The 100 Series represents a collection of subway cars produced by Alstom in both Brazil and Argentina specifically for the Buenos Aires Underground. These vehicles are mainly assigned to Line D, where they make up the bulk of the line's fleet, operating in conjunction with 300 Series and Fiat-Materfer trains. Since 2019, several units have also been deployed on Line E.
History
Originally, the 100 Series was acquired to replace the outdated La Brugeoise cars on Line A. However, they ultimately took over from the more recent Siemens-Schuckert Orenstein & Koppel trains on Line D. The initial purchase included 80 cars arranged into 16 trains of five cars each, constrained by the platform lengths on Line A. By 2009, an extra 16 cars were added, allowing trains to be extended to six cars and thus maximizing platform utilization.
A refurbishment program began in 2015 aimed at mid-life upgrades, which involved installing air conditioning and enhancing interior features such as lighting and seat fabrics. Despite these improvements and their long service life, these trains are still considered the loudest within the network.
From 2017 through 2019, newer Alstom 300 Series trains replaced the Fiat-Materfer models but continue to share operation with the 100 Series. In 2022, Alstom obtained three maintenance contracts in Argentina that cover various infrastructure components including tracks, signaling systems, tunnels, bridges, rolling stock, and stations. This extensive project spans 19 months and will prioritize operations on Line E upon its conclusion.
