NORTHERN is warning of disruption on its train services immediately before and after the Christmas bank holidays.

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

There are no Northern services on Christmas Day or Boxing Day.

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."

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.
