We will be flying in to VIE and I have the following questions re: train travel.

Our plan is to fly into VIE and take the train from VIE to Salzburg...is that doable from the airport and, if so, is there only one line that serves the route?

Our return from Salzburg would be to Vienna a few days later or, another option would be, return to VIE.

Is there only one line that serves the itinerary or are there several choices?

We would have several pieces of large luggage...will that be a problem on the train/s?

As you can see, I am not experienced with train travel in Europe and any information/advice would be greatly appreciated!

Thank you to anyone who responds and to all who view this message...I wish you a Healthy, Happy and Prosperous New Year!
