Services on the East Coast Main Line are returning to normal after days of disruption caused by heavy rain.
Heavy rain caused problems for the network
There had been a replacement coach service between York and Doncaster after the River Don rose above safety levels at a railway bridge.
GNER has announced that rail services will resume between Scotland and London, and the company aimed to operate a full timetable.
Passengers are being asked to stagger their journeys to avoid overcrowding.
John Gelson, from GNER, said: "We've told passengers who couldn't travel on Monday or Tuesday that they can travel today or tomorrow on tickets valid for those two previous days.
"There is plenty of opportunity to spread out their journey, and they would probably be wise to do so until the service gets fully up and running again."
