all stations are accessible The Trans-Val-de-Marne, often abbreviated as Tvm, is a bus rapid transit (BRT) line operated by the RATP Group as part of the RATP bus network in the Paris metropolitan area.

The line entered service on 1 October 1993, running almost entirely in a dedicated lane.

It replaces the former RATP line 392, which since 1969 has linked Saint-Maur–Créteil station and Rungis.

The Tvm connects Saint-Maur–Créteil to La Croix de Berny, serving thirty-two stations over nearly twenty kilometres (12 mi).

[1] It is the busiest bus line in Europe, with 23 million passengers in 2019.
