Salzburg - Rosenheim Info Please

If I asked this already sorry on this route does the OBB 4024 does this loco do the whole of the route. I'm just keen on the BR 111 thanks

 

Br 111 does services to Salzburg, the Dostos do the return trip, ÖBB 4024 does S-bahn between Freilassing - Salzburg

 

What layers into this do you know thanks.

 

-Br 101 (including expert)
-ÖBB 1116
-Br 628
-Br 103
-ICE 3 (AI)
- A bunch of freight locos

 

Thanks for your info and help appreciated.

 

Nice route i like it 4024 seem a bit pointless to me but thats just opinion.
