Rail passengers on the Harrogate to Leeds line will have to use a bus replacement service on Sunday.
Network Rail has announced work to install new overhead line equipment and signals will cause disruption after the last train on Saturday and continue throughout Sunday.
Normal service will resume on Monday, which is a bank holiday.
It means trains will terminate at Horsforth, and replacement buses will operate between there and Leeds station all day on Sunday.
Trains from Harrogate to York will run as normal.
The replacement buses will pick up and drop off passengers on New Station Street, in front of Leeds station.
Passengers are advised to plan ahead and check their journey with National Rail enquiries.
