I was thinking I would like to go from Vienna-Melk & continue on to Salzburg by train. Seems that the REX train is the most direct way to get from Vienna to Melk. Then can we just continue on to Salzburg?
I find the train schedules to be very frustrating. In the US for Amtrak or whatever you can usually type in 2 major cities & it will give you a big grid with the timetable of all the stops in between. I can't seem to get that from OBB or rail Europe.
Any Advice
