I understand that you can drive the 146 in Köln-Aachen, but I currently cannot find the destinations for the NRW Express (RE1) in the route, which goes from Aachen to Hamm. Is it okay if DTG will add them in the future?
+1 for this suggestion. All of the AI 146.2's boards read 'Nicht Einsteigen' which I'm assuming means 'Not in Service'.
