By the way how about adding train activity to some "action free" screens (like elevator screens in Bonewerkz terminal)? For example there's a screen with several locomotives parked in a "roundhouse depot" in the background. Showing one of these locs starting up (deisel sound, clouds of smoke etc.) could increase the immersion in depot atmosphere. Also it would be nice to add some ambient sounds like coupler clangs, distant deisel roar, shunting whistles. It's a railroad station afterall.
