A spokesman for Northern said: “The impact of ongoing engineering work means we have to adjust our Sunday timetable each and every week.
"This has an impact on matching drivers’ availability within their working agreements. Routes have been chosen carefully to minimise the impact on customers.
"On each of the affected routes, our customers will have a range of alternative options available to them, including: other Northern services, trains run by other operators or rail replacement transport.
"We are sorry for the inconvenience this will cause our customers. Please check immediately before you travel."
