It isn't caused by having or not having the 363; the problem was caused by the route's timetable being adjusted to accommodate the 363, which is coded into RSN now independent of owning the DLC.
Released a temp fix for now on this thread. https://forums.dovetailgames.com/threads/ruhr-sieg-nord-freight-exchange.38414/#post-335573
I installed the game on my PS4 (playing it regularly on PS5) and only added the route DLC. The Scenario is broken from start, there simply is no route, so the signal won't ever change nor the Signal Operator would respond.
right, but you don't have to skip scenario if you like to play consecutive suggested (training) missions there is more to improve on the whole DLC
Didn't notice any brake dragging myself. Did finally complete the scenario, but only got silver even though it was a near perfect run (minor overspeeding just once). I guess it will take another year before it is completely fixed :P
You won't even have got gold with a perfect run (5110 AP), because 5350 AP are needed for that. The possibility to just drive back and forth is also limited. All I could think of is the siding when the first run is finished. You could do it before the uncoupling.
