SNCF Class Z 6400

The SNCF Class Z 6400 electric multiple unit trains were built by Alsthom with Carel et Fouché from 1976 to 1979. They were chiefly used in commuter service to the Gare Saint-Lazare in Paris, serving the northwest Paris suburbs. Seventy-five of these four-car units were built for suburban service in the west of Paris, operating mainly on Transilien Line L, and they were most often used in double formation as eight-car sets, with 43 sets having doors arranged for high platforms and the rest for low platforms. They were progressively replaced by the Class Z 50000 units, and the last commercial service of the Z 6400 ran on 4 November 2020, earlier than originally scheduled because of a downturn in passenger numbers during the COVID-19 pandemic. A related version, the CPTM 5000 and 5400 series, was manufactured by the Cobrasma-Francorail consortium in the late 1970s for the Paulista railway in the São Paulo area.
