Travellers are being asked to check their journey following a number of Covid train cancellations.
Northern Rail has asked people to check train availability due to timetables being reduced an amended on certain routes due to the availability of train crew as a result of Covid-19.
On Twitter, Northern Rail said: "An amended and reduced timetable is in operation on some routes due to the impact of COVID and the availability of train crew.
"Journey planners have been updated. Make sure you check before you travel."
Many operators across the country are currently operating on reduced timetables in a bid to improve reliability after weeks of short-notice cancellations due to staff shortages caused by the coronavirus pandemic.
Demand for rail travel is at around 50 per cent of pre-pandemic levels.
This is partly due to the guidance for people to work from home.
