Strike action could cause further disruption over Easter

Passengers were being advised not to travel on Wednesday and Thursday as speed limits were imposed on the track and power cables were brought down.

All damage caused has now been repaired, according to Network Rail.

Mainline operator National Express said tickets bought for travel on Wednesday or Thursday would be valid on Friday.

Production director Richard McClean said: "I would like to thank customers for their understanding in the last couple of days and the co-operation of other train operating companies in enabling passengers to complete their journeys via alternative routes.

Electrical workers

"I would also like to thank Network Rail's teams for their hard work in carrying out the necessary repairs in very difficult circumstances."

But services could be hit again over Easter as workers in York stage a five-day strike in a row over job cuts.

The dispute involves electrical workers at a Network Rail control room 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.

Network Rail called the walk out "premature" and said some services would continue despite the action.
