Millions of commuters in London are facing delay and disruption due to a 48 hour strike on the Tube.
Three of the 11 Tube lines were shut on Wednesday and others operated a reduced service, while many stations were closed until Thursday evening.
The disruption was compounded by delays on overland train services caused by rain and high winds.
The strike and another planned next week by members the RMT and TSSA unions, is in protest at the closure of all 278 London Underground ticket offices, with the loss of more than 950 jobs.
Union leaders warn many stations will become "ghost stations".
London Mayor Boris Johnson said there would be no compulsory redundancies and the changes would save millions of pounds to reinvest in the Tube system.
British Prime Minister David Cameron said the strike would “inflict misery” on Londoners.
