As of 15 December (I shall be there on opening day) things are changing in the Leman area with the opening of the Leman Express (LE) regional network. I have not yet discovered if ticketing will change.
Anna, in an exception to the normal rule, STP is valid Martigny - Chamonix due in part to the cross-border joint venture (Mont Blanc Express). It is just possible something like that will happen in the LE area
