The Hanover-Bielefeld route would be nice. Train sim world would be happy to report sounds for vehicles
Now, let's imagine this folks: In comparison to all the sophisticated route proposals raised in the suggestion forum, with people giving literally their complete power and soul away to provide every single aspect to make the route as attractive as possible for DTG, and someone in DTG goes into here and simply says "Dortmund - Hannover? Great idea! Let's do this." Makes me laughing and crying at the same time.
