Train passengers are being told not to travel on Friday as union members prepare to go on strike.
Avanti West Coast said it will be unable to run any trains on Friday as the train drivers union, ASLEF, goes on strike.
Customers are being told not to attempt travel and instead claim a refund, seek alternative transport, or rearrange journeys for another date.
Options to travel by rail will be extremely limited on the West Coast Main Line between London, Scotland, and North Wales. Many destinations will have no rail connectivity on May 12, and rail replacement services will not be in place either.
ASLEF members at 16 train companies have been in dispute for almost a year over pay. The union said most drivers have not had a pay increase since 2019.
On Saturday May 13, Avanti customers are strongly advised to check before they travel as the intercity operator will be running a greatly reduced timetable. This is in response to strike action by the RMT co-ordinated across train operators.
The reduced timetable on May 13 will mean North Wales, Shrewsbury, and Blackpool have no Avanti West Coast services. Due to major upgrade work by Network Rail near Carstairs, there will be no direct trains to Scotland.
Journeys to Glasgow and Edinburgh will involve a change at Carlisle, where connections into rail replacement services, as well as a limited rail service operated by ScotRail, will be available.
With fewer services running and a reduced operation, trains could be busy and customers are strongly advised to plan ahead, expect disruption and check before they travel and be aware of their last train home.
Customers with tickets for May 12 and May bought before April 27 can claim a full fee-free refund from their point of purchase. Alternatively, tickets dated May 12 and 13 can be used from May 11 up to and including May 16.
Other train operators have yet to release their advice.
