British Rail had it's own licencing laws back then, just like there are still additional Byelaws which only apply on railway property. Criminal trespass for example. The tourist steamers on Lake Windermere were also run by British Rail. So when you got booted out of the pubs at 3:10pm you would wander down to the pier, get the next steamer to Ambleside and contnue getting plastered. Back on the return steamer to Bowness for 5:30pm and back in the pub. Applied all day on Sundays too.
