On the Rail Europe website, I'm able to access round trip trains from Vienna to Melk but only if I buy the point to point ticket not if I indicate that I'm using a rail pass. Does anyone have any experience with this trip and the use of a rail pass? All other trips I've searched show availability. Thanks.
Sorry, I did find this explanation at the site:
Q. When I select the box that says I have a pass I am not receiving any schedules, but when I do not select the box that says I have a pass I receive schedules. Why can't I book a reservation with a Pass?
A. The train you are requesting does not offer reservations. Please note the train time for your travel information. To board this train you will need your pass and can take any available seat.
