I will be traveling this summer from Copenhagen to Hamburg (Deutsche Bahn or DB), Hamburg to Strasbourg (DB), Strasbourg to Toulouse (DB + SNCF), and finally Toulouse to Barcelona (SNCF + R3). I have the Eurail Global pass. My question is, in DB and SNCF trains is seat reservation mandatory? In the Eurail application, it shows “reservation required” on most trains, which is strange, because when reading through the https://www.seat61.com/interrail-and-eurail-reservations.htm#eurail-interrail-reservations-service it seemed that except for some high-speed trains like TGV, etc seat reservation is not mandatory although is advised. One can just hop on, choose an empty seat and show the pass. I would hate to land in problems while traveling and pay hefty fines. It would be great if some of you could help me with your experience. Thanks a bunch!
