A spokesperson for Rail Delivery Group said: “Train operators have been affected by ongoing global IT issues which may result in some short notice service changes and cancellations, also impacting real-time information screens and services at stations. We are sorry for any customers experiencing disruption to their journeys today; staff are working hard to resolve the issues as soon as possible.

“Most trains are still running across the country and rail staff will be able to provide the latest information to customers in person. You can also visit the National Rail Enquiries website for the latest updates.”
