Im looking at potentially visiting the cite du train in Mulhouse as part of an Interail trip across Europe, as such I'h have a global Interail pass. Looking at the map I understand I need to get the tram train from the main station to the Musees stop. I was trying to work out if the Interail pass would be valid for these services, The Interail.eu site and their app indicates that the passes are valid on SNCF services, but Im still unsure weather or not the tram train is an SNCF service. The Wikipedia article on the tram train indicates that 75% of the drivers are from SNCF. So does anyone know if I can use an Interail pass on the Mulhouse tram train or will I need to buy a separate ticket?
