Rail firm Transpennine Express has suspended half its services from Liverpool Lime Street because of delays in the roll out of a new fleet of trains.
Train passengers face weeks of disruption because of the cancellations on the Liverpool to Edinburgh route.
It means fewer Transpennine Express services linking Liverpool, Newton-le-Willows and Manchester Victoria.
The company also blamed a maintenance backlog and infrastructure issues for causing a delay in staff training.
It said it hopes to return to the full timetable on 24 January.
