Northern has said that services should return to "normal" on Wednesday, January 3.
Tricia Williams, chief operating officer at Northern, said: "Unfortunately, customers travelling over the New Year period should expect disruption.
“This is due to limited train crew availability in some areas and planned engineering works.
"We strongly advise customers to ‘check before you travel’ on those days."
In addition, Northern has also reminded customers that rail timetables across the North of England changed on Sunday, December 10 alongside the rest of the National Rail network.
Travellers are urged to use the ‘Check My Timetable’ feature on the the train operator's website for the most recent updates to scheduling at their nearest station.
Northern, the second largest train operator in the UK, handles approximately 2,500 daily services to more than 500 stations, and employs over 7,000 people across its network.
A total of over 100 million passenger journeys are made on the network each year.
