Bit of a late response but years ago there was a good long distance diary in T&D about an H&S foodstuffs driver who used the train you mention, I remember him saying that he’d parked the truck on the train with plenty of spare time and decided to go for a beer at a bar nearby but he couldn’t relax because he kept having visions that the train was gonna pull out the station…without him on it 
So he thought better of it, supped up and waited on the train.
