My wife and I are visiting Germany and Austria (Salzburg) this months for approximately 2 weeks and we have subscribed to the Deutschlandticket. I understand that this ticket does not cover any high-speed trains (i.e. the IC types), but I want to make sure that we understand what is available to us. We purchased the tickets via the FahrPlaner App for Android.
For example, we are arriving in Munich via an IC train I had already purchased tickets for, but we are trying to connect to Salzburg for the final leg. I think that we can use the DT for travel on the hourly BRB RE5 train to Salzburg (I am also assuming I can use the DT to return to Munich on the outbound BRB RE5). Am I correct in that assumption? Also, do I need to make some sort of reservation, or can we just "show up" before the train leaves and just present the DT ticket on our phones?
If my assumption is incorrect, then what train line should I be looking to in getting to Salzburg that is covered under the DT?
Thank you all for any advice or confirmation!
