If anybody is planning to use this train, then I would recommend that you pick up the latest timetable (05) from the station. I printed off a timetable before I left last week, which was supposed to go up to the end of December 2013, but it was replaced on 25 August 2013 by a new version. I'm not sure how much has changed, but certainly the trains back to Nice from Peille in the afternoon are different.
The timetable displayed in the window of the ticket office in Peille (which was closed) was the out of date version! The new timetable is, however, displayed on the platform. Very confusing!
