I can't the locomotive startet vhen complet to the freigtcars? I've foliowed the tutorial but it dos'nt work?
Its a known bug, its been fixed but we are waiting for the route to be signed off from testing and eventually it to be released along with the 16other routes worth fixes and updates that are also in testing. Hentis
Actually, that bug fix was released some months ago -for TSW2. However the OP is playing TSW2020. Since the red-light bug was created by the conversion, his issue must be something else.
I think it wasn’t the port. As far as I remember, the signalling was touched for the 363 DLC and that introduced the infamous bug.
