This morning, going through the timetabled services for the 146.2. I decided to drive from Hagen Hbf - Wuppertal Hbf via the mainline. Hagen Hbf was busy with passenger trains and a passing freight into the yard, it was good to see it so busy! I got to Wuppertal Hbf, racing an S-Bahn on the approach into Wuppertal Hbf. I decided to drive back to Hagen Hbf on the S-Bahn, so I carried on in "Free Roam". I waited for the next S8 before taking over. It soon became apparent though that I was the only moving train. Nothing passed me going the other way and nothing was at Hagen Hbf waiting to go the other way. This is a bug surely? I was under the assumption that the timetabled services were meant to keep running.
