I am now taking the Cityjet to Payerbach-Reichenau at least… the Railjet still stands here, let’s see if this leaves before it does. Probably arranging the SEV from Gloggnitz takes time or something. (Edit: no, the Railjet left just before we did. Which makes sense, this train stops many times before Gloggnitz.)
This was supposed to be just a day trip until I can check in to my Airbnb in Vienna but turned into a minor ad-hoc travelling adventure. Lovely! (Not sarcasm.)
