Major works start on West Coast Main Line
An £18m improvement scheme to increase the speed of trains is starting on the West Coast Main Line.
It will mean no services between Preston and Warrington Bank Quay until 21 July.
Carrying out the work on continuous days will mean less overall disruption than doing it over a number of weekends and bank holidays, Network Rail said.
Local trains will be replaced by buses and there will be diversions for longer journeys.
When completed, the work will allow trains to run at up to 75 mph over the four upgraded junctions - Golborne Junction, Bamfurlong, Wigan Springs Branch and Balshaw Lane Junction.
