I am evaluating the manner of making a day trip to The Semmering line, exclusively by train and bus.
E.g. Starting with Railjet Wien to Wr Neustadt and regional train to Goggnitz or Payerbach and from there alternate local buses and regional trains making stops in the most interesting places , and returning by railjet in the afternoon /evening from Semmering or Mürzzugschlag to Wien.
Is this approach feasible? Are there ticketing/passes/formulas for regional trains and buses that can be used to hop on and hop off in the region ?
