At first I thought it was an in game bug, but the more I continued along my route, the more I couldn't help but notice that it was a nice touch DTG added. When you play at night, the DB BR 767.2 seems to have a night light feature. For example when you're departing from the station, about a mile away after departure the interior lights seem to dim and when arriving a mile close to a station stop, the lights seem to brighten. I know its not a major detail but little things like that is what stand out to me. Good job DTG.
