I'm planning a Swiss rail adventure, but I'm hitting something odd with Rail Europe. If I search for journeys on the Tirano to Chur route (normal trains, not the tourist train) then I get some results (but not all) if I apply a 2nd class Interrail pass, but if I apply a 1st class one I get a message that no journeys can be found.
Has anyone come across this before? Is the 1st class pass valid on these trains, or only the 2nd class one? (That doesn't sound likely, but why else would I only get results with a 2nd class pass?)
Oh, and also, on the tourist train, is the fee only payable if you use the panoramic carriages, or does it also apply even if you sit in the EMU hauling them?
