Northern has published a travel advice calendar for the seven days over Christmas (21-27 December).

The train operator expects to run a normal timetable on 21 and 22 December, but customers should expect disruption and are strongly advised to ‘check before you travel’ on 23, 24 and 27 December.

There are no Northern services on Christmas Day or Boxing Day (25 and 26 December).

Tricia Williams, chief operating officer at Northern, said: “Unfortunately, customers travelling immediately before and after the Christmas bank holidays should expect disruption.

“This is due to limited train crew availability in some areas. We strongly advise customers to ‘check before you travel’ on those days.”

In addition to the travel advice calendar, customers are reminded that rail timetables across the North of England changed on Sunday 10 December in line with the rest of the National Rail network.

Customers are encouraged to use the ‘Check My Timetable’ feature on the Northern website for more information about their local station.

Northern is the second largest train operator in the UK, with 2,500 services a day to more than 500 stations across the North of England.
