Local TER trains are being disrupted with action by conductors who are unhappy with a new anti-fare dodging regime that SNCF wants to initiate on trains from Sunday. Most services will run, but in some cases with replacement bus services.
Services to Toulouse from Figeac (ie through Villefranche, Lexos and Gaillac) will terminate at Tessonieres from where a bus will take over. There may be fewer trains on the Toulouse/Figeac journey.
