Am I mistaken or are all the BR 110 locos modeled with their main circuit breakers (Hauptschalter) permanently open? From what I understand, the fork like thingy has to turn around by about 45 degrees and rest in the receptacle at the pressurized air switch for the MCB to be closed (see picture below). Maybe not a game breaker, but, well, the main circuit breaker at least. Would be great if this was animated (like the pantograph or the little ringer in so many US loco bells).
I checked that when I got BRO about two weeks ago and was disappointed that it’s not animated. Should look similar to this on a Swiss loco:
