Tube Strike: Disruption easing on Tube network after strike ends
London Underground is returning to normal following the end of a second 24-hour Tube strike in three days.
The walkout by 10,000 RMT union members ended at 00:01 GMT on Friday, in a dispute over jobs and pensions. They had also been on strike on Tuesday.
All London Underground lines reopened by 08:00, although disruption was reported across the network.
Transport bosses urged people to work from home or use other modes of transport.
Most lines are running a normal service as of 12.00 on Friday. Minor delays are reported on the Circle and Hammersmith and City Line.
This week's industrial action saw all Tube lines at least part suspended and caused widespread chaos.
Andy Lord, Transport for London's (TfL) chief operating officer, said: "Services will be severely impacted until mid-morning on Friday because of a number of factors, including the placement of drivers and trains following a day without service.
"I apologise to customers for this and understand they will be frustrated by this strike action, but urge them not to take it out on those who are trying to help.
"We haven't proposed any changes to pensions or terms and conditions, and nobody has lost or will lose their jobs because of the proposals we have set out, so this action is completely unnecessary."

Rail, Maritime and Transport (RMT) union's general secretary Mick Lynch said: "The funding crisis at TfL which is at the heart of this dispute is not of our making and our members are not prepared to take a hammering to pay for it.
"This week we have seen workers fighting back across London against attacks on themselves and their colleagues from political machinations that are out of their control."
At the scene

A fourth day of interrupted Tube travel for Londoners - but at least passengers here at Kentish Town station can make their journey now that the Northern line has reopened.
The gates were open here anyway, as Thameslink trains serve the station, but it certainly feels as if the preference for working from home on Fridays has minimised the disruption this morning.
It's not unbridled joy for those heading down the escalator here in north-west London - the Northern line's Bank branch remains suspended between Moorgate and Kennington until mid-May due to engineering work - and the spectre of further strikes looms.
