Passengers on trains to and from Liverpool have been advised to only travel if absolutely necessary during next week's strikes.
Network Rail said about half of all rail lines will be closed when thousands of workers walk out across Britain on June 21, 23, and 25. Services that do run will start and finish much earlier than usual, from 7.30am to 6.30pm, with train operators expecting to run very limited timetables.
The operators have told passengers to not travel on the strike days unless absolutely necessary. Customers should try to find alternative transport to and from the city if their journey is essential.
