Buenos Aires Underground rolling stock

inside the Polvorín Workshop in 1913. car on Line B. rolling stock at Constitución station on Line C. cars were the first attempt at standardisation. 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 stock of the line: the Belgian La Brugeoise et Nivelles and British United Electric Car Company, with the Belgian company ultimately winning the contract. However 4 UEC Preston cars had been sent to the country and these more extravagant cars were kept in service on the line until the 1970s and were often used on special occasions. The Brugeoise cars made up the entirety of the rolling stock of the line until 2013, retiring just before their 100-year anniversary. The Argentine company Lacroze Hermanos built Line B, originally designed to be an underground continuation of the Buenos Aires Central Tramway (today the Urquiza Line). The line has historically been significantly different from the others in terms of rolling stock since it uses third rail electrification instead of overhead lines and as such, it has been the most troublesome to standardise and has often had the most diverse rolling stock, with four different models circulating on its tracks at one point. Originally served by Metropolitan-Cammell cars from its opening in 1930, these were later reinforced by cars from the Osgood Bradley Car Company in the 1950s. Later on, two attempts were made by the state-owned Fabricaciones Militares to replace the rolling stock of the line, however these were never produced in enough numbers to replace all the cars on the line. It was only in 1996 that the line was standardised again when cars were bought second-hand from the Tokyo Metro Marunouchi Line in order to replace all the cars. This was also the first time in the history of the network that cars were bought second-hand. Lines C, D and E were all built by the Hispanic-Argentine Company for Public Works and Finances (CHADOPyF) in the 1930s and 1940s and were thus the most straightforward. All the lines used German Siemens-Schuckert Orenstein & Koppel rolling stock from their inaugurations, though during the 1960s Spanish-built CAF-General Electrica Española were added to the lines. The CAF-GEE cars were designed to be highly compatible with the Siemens-Schuckert Orenstein & Koppel cars in order to reduce maintenance costs. It was only in the 1980s that the rolling stock started to diversify on these lines when Fiat-Materfer cars began to be introduced in order to standardise all the lines of the network (with the exception of Line B) using this rolling stock, however not enough of these were built to replace the Brugeoise, CAF and Siemens cars, so the ended up being spread thinly and switched between lines as temporary stock since their introduction. In December 2013 a law was passed which meant that the entire La Brugeoise fleet would receive protection status and would thus only be donated to organisations dedicated to their restoration and preservation. The three surviving UEC Preston cars serve on the Buenos Aires Heritage Tramway above-ground in the neighbourhood of Caballito. Two Siemens-Schuckert Orenstein & Koppel also have been donated to the Buenos Aires Heritage Tramway, but the fate of the rest of the fleet is still unclear. On 1 February 2018, the Buenos Aires Heritage Tramway received a donation from SBASE consisting of a Metropolitan Cammell and a Siemens-Fabricaciones Militares. ==Current fleet==

In the mid-2010s, the Underground was in a transitional period where temporary rolling stock was serving on numerous lines while orders arrived from China and Brazil. After these cars arrived in 2015 and 2016, the network had a far less diverse rolling stock, with Line A being composed entirely of CITIC-CNR trains, while lines D and H were made up entirely of Alstom Metropolis trains. The older Siemens-Schuckert Orenstein & Koppel cars were completely retired from the network, thus reducing the average age of the rolling stock significantly. With this move towards standardisation, some of the newer trains have received series numbers: the original Alstom Metropolis trains on Line D have been dubbed the 100 Series, the CITIC-CNR trains are the 200 Series, while the newer Alstom Metropolis trains for lines H and D are the 300 Series. Line B are composed of CAF cars purchased from the Madrid Metro while retiring the Eidan 500 cars. Line C is using a variety of Nagoya cars, while Line E is using Fiat-Materfer cars and refurbished Siemens-Schuckert Orenstein & Koppel cars, retiring the CAF/GEE cars. No plans have been made public about the long-term intentions with these lines, though Line C has received a modern communications-based train control system in preparation for newer rolling stock. It has not been stated what rolling stock will be used on Line F, though the usage of platform screen doors on the line will require modern rolling stock and automated trains are being considered. Line A car. Until 2013, Line A had been served by La Brugeoise cars and a small number UEC Preston cars, which were retired prior to the Brugeoise cars. These were withdrawn from service on 12 January 2013, 11 months before their 100th anniversary and replaced by 45 new 200 Series cars built by China CNR Corporation. However, the Chinese cars were not sufficient to cover the entire fleet of the line, so it had to be supplemented by a temporary fleet of 35 Fiat-Materfer cars, which was still not enough to replace the 120 La Brugeoise units and thus Siemens-Schuckert Orenstein & Koppel stock reformed by the Emepa Group was also added to the line to make up the numbers. Furthermore, the replacement of the rolling stock coincided with the opening of the San José de Flores and San Pedrito stations and the line was still left with a rolling stock defect, causing a decline in passenger numbers. A further 105 CNR cars were ordered in 2014 so that the line would be served in its entirety by 150 of these 200 Series cars, and so the temporary replacement rolling stock could be moved to Line E in time for its extension to Retiro. The cars steadily arrived into the country since 2015 and have been incorporated into the line, with the last of the CNR units arriving during 2016 and 2017. Line A's rolling stock now consists entirely of these models. Line B . train Line B has been historically the most diverse of the network given its significantly different characteristics to other lines and thus its rolling stock has not been uniform for most of its history. This was addressed in 1996 when rolling stock was purchased from the Tokyo Metro Marunouchi Line in order to make the line uniform. This was also the first time in the network's history that rolling stock was purchased second hand. In 2003, two stations were added to the line, followed by another two in 2013, meaning that the already old rolling stock was now also stretched to capacity. In 2011, it was announced that the Madrid Metro had sold some of its 5000 series trains to the Underground, which had been in operation in Madrid since 1974, and entered service in 2013 in order to make up shortfalls caused by the line's extensions. The 36 Spanish cars were of lower quality and reliability than the Japanese trains, despite being newer, and suffered a series of mechanical issues following their integration into the line. A further 13 of these cars were purchased for $7.8 million, bringing the total up to 86. The biggest drawback of these cars is that, unlike the Eidan 500 and CAF 5000 cars, they use overhead electrification instead of third rail, and were thus initially unsuitable for the line. They had to be adapted to use both third rail and overhead electrification for what was by this point three models of rolling stock being used on the line. Line C Line C was originally served by Siemens-Schuckert Orenstein & Koppel rolling stock, which were replaced in 2007 by Nagoya rolling stock transferred from Line D as 100 Series cars arrived on that line. These cars began to be refurbished in 2014, equipped with air conditioning, new lighting and upholstery, among other changes. The refurbishment of the 78 Nagoya cars was completed in 2015–2016. From 2014, 30 additional cars, belonging to the newer 5000 Series, were purchased from the Nagoya Municipal Subway and arrived in the country. With the incorporation of these trains in 2015, the line has 108 Nagoya cars, though from different series and refurbished to increase the uniformity among them. No long term plans have been made as to what rolling stock the line will use when it is modernised, however the line has been updated with Trainguard Communications-based train control to allow for automatic train operation, meaning that it could be served by such trains. In early 2016, the final figure had been fixed at 60 new cars. By 2017, the fleet was composed of 156 Alstom Metropolis cars, retiring the Fiat-Materfer cars from the line. In June 2017, the first six Alstom 300 started operating in the line. After the project to add CBTC to the line in 2024, Line D's fleet was made up of exclusively Alstom 300 cars, with the Alstom 100 cars previously assigned to the line were overhauled and transferred to Line E. Line E The line was the last to be inaugurated with Siemens-Schuckert Orenstein & Koppel rolling stock, however these were replaced by Fiat-Materfer cars in the 1980s. The Materfer cars were later sent to Line D and Line D's CAF-GEE rolling stock was put to use on Line E, where it remains until this day, making up the entirety of the rolling stock on the Line. After the new 200 Series and 300 Series rolling stock arrived for Lines A, D and H and the three lines are composed entirely of these two models, the CAF-GEE rolling stock has been retired from Line E and replaced once again with Materfer since the refurbished Siemens by Alstom and the Emepa Group were more than 80 years old and their performance was poor. This change occurred before the completion of the line's extension to Retiro. Today, the line continues to use its Materfer cars, as well as refurbished Alstom 100 cars displaced from Line D. Line H car. When Line H was opened in 2007, its short length meant that it could be temporarily served by Siemens-Schuckert Orenstein & Koppel cars until it was extended enough to warrant the incorporation of new rolling stock. For this purpose, 120 new Alstom Metropolis 300 Series cars were ordered from Brazil and began arriving in Buenos Aires in August 2015 in time for the line's extension northwards to Santa Fe. The first 300 Series cars were put into service in July 2016, with the remainder being phased in throughout 2016 and 2017, increasing frequencies to an average of 3 minutes as a result of the increased number of trains as well as the use of Communication Based Train Control (CBTC). The incorporation of these cars also meant the retirement of the Siemens-Schuckert Orenstein & Koppel cars, which were the oldest serving stock on the network. PreMetro When the Premetro was opened in 1987, it was to be served by trams manufactured by the Argentine company Materfer. However, the cars were not ready for the line's inauguration, so it was briefly served by La Brugeoise cars re-bodied by the Emepa Group. The re-bodied cars were nicknamed Lagartos (Lizards) due to their green colour and were soon retired. In 1988, the Materfer trams arrived on the line and the cars continue to serve on it to this day. Originally, 25 cars were to be built since there were to be two Premetro lines, however, only of these 17 cars were built for the E2 line since the E1 line was not built. Future lines Three other lines are planned for the network, however the only line which has been approved for construction as of 2015 is Line F. Construction was due to begin in 2015 so it is yet unknown what rolling stock will be used, though they will be of modern characteristics, with platform screen doors and automated trains being considered. ==See also==
