People planning a bank holiday get away are being urged to check before they travel because the West Coast main line will be closed.
The railway will be closed between Saturday and Monday, reopening on Tuesday.
The bank holiday weekend closure will affect passengers from across parts of the North West, Scotland and the West Midlands who plan to travel to London along the West Coast main line and means alternative routes will have to be used to travel in and out of London.
Jim Syddall, acting route managing director for Network Rail, said: “A huge amount of work has been completed over the last two weekends but there is still a significant amount left to do over the August bank holiday weekend.
“There is never a good time to close the railway and we apologise for the inconvenience caused but this work is essential.”
