So I've just had my first go on the new Spessart Bahn DLC, did the tutorials okay but thought I'd have a go with a freight train in the service mode (rather than immediately try a scenario). Headed East I got about 60% along the route and came to a red signal so stopped 10 or so yards before it. After a moment a passenger train came the other way but once it passed, the light stayed red. I waited a few more minutes but it still stayed on red. I asked for permission to pass but was denied. 15-20 minutes later I'm still sat there with the signal on red. A Steam user has reported that "the station Laufach is the block... after some time you have several trains in both directions standing at red signals around Lauchach. It´s a total jam ... no chance for green signal."
