Travellers on the East Coast Mainline whose journeys have been disrupted by gales now face travel chaos over Easter as workers plan strike action.
Passengers should check travel times with National Rail Enquiries
The track between York and Doncaster has been blocked by fallen power lines brought down in this week's high winds.
Train operators were running reduced services between Scotland and York, and between Leeds and London.
Services will be hit again as workers in York stage a five-day strike from next Wednesday in a row over job cuts.
The dispute involves electrical workers at a Network Rail control room in York which supplies power to the whole East Coast Mainline.
The Rail and Maritime Union (RMT) members will not work any shifts between Wednesday evening and Easter Monday morning.
However, Network Rail said some services would continue despite the action.
The union said the action was in protest at a scheme to cut the number of jobs at the North Yorkshire site from 18 to 12 and comes after a vote in favour of industrial action.
General Secretary Bob Crow said the action was because of "drastic cuts and safety issues".
Network Rail said the walk out was "premature" and East coast mainline services would not be badly hit.
The damage to power lines on the route happened on Wednesday afternoon, but persistently high winds made it too dangerous for engineers to begin repairs.
Work was under way on Thursday and was expected to be completed by about 1600 GMT.
