systems to eliminate this danger. Rapid transit facilities are public spaces and may suffer from security problems: petty crimes , such as pickpocketing and baggage theft, and more serious violent crimes , as well as sexual assaults on tightly packed trains and platforms. Security measures include video surveillance , security guards , and conductors . In some countries
8262-603: The only two North American systems that are primarily called "subways". In most of Southeast Asia and in Taiwan , rapid transit systems are primarily known by the acronym MRT . The meaning varies from one country to another. In Indonesia , the acronym stands for Moda Raya Terpadu or Integrated Mass [Transit] Mode in English. In the Philippines , it stands for Metro Rail Transit . Two underground lines use
8364-581: The original six lines: a northwest line from Downtown Baltimore to Owings Mills and a south line to Glen Burnie and the airport. Phase 1 was approved for funding by the Maryland General Assembly in 1972. In response to lobbying by Anne Arundel County residents, the MTA eliminated the south line from Phase 1 plans in 1975; the Baltimore Light RailLink was later built over much of the planned south line corridor. When
8466-587: The outset. Budapest , Chicago , Glasgow , Boston and New York City all converted or purpose-designed and built electric rail services. Advancements in technology have allowed new automated services. Hybrid solutions have also evolved, such as tram-train and premetro , which incorporate some of the features of rapid transit systems. In response to cost, engineering considerations and topological challenges some cities have opted to construct tram systems, particularly those in Australia, where density in cities
8568-491: The plan because the University of Baltimore and a local business group funded them. Falls Road station was built with less parking than ridership required because community requests and a fence prevented riders from accessing a nearby commercial building. Three extensions to the system were added in 1997. On September 9, the line was extended north 4.5 miles (7.2 km) to Hunt Valley , adding five stations that served
8670-604: The purchase of 78 new railcars to replace the entire subway fleet. The cars are being built in Florida by Hitachi Rail Italy, and will be similar in appearance to those purchased for the Miami Metrorail. The Hitachi railcars generate electricity while braking, thus allowing the energy to power certain train systems and enabling the system to become more energy efficient. The first Hitachi cars were delivered in October 2023;
8772-908: The rapid transit system varies greatly between cities, with several transport strategies. Some systems may extend only to the limits of the inner city, or to its inner ring of suburbs with trains making frequent station stops. The outer suburbs may then be reached by a separate commuter rail network where more widely spaced stations allow higher speeds. In some cases the differences between urban rapid transit and suburban systems are not clear. Rapid transit systems may be supplemented by other systems such as trolleybuses , regular buses , trams , or commuter rail. This combination of transit modes serves to offset certain limitations of rapid transit such as limited stops and long walking distances between outside access points. Bus or tram feeder systems transport people to rapid transit stops. Each rapid transit system consists of one or more lines , or circuits. Each line
8874-486: The redevelopment of Port Covington in South Baltimore . The new plan for Port Covington calls for two proposed new light rail stations, along with new residential and commercial development. The first station would be located west of Hanover Street, and the other would be located at the intersection of East McComas Street and East Cromwell Street, just south of Federal Hill . This proposed extension would create
8976-409: The replacement of the rolling stock is set to occur in phases from 2024 to 2026. On February 11, 2018, the MTA announced a month-long closure of the entire system to complete emergency track repairs identified during a safety inspection. An aboveground portion of the system had already been shut down due to emergency inspections and repairs. The system reopened on March 9, 2018. In the summer of 2023,
9078-699: The route in downtown Baltimore between Camden Station and Mt. Royal uses shared right of way on Howard Street, where trains mix with automobile traffic and their movement is controlled by traffic signals. In 2007, a transit signal priority system was implemented on this section, resulting in time savings of 25%. From south of Falls Road to North Avenue, the light rail runs parallel to the Jones Falls Expressway , and from Camden Yards to north of Westport, it parallels Interstate 395 . North of Falls Road and south of Westport, it follows its own path towards its respective termini. MTA fares are identical for
9180-542: The rubber tires. However, they have higher maintenance costs and are less energy efficient. They also lose traction when weather conditions are wet or icy, preventing above-ground use of the Montréal Metro and limiting it on the Sapporo Municipal Subway, but not rubber-tired systems in other cities. Some cities with steep hills incorporate mountain railway technologies in their metros. One of
9282-663: The suburbs, allowing a higher service frequency in the center. This arrangement is used by many systems, such as the Copenhagen Metro , the Milan Metro , the Oslo Metro , the Istanbul Metro and the New York City Subway . Alternatively, there may be a single central terminal (often shared with the central railway station), or multiple interchange stations between lines in the city center, for instance in
9384-798: The system opened, it became the largest single user of Susan B. Anthony dollar coins in the United States. The installation of underground cellular service in the Metro SubwayLink tunnels began in September 2021 and was originally expected to be completed by June 2022. As of January 2024, the work has not been completed. The Metro SubwayLink has a single line that is shaped like a reverse "J". Trains head south underground from Johns Hopkins Hospital, turn west as they pass under Baltimore's central business district, turn north at Charles Center, and ultimately turn to face northwest at State Center. The route leaves its tunnel northwest of Mondawmin station, entering an elevated structure that parallels Wabash Avenue and
9486-409: The system operating at-grade and just a few aerial sections, as well as in the median of the former Interstate 170 freeway. The Red Line was cancelled by Governor Larry Hogan , who had campaigned against it in the 2014 Maryland gubernatorial election , on June 25, 2015. Wes Moore , his successor, indicated his intention to revive it shortly after being elected , and formally announced the return of
9588-481: The system, none are approved or funded. An independent commission on Baltimore-area transit made a number of suggestions in a 2002 report for new lines and expansions of existing lines. Newer proposals include expanding service on the existing Central Light RailLink line by extending Sunday service via the BaltimoreLink plan, as well as new stations and spurs. There are plans to add an infill station between
9690-714: The term subway . In Thailand , it stands for Metropolitan Rapid Transit , previously using the Mass Rapid Transit name. Outside of Southeast Asia, Kaohsiung and Taoyuan, Taiwan , have their own MRT systems which stands for Mass Rapid Transit , as with Singapore and Malaysia . In general rapid transit is a synonym for "metro" type transit, though sometimes rapid transit is defined to include "metro", commuter trains and grade separated light rail . Also high-capacity bus-based transit systems can have features similar to "metro" systems. The opening of London's steam-hauled Metropolitan Railway in 1863 marked
9792-467: The term Subway into railway terminology. Both railways, alongside others, were eventually merged into London Underground . The 1893 Liverpool Overhead Railway was designed to use electric traction from the outset. The technology quickly spread to other cities in Europe , the United States, Argentina, and Canada, with some railways being converted from steam and others being designed to be electric from
9894-511: The trains, requiring custom-made trains in order to minimize gaps between train and platform. They are typically integrated with other public transport and often operated by the same public transport authorities . Some rapid transit systems have at-grade intersections between a rapid transit line and a road or between two rapid transit lines. The world's first rapid transit system was the partially underground Metropolitan Railway which opened in 1863 using steam locomotives , and now forms part of
9996-601: The use of communications-based train control : the minimum headway can reach 90 seconds, but many systems typically use 120 seconds to allow for recovery from delays. Typical capacity lines allow 1,200 people per train, giving 36,000 passengers per hour per direction . However, much higher capacities are attained in East Asia with ranges of 75,000 to 85,000 people per hour achieved by MTR Corporation 's urban lines in Hong Kong. Rapid transit topologies are determined by
10098-559: Was Singapore's Mass Rapid Transit (MRT) system, which launched its first underground mobile phone network using AMPS in 1989. Many metro systems, such as the Hong Kong Mass Transit Railway (MTR) and the Berlin U-Bahn, provide mobile data connections in their tunnels for various network operators. The technology used for public, mass rapid transit has undergone significant changes in the years since
10200-751: Was a single 22.5-mile (36.2 km) line, all at-grade except for a bridge over the Middle Branch of the Patapsco River just south of downtown Baltimore. The line ran from Timonium in Baltimore County in the north to Glen Burnie in Anne Arundel County in the south. The line opened in stages over a 14-month period. The initial segment from Timonium Fairgrounds station (now Fairgrounds station ) to Camden Yards station opened for limited service for Orioles games on April 2, 1992 , and for full service on May 17. A three-station extension to Patapsco opened on August 20, 1992, followed by
10302-899: Was developed further. Other Central European countries also have metro lines, for example in the cities of Budapest (Hungary), Prague (Czech Republic) and Warsaw (Poland). In Eastern Europe , metro systems are in operation in Minsk (Belarus), Kyiv (Ukraine), Riga (Latvia), Vilnius (Lithuania) and Moscow (Russia). In Southeastern European countries, there are metro systems in Athens and Thessaloniki (Greece), Belgrade (Serbia), Sofia (Bulgaria) and Istanbul (Turkey). In Northern Europe , rapid transit systems exist in Copenhagen (Denmark), Oslo (Norway), Stockholm (Sweden) and Helsinki (Finland). Various terms are used for rapid transit systems around North America . The term metro
10404-702: Was low and suburbs tended to spread out . Since the 1970s, the viability of underground train systems in Australian cities, particularly Sydney and Melbourne , has been reconsidered and proposed as a solution to over-capacity. Melbourne had tunnels and stations developed in the 1970s and opened in 1980. The first line of the Sydney Metro was opened in 2019. Since the 1960s, many new systems have been introduced in Europe , Asia and Latin America . In
