Due to the current weather conditions and a high risk of avalanches, travel between Châtelard-Frontière and Chamonix is strongly discouraged.

We recommend that you cancel or postpone your journey until further notice.

Thank you for your understanding.

In order to modernise our infrastructure and prepare the new TMR station in Martigny, major works will take place between November 2025 and March 2026.

The Martigny – Vernayaz MC section will be completely closed from 17 November 2025 to 29 March 2026.

Throughout the closure, replacement buses will be in service and parking spaces will be available in Vernayaz.

Trains will run as normal on the rest of the line.

Bus timetables correspond to the usual train timetables to make your journey easier.
