I would like to make a few further points on the comments posted since my earlier post.
On clearer recollection, I exaggerated the number of day excursions; the number given was 48 not 58 (which I rounded to 60)
The majority of these came from the West Riding via Copy Pit and Lancashire but ones from further afield included Bristol (with an appearance of a Barrow Rd. Jubilee off its usual strict SW/NE workings). Blackpool was also popular in Scotland, particularly Glasgow, though I'm not sure of their were any day trips. Coming South, these turned left through the East Lancs platforms at Preston, right to join the Blackburn line West bound through Lostock Hall then right again to come back out on the Northern Union at Skew Bridge but facing North and so to Blackpool without reversal. Busked the interesting bit myself once!
Day excursions were for many the only option during the works holidays - I don't think we were poor, but a stay away was not affordable for my parents in the 1950s.
Road coaches weren't that good in the 1950s - early 60s. Likely to be one used on trips from school to the swimming baths in the week. Might have looked sleek and more modern than a steam train, but rattled (bits of trim sometimes fell off) with vibration, noise, leaked when it rained. Barbara Castle's introduction of the idea of a limit on coach drivers' hours was not well received in that industry, but the day excursion to the Illuminations would have been one driver working from one morning to the early hours of the next with little rest.
After a butterfly like early railway career it was decided, due to the apparent rarity of numerate railwaymen, that I was the ideal candidate to spend the rest of my time traffic-costing. I am untroubled by the general bad press that occupation seems to attract but, in my defence, I will make the point that in the complex network that was then B.R. there was a large number of possible ways to treat joint, shared, avoidable and marginal costs and these represented the overwhelming majority of cost causation in that environment . Using resources on their last legs is an example of the difficulty, although RfD did finally ran out of shoe-strings...
One of the factors that hasn't been mentioned is that British holiday resort organisations generally regarded their customers as fair game for exploitation. I remember the fish & chip restaurants where a board outside stated a price for that meal. The waitress under her breath committed you to also purchasing a slice of bread, a slab of butter and a pot of tea which, together, somehow resulted in a bill twice the advertised price. And 'residents' at B&Bs were unwelcome between the hours of 08.00 & 18.00, even in cases of torrential rain. The discovery that Spanish holiday resorts saw a connection between holidaymakers and their own own employment and income may also have been a factor in Blackpool losing trade. There were so many holidaymakers, that if you ripped off your customers the fact that they wouldn't return next year was not a worry. Pictures exist of the platforms at Central packed with passengers from the ramp to the exit and from coping edge to coping edge.
