Always the app of the country you are travelling in. Here: ÖBB.

But there shouldn't be different times. Maybe ÖBB does show trips that do include a bus. That's not shown on DB app.

To check timetables in Austria, either fahrplan.oebb.at or the ÖBB Scotty app.

Thank you. I will use the OBB app. The journey on OBB is dep12.12- arr 13.41 (1 hour 29) whereas DB is 12.11- arr 14.24 ( 2 hour 13).

So OBB seems more realistic ( maybe bus journey as someone said is included on DB app) 

Many thanks  

Could you post a screenshot ? 1h29 seems impossible by train. Maybe there’s a bus section showing on OBB but it wouldn’t be included in Interrail.

In any case you’re too early for July timetables and I would wait check again closer to travel.

Here it is, thank you for taking a look! 

Do you wish to go to Bad Goisern or Bad Gastein? I think that will answer your question. ;)

Bad Goisern! Thank you, I  see my big mistake now, similar names, I’ve got myself muddled with all of this interail planning
