Inauguration: the T12 tram-train runs between Massy and Évry-Courcouronnes

The T12 is the new tram-train that connects Massy to Évry-Courcouronnes in 16 stations. It opened its doors on December 10, 2023, after three months of dry run.

What is a tram-train?

The tram-train is a 2-in-1 tram that runs both on conventional tram tracks, in urban areas, and on the tracks of the national rail network. The T12, for example, uses it between the stations of Massy and Petit Vaux, which it now serves instead of the RER C.

T12 tram-train: improving service to Essonne and access to the region's business and employment centres

Accessible and fast, the T12 tram-train line facilitates travel in the department (twelve municipalities in Essonne are served) as well as between the various centres of activity and employment in the area thanks to connections with the rest of the regional network (RER B, C, D, bus lines, the Tzen 4 and, eventually, the metro 18).
