Railway commuters are warned that there could be disruption over the Bank Holiday weekend.

Most trains will not call at Bushey or Harrow & Wealdstone at a point over the weekend between Saturday (May 29) and Monday (May 31) as the Network Rail upgrade tracks and signals across the railway.

During the upgrade, there will be fewer trains between London Euston, Birmingham and Liverpool.

Trains to London Euston from Northampton, Milton Keynes and Tring will run to amended timetable on Saturday, with most trains will not call at Bushey or Harrow & Wealdstone.

Other changes include:

• Passengers travelling between London Euston and Birmingham on all three days will need to change at Northampton on many services

• Trains between Crewe and London Euston will run to an amended timetable on all three days

• A reduced number of trains will run between Northampton, Milton Keynes and London Euston on Sunday 30 May and Monday 31 May

• No direct trains will run between Birmingham and Liverpool on Sunday 30 May and the morning of Monday 31 May

Lawrence Bowman, customer experience director for London Northwestern Railway, said: “These important upgrade works will ensure smoother and more reliable journeys for our customers over years to come.

“While the work is carried out I am urging our customers who are planning to travel on the West Coast Main Line over the bank holiday weekend to check their journeys in advance and plan carefully.”

Tim Shoveller, managing director of Network Rail’s North West and Central region, said: “These essential improvements will build on the great progress already made this year to improve the railway as passengers return in greater numbers.

“I urge people to check their travel in advance so they know exactly what to expect from their journey.”
