(PC version) I can't back far enough into that siding at Chur north (I think that's right) before I run into the bumpers or derail. Literally can't reach the objective marker. I think the intention is to drop off the empty wagons there.
Have you tried just that? Because the objective will clear then. Sometimes the loco doesen't need to be ON the marker
Are you sure it’s not the wagon or wagons that need to be on the marker and not your loco? It may still show a large distance to the marker but the wagon itself will be over the marker. The distance is just how far you are from it in the loco.
I had to gently rest ot against the buffer stops in order for it to work. It's definitely too close to the end.
