Currently playing the new Cargo line pack and playing 6V64 scenario on Preston Carlisle and my window wiper has stopped working completely won't move when I put it into run and worse bit of all is that it snows during it and can not see anything Loco is the 47 in BR LL on WCMLOS
Without going ahead and checking, is the manual window wipe functional? - it's the lever on the back of the motor.
If the manual wiper still works then we may be seeing a return of the bug from TSW3 where the wiper would randomly stop running, requiring regular manual inputs to clear the screen. I remember it happened to me once - that was a fun 395 run!
I suppose that it's good news that the old bug hasn't resurfaced. Still, we do need to find out why the wiper failed and I've no ideas...
