The CSR EMU is a series of electric multiple unit cars manufactured by CSR Corporation Limited for use on Buenos Aires' commuter rail network. The trains operate on three of the city's lines as of 2015 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.
By 2013, the of Buenos Aires' commuter rail network was ageing and deteriorating rapidly. At the same time, high-profile accidents in Flores and Once in previous years had led the national government to revise the concession-based railway privatisation, which was largely blamed for the deterioration of the network. The government thus decided to intervene, revoking concessions to companies such as Trenes de Buenos Aires and setting up Trenes Argentinos to manage the lines.
This was followed by a series of rolling stock purchases from China CNR Corporation and CSR Corporation Limited (and later some Argentine companies) to replace trains on both diesel and rail segments. For the electrified lines, CSR won the contract to provide the electric multiple units, and an order was placed in January 2013 for 405 cars for the Mitre and Sarmiento lines, with another order for 300 cars for the Roca Line signed in August of that same year.
The acquisition of the CSR rolling stock was also accompanied by a series of works on all three lines, both to accommodate the new trains such as with the electrification of the Buenos Aires - La Plata segment on the Roca Line, but also general improvements. On top of the emergency improvements undertaken following the Once Tragedy, some of these improvements included the modernisation of stations, raising the height of platforms to match the new trains, incorporating train protection systems, creating new underpasses and rail infrastructure improvements, some of which were also undertaken by the City of Buenos Aires. However, not all works were finished by the time the CSR EMUs arrived on their respective lines, and some works continued on while they were already functioning.
