Train services on the East Coast mainline between Edinburgh and London are threatened as a result.

The Rail Maritime and Transport union said a majority of members at York backed industrial action in protest at plans to reduce staff by a third.

Network Rail said consultation was underway and final arrangements were yet to be agreed.

Network Rail has until Thursday to resolve the dispute or industrial action will result, the union said.

The RMT members will not work any shifts between Wednesday evening and Easter Monday morning (links below.)

However, Network Rail said some services would continue despite the action.

Maintenence and contract work on overhead power lines along the East Coast and branch lines was cancelled last night after key engineering staff in four Network Rail depots refused to issue work licences on safety grounds (link below.)

Workers at Morpeth, Leeds, Doncaster and Hitchen depots invoked 'Worksafe' procedures and sought alternative duties after learning that managers doing the work of highly skilled staff on strike from the York electrical control room had had as little as six days' training.

RMT members at the York ECR started a five-day strike last night over Network Rail's plans to slash the number of operators there by a third.

Work scheduled to take place at Heaton depot today was also cancelled after the necessary licences were not issued.

The union has today warned that any attempt to discipline the workers concerned would result in a ballot for strike action among all overhead-line staff.
