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. [1]
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. [2]
In 2015, the cars began to receive a mid-life refurbishment, primarily to add air conditioning, but also incorporating enhancements to the interior. This included improved lighting and new upholstery. [3] Despite enjoying a successful service life, they are also the noisiest cars on the network. [4]
Between 2017 and 2019, New Alstom 300 Series cars replaced the Fiat-Materfer cars and served alongside the existing 100 Series cars. [5] By 2022, Almston has signed three new maintenance contracts in Argentina to ensure the safety and accessibility of the transit's track, signal systems, tunnels, bridges, vehicles, and stations. [6] The project is expected to take 19 months, with its operation set on Line E once completed. [7]
