USERS of Northern trains have been warned to expect delays and cancellations on Sunday (July 15).

Northern said there will be 'possible disruption' due to some train crew having made themselves unavailable to work.

Customers have been asked to plan carefully ahead as Northern will be running an amended timetable across much of the North West.

Many services in Cumbria, Lancashire and Greater Manchester are likely to be cancelled. Some services in Yorkshire will also be affected.

Liam Sumpter, regional director for Northern, apologised for any potential disruption.

He said: “Unfortunately many of our staff have made themselves unavailable for work on Sunday.

"Our operational teams are currently working on a plan to make the best use of those staff who are available and to run as many services as possible.

"It is, however, inevitable that many services will be cancelled.”

Northern customers have advised to check the Northern website and National Rail Enquiries for the most up-to-date information.

Mr Sumpter added: “We are very sorry for any disruption to our customers’ journeys and can assure those looking to use Northern services that we are doing everything we can to keep people on the move.

“We are still working on our plans for Sunday and will release further details of which services and routes are affected as soon as possible.”
