1948 -- Saturday night excursion from Burnley Bank Top (Central now) station to Blackpool I believe at 6 pm -- ticket included admission to Tower Ballroom -- return train leaving Blackpool Central station at 11 pm -- if you missed that train (some did) you had to wait for a train the next morning -- usually sleeping in a shelter on the Prom.
I missed it a couple of times, once walking back to Burnley through the night and early morning.
