This is a small and quick one, but I suggest that the ICE service names on the new German route Schnellfahrstrecke Köln - Aachen show the starting point of the service aswell as the end. So all trains currently labeled as "ICE xxx: Bruxelles Midi" would then be called "ICE xxx: Frankfurt (Main) HBF - Bruxelles Midi" and vice versa. It's just a small thing but I think it helps the feel that you're driving an actual service.
