Tube workers are set to start another five days of strikes on Monday.
The industrial action is over the planned closure of ticket offices on the London Underground.
Around 750 posts will be lost in the changes to save about £50million a year.
Members of the Rail, Maritime and Transport (RMT) union will walk out from 9pm on Monday for two days and again from 9pm on May 5 for three days.

RMT acting general secretary Mick Cash called the planned changes to the network “toxic to the core”.
He said: “Staff are furious that while senior management pay and staffing levels are being allowed to roar ahead the jobs and pay of the core, station based staff who are the interface with the travelling public are being torn to ribbons.”
The first two days of action will take place ahead of a May Day event in memory of the late RMT leader Bob Crow,and politician and campaigner Tony Benn, who died within days of each other last month.
Mr Crow, who grew up in Hainault and lived in Woodford Green, died aged 52 in March and hundreds lined the streets for his funeral procession.
Phil Hufton, London Underground’s chief operating officer, insisted “significant changes” had been made in response to concerns raised in more than 40 meetings with the union.
He added: “There will be no compulsory redundancies and all requests for voluntary redundancy will be honoured....the RMT has not put forward any credible alternative proposals.”
The Central Line will run all night on Fridays and Saturdays from 2015 and more ticket machines will be installed if ticket offices close.
Some stations will see a boost in staff but the exact plans for Redbridge’s 12 Underground stations, including Hainault, Gants Hill, Wanstead and Woodford, have not yet been revealed.
