Grande ceinture Ouest
The Grande ceinture Ouest line is a 10km long section of the Grande Ceinture de Paris, located in Yvelines and reopened to the public on 12 December 2004, after being closed to passengers for 68 years. Managed by the SNCF, it links Saint-Germain-en-Laye to Noisy-le-Roi, via Saint-Nom-la-Bretèche. The line is little used at the moment but nevertheless provides a window on the SNCF via the many innovative methods used on it.
