Seventy-five of these 4-car units were built for use on suburban service in the west of Paris, operating mainly on the Transilien Line L. The 4-car units were most often used in double-formation as 8-car sets. 43 sets had doors arranged for high platforms, while the remainder were for low platforms.^[1][2]

They were progressively replaced by the Class Z 50000 units with the last commercial service of the Z 6400 running on 4th November 2020. This was earlier than originally scheduled due to a downturn in passengers numbers during the COVID19 pandemic.^[3][4][1]
