New London Underground boss Tim O'Toole has confirmed that he is considering closing entire Tube lines to carry out refurbishment.
O'Toole defended the proposal the transport committee of the London Assembly last week. He said: "If it was decided to go here, and there are obvious advantages, we would have to be dead certain we could deliver. I would not visit another Central Line closure on the public unless I was very convinced."

O'Toole said there were no immediate closure plans and lines would only be shut if alternative transport was put in place.

He said: "It would be essential that Transport for London put forward an integrated transport solution."

Building revealed in July that entire line closures were being considered by Tube consortiums Metronet and Tube Lines. The consortiums believe it could be cheaper and quicker to carry out work if lines were shut down.
