The tracks that Transilien Line V operates over were built as part of the

A large part of the Grande Ceinture line was closed to passenger traffic in 1939 with the exception of the southernmost section of the future line V, between Versailles-Chantiers and Juvisy via Massy-Palaiseau. However, the majority of trains over the line were freight trains.

This section of the line was electrified on 6 February 1947. Additional passenger traffic would come to the line over the following decades until the line was integrated into the RER C line of the Réseau Express Régional in 1992.

In 2004 and again in 2008, studies were conducted into adding more frequent service on the line, first proposing it become a dedicated RER line, then later recommending it become a tram-train line. However, the section between Versailles-Chantiers and Massy-Palaiseau chosen for conversion, instead focusing on the section between Massy-Palaiseau and Épinay-sur-Orge.

On June 7, 2023, the president of Île-de-France Mobilités, Valérie Pécresse announced that the section of between Versailles-Chantiers and Massy-Palaiseau would be disconnected from the RER C network to be operated as separate shuttle line. The disconnection took place on 10 December 2023, the same day the T12 Express tramway line started operating between Massy-Palaiseau and Épinay-sur-Orge.
