DFG Hello. If SBB cancels (not the commuter) the Saver Day Pass for any reason (construction work, for example), will SBB refund. The scenario is the Saver Day Pass was bought a month or 2 ahead of travel. Thanks, DFG
Danhiel DFG Hello The SBB will never cancel a Saver Day Pass which is valid everywhere in Switzerland. In case of construction works on a specific line, you have alternatives: the trains will be diverted to another route or you can take replacement buses.
