London Underground services were returning to normal today after a 48-hour strike over ticket office closures which caused travel disruption across the capital.

Members of the Rail, Maritime and Transport union ended a 48-hour walkout at 9pm last night and are set to stage a three-day strike from 9pm next Monday unless the deadlocked row is resolved.

Talks will be held at the conciliation service Acas tomorrow in a bid to resolve the dispute.

LU said it ran 52% of Tube services yesterday despite the "pointless" strike, and carried 56% of its usual passenger numbers, which it said was a record for a strike day.

Around 80% of stations were open and services ran on 10 of the 11 lines, said the company.

The RMT continued to dispute the figures, accusing LU of "misleading" the public over the level of services and of leaving platforms and stations "dangerously overcrowded".

The union said the strike remained "rock solid".

Mick Cash, RMT acting general secretary said: "We have set out a viable plan that could move the dispute forwards.

"If LU halt the cuts juggernaut we could suspend our action allowing a full consultation of all stake holders on the future of the Tube including staff and the travelling public. "We believe that is a sensible and responsible way forward."
