73-551: In earlier times the line was planned to run into the centre of Buenos Aires, through a long tunnel. But when the tunnel was finally built in 1930, it was taken over by the Underground system as part of Line B , and as a result, suburban passengers had to change at Federico Lacroze, named after its builder , about 6 km (3.7 mi) from the centre. The ramp connecting the Urquiza Line to Line B still exists, though it

146-410: A frequency of around 6 minutes. Under modernisation plans commenced in 2013, service frequencies increased to an average of one train every 2 minutes 20 seconds by 2019. Trains originally ran until 01:00 am, but following the privatisation of the service through concession to Metrovías , the company established an earlier closing time of 23:00 in 1994 to carry out works on the lines. This change

219-500: A magnetic strip (called Subtepass ) were used, however, these were phased out of the system in May 2016, opting instead only to use the digital cards, with the exception of some retired, disabled and student cards. In 2024, fares were raised to AR$ 574, an increase of 360%, as part of austerity policies introduced by President Javier Milei . Trains run from 05:00 until 23:00, every 3–4 minutes, for all lines except Line H which has

292-619: A total of 4 stations to each line between 2003 and 2013. During the same period, Line H was opened 2007, making it the first completely new line on the underground since Line E , excluding the Premetro . There have also been significant modernisations of infrastructure, signalling systems, stations and the network's rolling stock . The current contract expired on 31 December 2019 with bids put forward by: The network comprises six underground lines, labelled "A" to "E" and "H" and which are further identified by different colours, covering

365-405: A total route length of 56.7 kilometers (35.2 mi) and serving 90 stations. There is also one surface 7.4-kilometer (4.6 mi) Premetro "P" line with an additional 17 stations. Daily ridership was approximately 1.11 million in 2015. With the current usage patterns, the entire system is overstretched, and during weekdays overcrowded and with insufficient services. An expansion programme

438-550: A tree" from the Plaza de Mayo , something Miguel Delibes described as "restrictive". Current expansion efforts seek to address those restrictions by creating more north–south lines and moving termini away from the city centre. The current expansion plan was approved in the year 2000 under Law 670 and has seen the creation of Line H , as well as the extensions of Line A and Line B westwards. However, in 2015 an alternative plan has been proposed which would make numerous amendments to

511-414: Is 10.8 km. Construction was due to begin in 2020, once the northern extension of Line H is complete, and as originally planned, the line would have automatic trains and platform screen doors . [REDACTED] Line G will connect Retiro and Caballito / Villa Crespo ; 12.5 km long with 15 new stations. Originally, construction was due to start in 2012–2013, however city legislators opposed

584-417: Is a 7.4-kilometer (4.6 mi) tramway feeding Line E . The Premetro line opened in 1987. It carries approximately 2,300 passengers daily and is also run by Metrovías . In 2015, SBASE began making plans to refurbish and rebuild many of the stations, including a brand-new central terminal, as part of a plan to modernise the network, with the intent of increasing the amount of rolling stock in circulation. By

657-461: Is complemented by the 7.4-kilometre-long (4.6 mi) Premetro line , and the 26-kilometre-long (16 mi) Urquiza suburban line , with 17 more stations in total. Traffic on lines moves on the left because Argentina drove on the left at the time the system opened. Over a million passengers use the network, which also provides connections with the city's extensive commuter rail and bus rapid transport networks. The network expanded rapidly during

730-425: Is completely at grade (ground-level) and uses third rail current collection. It operates 20 hours a day, 7 days a week at 8-to-30-minute intervals. The Urquiza Line transported 15 million passengers in 2013. Originally the line was planned to run into the centre of Buenos Aires through a long tunnel. But when the tunnel was finally built in 1930, it ended up as Line B . The access ramp still exists and

803-679: Is extended to Plaza Italia from Retiro – a segment which in the original plan was part of Line F. In these plans, Line C is extended both northwards in a loop to Retiro bus station and southwards to the Buenos Aires Belgrano Sur Line railway station minor terminal. Such plans are subject to approval by the Buenos Aires City Legislature and would mean the annulment of many of the existing expansion plans outlined in Law 670. Some criticisms include

876-519: Is in use today, but for maintenance and storage purposes rather than for passenger services. The Urquiza Line itself opened in 1948, so suburban passengers travelling on the Underground's Line B have to transfer to the Urquiza Line at Federico Lacroze station, named after its builder , about 6 km (3.7 mi) from the city centre. Stations are listed from East to West or North to South. Stations in gray have yet to open. Stations in bold are

949-802: Is only used for maintenance purposes. Today Federico Lacroze has a direct connection to the line B underground station of the same name . Like the Buenos Aires Underground system, the Urquiza line uses the 1,435 mm ( 4 ft  8 + 1 ⁄ 2  in ) standard gauge rather than the 1,676 mm ( 5 ft 6 in ) broad gauge used in other interurban railways of Buenos Aires. The brothers Federico and Teófilo Lacroze were pioneers opening several horse-drawn tramway lines in Buenos Aires city, first in 1868 from Plaza de Mayo to Plaza Once and in 1870

1022-581: Is that in 1959, General Urquiza Railway acquired 30 PCC cars , built by the Pullman Standard in 1940. These were modified at the ends to operate in two, three or four-sectioned articulated formations like most modern LRVs. They were all retired by the mid-1960s, because they were too lightly built to handle the heavy passenger loads. The Pacific Electric coaches were used until 1974 when they were replaced by 128 new Toshiba Japanese underground coaches, third rail current collectors were installed and

1095-557: Is today Line C , a line which would link two of the city's most important rail terminals ( Constitución and Retiro ) together. In 1933 a third company, the Hispano-Argentina Company of Public Works and Finances ( Compañía Hispano–Argentina de Obras Públicas y Finanzas (CHADOPyF) , in Spanish) began construction of the other Underground lines. Line C's first section, Constitución railway station - Diagonal Norte ,

1168-530: Is underway, and it is expected to enlarge the network to 97 kilometers (60 mi) in the future. Similarly, new rolling stock has been incorporated across lines since 2013 to improve capacity and the last of the current orders are set to arrive in 2016 and followed by further orders of new rolling stock, which is expected to increase ridership figures to 1.8 million by 2019. Annual ridership in 2019: 321 296 964. Annual ridership in 2020: 73 650 077. Prior to 2024, standard fares cost AR$ 125 per trip on

1241-714: The 13th earliest subway network in the world and the first underground railway in Latin America , the Southern Hemisphere , and the Spanish-speaking world , with the Madrid Metro opening nearly six years later, in 1919. As of 2023, Buenos Aires is the only Argentine city with a metro system. Currently, the underground network's six lines—A, B, C, D, E, and H—comprise 56.7 kilometers (35.2 mi) of routes that serve 90 stations. The network

1314-587: The Chacarita neighbourhood and near the La Chacarita Cemetery . The station was opened on 17 October 1930 as the western terminus of the extension of the line from Federico Lacroze to Callao . It was a terminal station of line B from its inauguration and the inauguration of the extension to the Incas station on 9 August 2003. This station has connection to Federico Lacroze railway station ,

1387-423: The Madrid Metro in 1919. The creation of the underground was part of a number of other urban transformations. A system of public water and sewage was first completed in 1886 and expanded in the subsequent decades, and many streets were paved as part of this same urban renewal. The underground network was originally built and operated by three separate private companies and later nationalised in 1939. In 1952 it

1460-486: The National Reorganisation Process military junta. After a long period of stagnation, the Underground began to be expanded again with Lines B and E within the scope of these plans, though only the extension of Line E was commenced and completed before the transition to democracy where expansion was once again stalled. During this time, four Premetro feeder lines were planned leading out from

1533-455: The Red de Expresos Regionales was announced in 2015 as a project to connect all lines of the Buenos Aires commuter rail network through a series of tunnels, the Urquiza Line was curiously the only line left out of the project, despite being the only line with the infrastructure already in place to bring commuters directly to the project's planned central station. In June 2019 the line was deemed to

1606-556: The Urquiza Line and Premetro were offered as 20-year concessions to interested private parties. By 1995, Metrovías took over the Subte under a $ 395 million plan. Discussions on the need to build an underground transportation system in Buenos Aires began in the late nineteenth century, alongside the tramway system , which was one of the most extensive in the world at the time. The first trams appeared in 1870, and by about 1900

1679-586: The Urquiza Line . Construction began in 1927, and this line became Line B when it was inaugurated on 17 October 1930. During 17–18 December, 380,000 passengers travelled on the line's then 32 cars. The line was originally intended to continue above ground, with the current Federico Lacroze station to be the central terminal of the Buenos Aires Central Railway (today the General Urquiza Railway ), however nowadays

After this, it was decided to prioritise the other construction projects in the network. [REDACTED] Line I will run Parque Chacabuco to Ciudad Universitaria with 18 new stations. The route length is 12.6 km. The future of this line (which had

On 2 October 1884, they were granted a concession to build a 47 kilometres (29 mi) railway also pulled by horses from Buenos Aires through open country southwest to Pilar . On 6 April 1888, the line was opened with the name of "Tramway Rural" (rural tramway) to Pilar with a branch to San Martín thereafter. Three years later, in 1891, it was converted to steam and as

1898-565: The 1940s and had become too unsafe to permit continued private operation, and the line was nationalised by Juan Domingo Perón 's government in 1948 and became part of the General Urquiza Railway , one of the several divisions of the state-owned Ferrocarriles Argentinos . By 1951 it was completely rebuilt, new substations were set up, new modern cantilever roofed stations made of reinforced concrete were built and 28 used 1700 series interurban coaches, manufactured by Pacific Electric Railway between 1925 and 1928, were bought. One interesting fact

1971-667: The 2015–2019 period for the Underground at a conference with other South American mass transit operators in Brazil. One of the largest changes to be made during this period was the upgrading of signalling systems on all lines, with the exception of Line E . Lines A and B were to receive Automatic Train Operation systems, replacing their ATS and ATP systems respectively, whilst lines C, D and H were to receive Communications Based Train Control systems. The implementation of these systems

2044-622: The Argentine National Congress, a decision which was ultimately not taken, favouring instead an underground tramway. The first Underground line was opened on 1 December 1913 and was built by the Anglo-Argentine Tramways Company (AATC), which had been given permission to build in 1909. That line was made up of one of the existing sections of Line A , linking the stations of Plaza de Mayo and Plaza Miserere . 170,000 passengers took part in

2117-695: The CHADOPyF lines (C, D and E) had formal connections between them. However, the rate of expansion of the network during this period had slowed considerably and only one station was opened during the 1970s. Four different long-term expansion proposals were put forward between 1964 and 1991 which all proposed adding numerous lines to the network as well as extending the existing ones. Given the political instability characteristic of Argentina during this time, none of these proposals came to fruition, though aspects of them have been incorporated into contemporary expansion plans. One additional proposal put forward in 1973 saw

2190-401: The Law 670 plan. [REDACTED] Line H 's extensions to the north from Corrientes to Plaza Francia, serving intermediate stations at Córdoba, Santa Fe and Las Heras, and south from Hospitales with stations at Nueva Pompeya and Sáenz, were initiated with ground-breaking ceremonies on 17 January 2012. Since then, following concerns that the construction of Plaza Francia station would damage

2263-549: The Subte, regardless of travelled distance. After 20 trips, the fare is discounted 20%; after 30 trips, 30%, and after 40 trips the fare is discounted 40%. The Premetro has a flat rate of AR$ 43.75. Fares have been increased multiple times due to devaluation of the Argentine Peso. While tokens have been used in the past, at present riders use contactless cards called SUBE , which are rechargeable with multiple forms of payment. Previously, single or multi-use paper cards with

2336-582: The Underground system as part of Line B and operated by the Underground operator Metrovías . As a result, it has similar characteristics to Line B, using third rail electrification and standard gauge as opposed to the broad gauge used in the Buenos Aires commuter rail network. It runs from the Federico Lacroze terminus in the barrio of Chacarita , to General Lemos terminus, Campo de Mayo in Greater Buenos Aires . The line

2409-469: The capital expanded, business to the suburbs was so good that a new branch to Campo de Mayo was inaugurated in 1904 using electric power supply, and the whole section between Federico Lacroze and San Martín was electrified in 1908. Electricity came from the Lacroze tramways of Buenos Aires and overhead wires delivered 600 volt DC current to a fleet of wooden US-style interurban coaches from Brill . In 1897

2482-415: The central station of the General Urquiza Railway and terminus of the [REDACTED] Urquiza Line suburban electric commuter line operated by the underground operator Metrovías . Originally, the underground station was intended to be the central terminal for Federico Lacroze's Buenos Aires Central Railway , however years later when construction of Line B began, it became an underground station. When

2555-610: The city administration the power to license building in the city's subsoil and for this reason, subsequent drafts were submitted directly to this ministry. In 1894, when it was decided to construct the Congress building in its present location, the underground idea was revived, since it would shorten the travel time between the Casa Rosada and the Congress. In 1896 Miguel Cané, former mayor of Buenos Aires (1892–1893), expressed

2628-484: The city and is said to be overcrowded. As of 2015, two modernisation plans have been presented: City of Buenos Aires law 670, proposing the creation of 3 new lines (F, G, and I), and the PETERS plan, wherein 2 lines are created and the I line is postponed for future expansion, plus several other route amendments. Since 2019, there are no expansions under construction, for the first time in half a century. The entire network

2701-459: The city centre. The new lines will mean that more than two million inhabitants of Buenos Aires (accounting for about 70% of the city centre's population) will live within 400 metres of a metro station. The new lines will run between 56 new stations. [REDACTED] Line F will run from Barracas to Plaza Italia in Palermo and will include 16 new stations. The planned route length of this line

The Line A stations – Pasco Sur and Alberti Norte – were closed in 1953 since stations in that part of the line were grouped very closely together and having fewer stops improved the line's frequency. Pasco Sur remains in very good condition, while Alberti Norte

2847-474: The early decades of the 20th century; by 1944, its main routes were completed, with the addition of its newest line occurring as late as 2007. The pace of expansion fell sharply after the Second World War . In the late 1990s, expansion resumed at a quicker pace, and four new lines were planned for the network. Despite this, the network's expansion has been largely exceeded by the transportation needs of

2920-547: The end of 2015, the Intendente Saguier terminal had been refurbished, though other works on the line were delayed. The Premetro was originally intended to include a number of feeder lines to the Underground network, including a second one to Line E and ones on lines C and D . The Premetro project was largely abandoned since it occurred in Argentina's transition to democracy from the military junta and then

2993-603: The entire line and up-dated electrical components. In the meantime, it is still possible that the rebuilding of the existing ramp at Federico Lacroze underground station would allow connection to Line B , enabling trains to run through to the centre of Buenos Aires, a dilemma which is uncertain at this moment, simply because the UTA (Unión Tranviarios Automotor , in English; Tram Drivers' Union) and Rail Unions are not compatible with each other and therefore do not agree on it. When

3066-654: The expected increase in passenger numbers as a result of the connection with Line D began arriving in the country in 2015. The future expansion outlined in Law 670 would see the addition of three new lines. These lines' routes have already been approved by the Legislature of the City in Law 670. 39.3 km will be added to the network, expanding it to about 97 km in total length and providing several stations with various interchanges. This will also create new north–south routes, resulting in an appropriate network to avoid

3139-538: The failure of the PETERS plan to account for the extension of the Belgrano Sur Line to Constitucion railway station , meaning that Line C's extension to the minor Buenos Aires terminal would be redundant, and that the Retiro Norte node would also be made redundant by the planned Red de Expresos Regionales commuter rail tunnels which are to link the three major railway terminals of the city. Much of

3212-405: The line was renamed Ferrocarril Rural de la Provincia de Buenos Aires (Buenos Aires Province Rural Railway) and in 1906 it was renamed again to Ferrocarril Central de Buenos Aires ( Buenos Aires Central Railway ). However, since it was still operated by its owners, it continued to be known unofficially as the " Federico Lacroze Rural Tramway ". The original cars were still running by the end of

3285-623: The line's first trip. On 1 April 1914 the line was to expand to Río de Janeiro station and on 1 July was extended to Primera Junta Station. In 1912, the Lacroze Hermanos company won a concession to build another Underground line. The company was a competitor to the Anglo-Argentine company, operating tramways in Buenos Aires as well as the Buenos Aires Central Railway , which later became part of

3358-563: The lines while they are closed. The Subte operations are radio-controlled and monitored remotely from the Metrovías Central Operations Post (PCO in Spanish). There 24 operators have been monitoring four of the six subway lines (lines C and H have separate monitoring) since 2001. As of 2015, last formations arrive at their respective terminals at approximately 11:30 pm, where maintenance and cleaning operations take place until about 4:00 am. The PreMetro line E2

3431-808: The lowest priority in the expansion plans) is currently uncertain since it has been proposed that a Metrobus line be built instead, which would follow the same trajectory as the line. In October 2015, the city of Buenos Aires together with the Inter-American Development Bank presented a 150-page plan for the Underground called the Strategic and Technical Plan for the Expansion of the Subterranean Network ( Plan Estratégico y Técnico para la Expansión de la Red de Subtes , or PETERS), highlighting past expansion efforts and

3504-427: The modernisation in recent years has centred around the Underground's rolling stock , with large scale renewals and refurbishments of existing fleets, in particular on Lines A and H. Along with this came the construction of new underground workshops and storage areas on lines A, H and E, as well as the expansion of the existing facilities on Lines B and D. In September 2015, the president of SBASE highlighted plans for

3577-444: The most crowded in the world by Google based on crowdedness reports by its users. Buenos Aires Underground The Buenos Aires Underground (Spanish: Subterráneo de Buenos Aires ), locally known as Subte ( Spanish: [ˈsuβte] ), is a rapid transit system that serves the area of the city of Buenos Aires , Argentina. The first section of this network (Plaza de Mayo–Plaza Miserere) opened in 1913, making it

In this version of the Underground, Line I is cancelled while Line G takes a different route through the centre of the city terminating at Constitucion railway station after going through the neighbourhood of San Telmo , rather than through Retiro railway station . Other changes include a Retiro Norte node where lines F and H terminate, rather than at Plaza Italia and Retiro respectively, while Line E

3796-733: The need to build an underground railway similar to the one in London There were numerous proposals at the time to build an electric aerial tramway , with one such line to go down the Avenida de Mayo . One proposal was the 1889 Le Tellier proposal, which envisioned multiple lines running along the city's wider avenues with the trams moved using cables and would hang from steel rails fixed to 6-metre-high (20 ft) steel and iron posts positioned in 10-to-15-metre (33 to 49 ft) intervals. The lines would take 24 months to build, and construction would commence 3 months after their approval by

3869-462: The network's signage to match the new schemes. In 2012, the role of Metrovías was lessened to simply operating the lines, while maintenance of infrastructure became the responsibility of SBASE. The relationship between Mauricio Macri 's mayoral administration and Metrovías became increasingly strained, with the Government of Buenos Aires issuing multiple fines to the operator. The relationship

3942-400: The network, its rolling stock , and infrastructure, and administers its expansion and budget. One cosmetic change carried out in the 1990s under private operation was the re-assignation of the colours of the lines, with Lines B and D switching colours, Line C changing from purple to blue and Line E changing from yellow to purple. The change of colours was also accompanied by a standardisation of

4015-710: The order in which the lines were opened. In 1952, the CTCBA was absorbed by the Buenos Aires Transport General Administration (AGTBA), and in 1963, the administration was dissolved and the underground network became the property of the Subterráneos de Buenos Aires company (SBA). In the early years of nationalisation, interchanges were provided between the lines previously belonging to the three different companies that built them (AATC, CHADOPyF and Lacroze) since previously only

4088-541: The overground service forms part of the Urquiza Line instead. By the 1920s, the Argentine government was dissatisfied with the lack of progress the AATC (which enjoyed a near-monopoly on the city's tramways by this point) had made in expanding the rest of the network and thus revoked its right to build any more lines in 1930, seeking instead another company to do so. By this point, the AATC had only built 48 metres of what

4161-615: The privatisation of the railways , which was a difficult time economically for the country, and only Line E2 was built. New Premetro feeder lines have been proposed in recent years, however, the role of the network has given way to the new Metrobus network which covers many of the same routes originally intended for the Premetro. Línea Urquiza (in English: Urquiza Line) is a 26-kilometer (16 mi) suburban electric commuter rail line originally designed to be part of

4234-552: The property of the City of Buenos Aires. In December 2021, "Emova Movilidad S.A." took over the concession of the Buenos Aires Underground for 12 years. Emova is also part of the Roggio Group, associated with former operator Metrovías. The Subte opened in 1913, becoming the 13th underground system in the world, as well as the first in Latin America , the Southern Hemisphere and the Hispanophone world, followed by

4307-480: The replacement of 14 km of track on Lines C and E. The total investment in this period for these new projects was set at US$ 1.34 billion. Federico Lacroze (Buenos Aires Underground) Federico Lacroze is an underground station on Line B of the Buenos Aires Underground named after the Argentine railway entrepreneur , located at the intersection of Corrientes and Federico Lacroze avenues in

4380-447: The station platforms were raised at the same time to match the new coaches. Companies that have operated the Urquiza Line since it was established after the 1948 nationalisation are: The number of passengers carried by the Urquiza Line has increased steadily in recent years and several improvements have been made, including adapting stations for the disabled, grade crossings improvements, new concrete sleepers and welded rail joints for

4453-496: The system was in a crisis exacerbated by the monopolisation of the lines, which had concentrated under the ownership of fewer companies during the electrification of the system. In this context, the first proposals for the building of an underground system were made, along with requests for government grants: first, in 1886, and several more in 1889. However, the Ministry of Interior ( Ministerio del Interior , in Spanish) denied

The entire network was centralised and nationalised in 1939 under the management of the Transport Corporation of Buenos Aires (CTCBA) and the lines were given their current lettered naming scheme, from A to D in

4599-490: The unification of the city's commuter rail lines through tunnels and incorporated into the Buenos Aires Underground, and while this was also shelved, it was included in the Red de Expresos Regionales proposal. During the 1960s and 70s, efforts were primarily concentrated on Line E, which was re-routed from its terminus at Constitución to the centre of the city at the Plaza de Mayo in an attempt to boost passenger figures, something which proved to be successful. The segment

4672-482: The western termini of Lines D and E as well as one in Puerto Madero , however only Line E2 was completed in 1987 and these plans were scrapped in 1994 when operation of the Underground changed hands. In 1994 the operation of the network was privatised , along with the country's railways , and is now managed by Metrovías . SBASE (as part of the Government of the City of Buenos Aires) maintained ownership of

The Subte then entered into a concession model in the mid-1990s through which private sector parties were to submit bids to execute investment plans "designed and funded" by the state, while implemented by the concessionaire. All the Underground lines, along with

Line D was also to receive platform screen doors along with the CBTC system. Other works to be carried out during this period include the improvement of disabled access in older stations, new ventilation systems on lines B, C and D, improvements in electrification (such as replacing overhead lines and substations) on lines A, B, C and D and

4891-468: Was considered that the two former Line E stations and tunnels should be used for Line F since the line's southern terminus would be there and that part of the route would be roughly similar to the old Line E. However, it was eventually decided that the line should use new tunnels in that section due to its sharp curves. There have been several plans to expand the Underground system as a whole. The Underground's routes are said to spread out like "branches of

4964-491: Was converted into an electrical substation. The Line E stations were closed in 1966, after the line was re-routed from Constitución railway station (where it connected with Line C ) closer to the centre of the city, leaving the San José vieja and Constitución stations out of the network, a move which tripled traffic on the line. The two stations have subsequently been used as workshops and storage areas. At one point it

Among the public, privatisation has proved unpopular, with a survey carried out in 2015 indicating that 82% of passengers would like the Underground to be operated by the state instead of a private company.
