Track upgrades are set to take place at Leeds station over the Christmas period to boost the reliability of services.
The track layout will be remodelled between platforms 4 and 6 by engineers to reduce the impact of future unplanned disruption.
Major work is set to take place on Christmas Day and Boxing Day when no train services are timetabled.
The improvements will allow more trains to run and will reduce the impact of future unplanned disruption across the North.
New overhead wires are also set to be installed whilst work will be done to ensure the equipment and platforms align with the new track.
New signalling equipment will also be installed and tested to ensure trains can continue to run safely and reliably.
Changes to the timetable will impact passengers until Monday 3rd January as work continues on the complex project.
A limited number of services will run on Sunday 2nd January when buses will replace trains and journeys will take longer.
Between 27th December and 1st January a reduced train service will run in and out of Leeds station with some bus replacement services in place.
Matt Rice, North and East Route Director for Network Rail commented on the importance for passengers to check journey times before travelling over the festive period.
Mr Rice said: “Last Christmas was a non-event for many.
“Because of that I know lots of people will be eagerly looking forward to getting out and meeting friends and family this year.
“While most of the railway will be open most of the time, it’s really important to check your journey times before setting off, particularly on 2 January.
“The track upgrades at Leeds mean some routes will be by coach, or may take longer by train depending which days you’re travelling.”
Rail Minister Chris Heaton-Harris spoke on the importance of the work taking place at Leeds station.
Mr Heaton-Harris said: “Leeds is a major hub that draws in passengers for work, shopping and its vibrant night life.
“Every journey through this station should be punctual and reliable.
“The works taking place over the Christmas period are important in ensuring excellent services run in and out of Leeds.
“[The works build] on the work already taking place to boost transport across the North through the Integrated Rail Plan.”
