I checked the official train times before posting.
There will be no trains before 8.00am, but the schedule after 9.00 is confirmed as a normal schedule (Blackpool - York). It's quite usual for the Blackpool trains to run without interruption on a Bank Holiday Monday.
I'd always recommend that anyone planning to use the Calder Vale Line should check that there are no alterations to scheduled services, as Oz says, but provisionally everything is OK.
Jase, yes one or two nutters around. However, let's hope that since our last visit to the Shay the police have got the message that Accy fans are totally well-behaved (unlike a certain West Yorkshire officer in search of some overtime).
Best advice I can give is Keep Your Cool, Rise Above It, Don't Be Provoked . . . .oh, and Carry A Camera !
Friendliness and good humour will always triumph
