I tried creating a scenario with the DB BR 101 going from Asschaffenburb platform 5 to Gemunden. Firstly when setting up an AI service, I selected it to be a 146.2 but instead a 143 spawned in (alsoalso 143 didn't appear in the loco list when creating the service.) Secondly I think the red light bug is back on MSB as I've been able to run a scenario with the ICE3 no red light issues but now the light won't go green even when there's nothing in my way and nothing else has a green.
The solution to the red light issue used to be to choose off the rails, even if you're using trains native to the route. Does that work?
Thanks! Put it in off the rails and finally a green. Hopefully this may resolve the available loco list problem as well.
