Safety risks have been denied by Transport for London during this week’s planned tube strike after London Underground says it will operate a full service across the whole of the network, including Jubilee, Piccadilly and Northern lines maintained by Tube Lines, throughout the duration of the strike. All stations will also remain open.

Tube Lines workers are set to go on strike from 7pm on Wednesday after talks between the company and the RMT union broke down.

The union claims the public will be at risk if under-qualified staff members are put in charge of trains during the industrial action.

TfL has assured the public there will be “no compromise” on safety standards and emergency teams were in place in case there is a problem on the network.

A TfL spokesperson said: “Safety is London Underground’s top priority and we would never run trains if it was not safe to do so.

“Should the action go ahead, we do not anticipate any significant impact to Tube services and London Underground intends to operate a full service on all Lines.”

But RMT general secretary Bob Crow said it was clear the strike would have a “major impact”.

He added: “There’s a real danger that tube officials will take serious risks with safety to try and run trains.

“We welcome the intervention of our colleagues from the Fire Brigades Union to try and stop that from happening. No one should underestimate the safety-critical role of the tube’s maintenance and emergency response crews.”

Contingency measures have been put in place in case the strike does happen, with extra Thames Clipper services dedicated to Canary Wharf and extra bike parking facilities in Cabot Square.
