If you have issues like this, just swap,out the offending unit (for one you know that works) using loco swap. Life’s too short to waste time finding obscure locos for a scenario. If it’s not the player train, F2 then cancel, gets things moving.
Just tried to play this – when boarding at Barnham the 377 doesn’t have a unit number and all the lights are on cannot key on properly
