Which country for Mittenwaldbahn? Are you considering the German or Austrian route? The route is mostly Austrian in terms of length, and what's more, we know that one of the most important trains in this add-on will be an OBB train and not DB. (OBB 1020). So why consider it German like some people ?
Well, in terms of length the ratio is about 3:2, so it's not an "almost all" route like Vorarlberg or Rosenheim; and although the new loco will be an OBB Krokodil the traffic is about 50/50 DB and OBB. I don't know what was running in 1989; today it's Talent 1s (OBB) and Talent 2s (DB), with one ICE train pair per day (2 on weekends). At a guess I would think the Austrians were running Toasters and the Germans 139s, neither of which are in the game. But the OBB conceivably was using Krokodils for all services, since the grade gets up to a brutal 3.8% and receives lots of snow.
