The Buenos Aires Underground, locally known as Subte, is a rapid transit system that serves the area of the city of Buenos Aires, Argentina. The first section of this network opened in 1913, making it the 13th subway in the world and the first underground railway in Latin America, the Southern Hemisphere, and the Spanish-speaking world, with the Madrid Metro opening five years later, in 1919. As of 2022, Buenos Aires is the only Argentine city with a metro system.
Line F is a planned addition to the Buenos Aires Underground. After some delays, the budget was announced in 2015 for the first phase of construction from Constitución to Córdoba at a total cost of between 700 and 800 million dollars. As of 2015, it was not yet known if construction would be done as a turnkey project or build to order, however construction was due to start in 2016.
Line A is the oldest line of the Buenos Aires Underground. Opened to the public on 1 December 1913, it was the first underground line in South America, the Southern Hemisphere and the Spanish-speaking world. It made Buenos Aires the 13th city in the world to have an underground transport service. The line stretches 9.8 km from Plaza de Mayo and San Pedrito and runs under the full length of the Avenida de Mayo and part of the Avenida Rivadavia, and is used by 258,000 people per day.
Line B of the Buenos Aires Underground runs 11.75 kilometres (7.30 mi) from Leandro N. Alem to Juan Manuel de Rosas in Villa Urquiza. Line B opened to the public on 17 October 1930.
Line C of the Buenos Aires Underground, that runs from Retiro to Constitución terminus, opened on 9 November 1934, and it has a length of 4.3 km (2.7 mi). It runs under Lima Sur, Bernardo de Irigoyen, Carlos Pellegrini, Esmeralda, la Plaza San Martín and Avenida Ramos Mejia streets. It not only connects to every other line on the system, but its termini at Retiro and Constitución also connect it to some of the most important commuter rail networks in Buenos Aires, such as the Mitre and Roca lines and also long-distance passenger services. It is thus an important artery in Buenos Aires' transport system. At the same time, it is also the shortest line in both terms of length and number of stations.
Line D of the Buenos Aires Underground runs from Catedral to Congreso de Tucumán. The line opened on 3 June 1937 and has been expanded to the north several times. The line is currently 11 km long and has 16 stations, while running approximately parallel to the city's coastline.
Line H is a line of the Buenos Aires Underground. The first phase, between Plaza Once and Caseros, which opened on 18 October 2007, currently stretches over 8.8 km between Hospitales and Facultad de Derecho stations. It is the first entirely new line built in Buenos Aires since the opening of Line E on 20 June 1944.
Line E of the Buenos Aires Underground runs from Retiro to Plaza de los Virreyes, a total distance of 12 km. Opened in 1944, the Line E was the last completely new line to be added to the Buenos Aires Underground, until 2007 when Line H was opened. The line has a history of being re-routed and extended due to having been historically the line with the lowest passenger numbers on the network.
Line I is a planned addition to the Buenos Aires Underground.
Caballito is a barrio (neighborhood) of the Argentine capital, Buenos Aires. It is the only barrio in the administrative division Comuna 6.
The Tranvía del Este, also known as the Puerto Madero Tramway, was a 12-block "demonstration" light rail line in the Puerto Madero neighborhood of Buenos Aires, Argentina, in operation from 2007 to 2012. It used French-built Alstom Citadis 302 trams on loan, initially from Mulhouse, France, and later from Madrid, Spain, and was operated by the rail company Ferrovías.
The Premetro is a 7.4-kilometer long (4.6 mi) light rail line that runs along the outskirts of Buenos Aires, connecting with the Buenos Aires Underground line E, at Plaza de los Virreyes station and then to General Savio, with a short branch to Centro Cívico. It opened in 1987 and is operated by Metrovías. Originally, the Premetro was to include many more lines, but shortly after the privatisation of the railways the projects were postponed and never materialised and only "Premetro E2" was built.
The San Martín line is a 70-kilometre (43 mi), 22-station commuter rail service in the metropolitan area of Buenos Aires, Argentina. The San Martín line operates from the city-centre terminus of Retiro north-west to Doctor Cabred in Luján Partido along a broad gauge line built by the British-owned Buenos Aires and Pacific Railway.
The Buenos Aires Metrobus is a 50.5 km (31.4 mi) network of dedicated separated lanes and stations for buses that serve the city of Buenos Aires, Argentina. Designed as a Bus Rapid Transit system, it mixes a few bi-articulated buses with conventional buses. The headway is the same as before the implementation of the system, and the buses on the system use the same brand as the main network, that is, maintaining their previous branding as common bus lines with their own numbers. The service operates 24 hours a day and 365 days a year, with 2-4 minute frequencies during the day and 10–15 minutes at night.
The first trams in Buenos Aires began operating in 1863 in what quickly became a vast network of tramways with the city being known as the "City of Trams" for having the highest tramway-to-population ratio in the world. In the 1920s, Buenos Aires had 875 km (544 mi) of tramways and 99 tram lines using 3000 carriages running throughout the city. By 1963, the vast majority of the network began to be dismantled, though some minor tram services continue in the city today.
Facultad de Derecho-Julieta Lanteri Station is a station on Line H of the Buenos Aires Underground which opened on 17 May 2018 as a one-station extension from Las Heras. It currently serves as the northern terminus of the line until it is extended to Retiro. It is located next to the University of Buenos Aires Faculty of Law and the City's Exhibition and Conventions Centre and it is near the Recoleta Cemetery and Fine arts museum.
Red de Expresos Regionales is a planned mass transit system in Buenos Aires which will connect the main rail terminals of the city through 16 km (9.9 mi) of tunnels with a central terminal. The tunnels will mean that the existing 815 km (506 mi) commuter rail network will be connected, with passengers being able to travel from one part of Greater Buenos Aires and La Plata to the other while only making one change at the new underground central terminal. The project is modelled on the Réseau Express Régional in Paris. It is estimated that after the completion of the project, combined with the current renewal of the commuter rail lines' rolling stock, passenger numbers will double from 1.4 million passengers per day to 3 million.
The CSR EMU is a series of electric multiple unit cars manufactured by CSR Corporation Limited for use on Buenos Aires' commuter rail network. As of 2015, the trains operated on three of the city's lines and 705 cars were manufactured, with each line using a different number of cars per train. They were created for use on lines electrified using both third rail and overhead lines.
The Siemens-Schuckert Orenstein & Koppel is an underground car formerly used on the Buenos Aires Underground first built by Siemens-Schuckert and Orenstein & Koppel in 1934, 1937 and 1944 with a smaller number of cars built in Argentina during the 1950s. The Siemens O&K rolling stock made up the entirety of the trains used on the three lines built by the Hispanic-Argentine Company for Public Works and Finances (CHADOPyF) and has since served on every line of the Underground from 1934 to 2016, with cars refurbished by the Emepa Group and Alstom continued to function on the network till 2017.
The Buenos Aires Underground has one of the most diverse metro fleets in the world, and has had some of the oldest models in operation on any network. The network began with a relatively standardised fleet, but throughout its over 100-year-long history, it has seen numerous purchases which have created cases where some lines operate numerous models. Recently there have been increased efforts to modernise and standardise the fleets, with large purchases from China CNR Corporation and Alstom.
