I recall sometime around late 1989, having arrived at Piccadilly on a late evening class 47 hauled pennine, catching the last Crewe service with a 304 to make the overnight to Holyhead for more 47 action. Anyway a few of us were relaxing on the cart and as we pulled out, rapidly gaining speed, a drunken young couple opened the door and launched themselves onto the train and landed on my mate who by then was dossed out.....he wasn't amused!
