Grenoble

The Ligne de Grenoble - Montmélian is a 50 km long railway in southwest France. It was built by the PLM and opened on 15 September 1864 (as a double track) to provide a link between Grenoble and Montmélian.^[1] In September 1991 it was electrified between Grenoble and Gières and electrification of the whole line is planned ^[2].

In the past the line took a route more north, closer to the centre of Grenoble. However, as part of the city's preparations for the 1968 Winter Olympics, the route was mooved south, next to the Rocade Sud. This added about 3km to the total length of the track, so to not have the laborious task of changing all the milestones along the route, this new section was given distances as if it were part of the Ligne de Lyon - Grenoble, all the while staying part of this line. A part of the old line is still existent at 45°10′46.10″N, 5°43′12.16″E.
