Did Blackpool North initially take all those 54 trains a day or was there some rationalisation?
Blackpool North (the town's main station today) was the one slated to close but the Corporation cast their greedy eye on the railway estate of Central that lay just behind the promenade and came to a cheap deal with
BR▸ to swap the two stations around. Those 54 services terminated short at Blackpool South for nigh on 7 years which was clearly unsustainable with only two working platforms. I think the last London Euston express moved to the North station in 1972. Today, the line to Blackpool South is just a withered single track siding with a train service to match.
