I have noticed, that German level crossings in TSW2 doesn't look quite correct, like British or or American crossings. The lights on German crossings should be bigger, and not flash. The red light should be solid. Real life: TSW2: (Screenshot taken from Hamburg-Lübeck preview video)
I immediately noticed that too in the trailer. It really surprised me, as they had enough feedback on the level crossings and their lights on older German routes like MSB and RSN.
