RAIL operator Northern says some service changes will be introduced next month when new national timetables are launched.
But the company, which runs trains on the Airedale line, says the "vast majority" of its services will be unaffected.
Amendments are being made to some journeys from Leeds to Skipton and stations in Cumbria, with extra capacity and additional stops.
The new timetable comes into force on Sunday, June 2.
Matt Rice, Northern's chief operating officer, says: "We’re all set for the new timetable. The vast majority of our services are unaffected, but there are a small number that have been re-timed."

Northern is the second largest train operator in the UK, running nearly 2,500 services a day.
