Among other things, this did not proceed because the canton of Valais required two connecting lines, one between Martigny and Sion and one between Illersaz and Le Bouveret.

An application submitted a year later for a line from Le Bouveret to Sion, however, was successful and received a federal concession.

Passenger traffic is limited to hourly regional trains operated by RegionAlps.

Various sidings in Monthey and Collombey serve daily freight traffic towards Saint-Maurice.

In addition to the sidings (Losinger, Givo., CABV, AGIP), only Monthey station is open on the basic network for single wagonload traffic.
