Buenos Aires Underground 100 Series
The 100 Series are a series of underground railway cars manufactured by Alstom in Brazil and Argentina for use on the Buenos Aires Underground. They are used on Line D of the network, where they make up the vast majority of the fleet, serving alongside some 300 Series and Fiat-Materfer cars. Since 2019, some units have also been used on the Line E. History The 100 Series was initially purchased for use on Line A to replace the ageing La Brugeoise cars, however they ended up replacing the slightly newer Siemens-Schuckert Orenstein & Koppel cars which were allocated to Line D instead. Originally, the purchase consisted of 80 cars for a total of 16 trains made up of 5 cars each, due to the shorter platform length on Line A. However, 16 more 100 Series cars were purchased up until 2009, making a total of 96 cars and allowing each train to have 6 cars, making full use of the line's platforms. In 2015 the cars began to receive a mid-life refurbishment, primarily to add air co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Line D (Buenos Aires Underground)
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. History Line D was the second line to be built by the Compañía Hispano Argentina de Obras Públicas y Finanzas (CHADOPyF, Hispanic-Argentine Company for Public Works and Finances), following the construction of Line C in 1934. Construction began in 1935 and the first part of the line was inaugurated in 1937 and ran 1.7 km from Catedral (still the current terminus) to Tribunales. Three years later, the section which brought the line to Plaza Italia in Palermo was completed, bringing the length of the line to 6.5 km. The line was not properly extended until 1993 when it was extended to Ministro Caranza, a station named after the Radical politician. Further extensions occurred in t ...

Line E (Buenos Aires Underground)
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. History Line E was opened on 20 June 1944, after construction began in 1938, with an original route that ran from Constitución railway station to General Urquiza. Soon after, it was decided to abandon the terminus at Constitución (which also served as the connection with Line C) and instead reroute the line towards the Plaza de Mayo. Work began in 1957, and in 1966 the San José, Independencia, Belgrano and Plaza de Mayo (now Bolívar) stations were opened to the public by president Arturo Umberto Illia. For many years, the two stations that had been closed as a result of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Buenos Aires Underground 200 Series
The 200 Series is a set of underground cars manufactured by China CNR Corporation and CITIC Construction for use on Line A of the Buenos Aires Underground in Argentina. The cars replace the 100-year-old La Brugeoise cars which operated on the line up until 2013. The Buenos Aires Underground ordered 45 of these units, followed by a further 105 which have been put into service on the line. Background and overview Since the opening of Line A in 1913, it had used the same La Brugeoise et Nicaise et Delcuve rolling stock (along with a small number of UEC Preston cars at one point). Over the years, numerous attempts were made to replace the rolling stock on the line, though this proved challenging due to its tight curves and use of 1100 volts current instead of the 1500 volts used on the rest of the network. One such attempt was the Alstom Metropolis cars purchased at the turn of the 21st century, however these ultimately ended up serving on Line D. Before then, an attempt at cr ...

Buenos Aires Underground Rolling Stock
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. History Before the nationalisation of the railways and the formation of ''Subterráneos de Buenos Aires'', the original lines of Buenos Aires Underground were built by three private companies, and each bought different rolling stock for their lines. Line A was inaugurated in 1913 by the Anglo-Argentine Tramways Company (AATC)—then owned by the Belgian company Sofina—who owned the vast majority of the city's tramways at that point. Two companies competed to provide the rolling s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Air Conditioning
Air conditioning, often abbreviated as A/C or AC, is the process of removing heat from an enclosed space to achieve a more comfortable interior environment (sometimes referred to as 'comfort cooling') and in some cases also strictly controlling the humidity of internal air. Air conditioning can be achieved using a mechanical 'air conditioner' or alternatively a variety of other methods, including passive cooling or ventilative cooling. Air conditioning is a member of a family of systems and techniques that provide heating, ventilation, and air conditioning (HVAC). Heat pumps are similar in many ways to air conditioners, but use a reversing valve to allow them to both heat and also cool an enclosed space. Air conditioners, which typically use vapor-compression refrigeration, range in size from small units used within vehicles or single rooms to massive units that can cool large buildings. Air source heat pumps, which can be used for heating as well as cooling, are becoming incre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Siemens-Schuckert Orenstein & Koppel
The Siemens-Schuckert Orenstein & Koppel (normally abbreviated to Siemens O&K) 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 (with the exception of Line B, which uses third rail electrification) from 1934 to 2016, with cars refurbished by the Emepa Group and Alstom continued to function on the network till 2017. As such, it has been the most widely used rolling stock in the Underground's history, and second only to the Brugeoise cars in the number of years served, being the oldest cars in circulation at the time of their retirement in 2016. History The first Siemens-Schuckert Orenstein & Ko ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
La Brugeoise Cars (Buenos Aires Underground)
''La Brugeoise cars'' were Buenos Aires Underground (''Subte'') Line A rolling stock since its inauguration in 1913 till 2013 when replaced by new Chinese stock. They were built by the Belgian railway rolling stock manufacturer La Brugeoise et Nivelles between 1911 and 1919 for the Anglo-Argentine Tramways Company's (''Compañía de Tranvías Anglo-Argentina'' (CTAA) in Spanish) first underground line. They were originally designed to run both as metro and tramway cars, but they were refurbished in 1927 for underground use only. They became the oldest underground rolling stock in commercial service in the world as well as a tourist attraction and part of Buenos Aires cultural heritage. Technical information The La Brugeoise trains were designed to run using either 550 VDC (as surface tramways did until the system was closed in 1962) or 1,100 VDC in the tunnels. Traction was controlled through a 9-power run (originally 11-power run) handle, known as the "controller". Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Line A (Buenos Aires Underground)
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. On the first day of public service (18 December 1913), it carried 220,000 passengers.Subterráneos de Buenos Aires (Official Page) History of Line A – Retrieved 2010-11-04 Line A used the |
Fiat-Materfer (Buenos Aires Underground)
The Fiat-Materfer Buenos Aires Underground rolling stock was built by the Argentine company Materfer - then a subsidiary of Fiat Ferroviaria - beginning in 1980 and continuing on through that decade. It was originally conceived to standardise the diverse rolling stock of the Buenos Aires Underground with the use of one model throughout all the lines. However, with the economic and political turmoil faced in the country during and following the collapse of the National Reorganisation Process junta in 1983, its production ended up being far more limited. During the 2010s, the cars were used as temporary stock for two lines, being phased out as newer models arrived from overseas. History and overview By the late 1970s, the Buenos Aires Underground had a vast array of ageing rolling stock. This was because the different lines were developed by different companies in different periods. Yet the need for standardisation was becoming apparent given the increased cost of dealing with so ...

Buenos Aires Underground 300 Series
The 300 Series are a set of underground cars manufactured by Alstom in Brazil for use on the Buenos Aires Underground. They are used on Line H of the network, and more have been introduced on Line D where they operate alongside the similar 100 Series. History The 300 Series cars were initially ordered for Line H in 2012 with an initial order of 120 cars at a cost of US$ 216 million. These were to be delivered in 2015 and produced solely in Alstom's plant in São Paulo, unlike the 100 Series which also had components produced in Argentina. These were to be put into service once the Córdoba, Santa Fe and Las Heras stations were opened. On Line H, the cars replaced the Siemens-Schuckert Orenstein & Koppel cars which had served on every line of the system, with the exception of Line B, at different times since 1934. When Line H was originally opened, it was not deemed necessary to purchase new stock until it had been extended enough and passenger numbers were at a level whe ...
