(i have an interrail pass for first class anyways, just thinking if the reservation would make sense in first class or if a second class reservation is a better idea)
@mae I can vouch that while 1st class is compartment-only, the seats in 139A are absolutely worth it, the recline is not eurofima-levels(literal bed) but it's close to that
@mae as for the classification B - 2nd class obviously 9 - number of (in this case, virtual) compartments m - longer than 24.5m n - pretty much A/C o - equipped with push-pull enabling cable p - open saloon u - remote door control v - able to transport bikes z - equipped with a central bus power supply
