Tube services are returning to normal after a 48-hour strike over planned job cuts and ticket office closures caused chaos for London commuters.
Talks will be held later between London Underground bosses and the RMT and TSSA unions, in a bid to avert a second strike.
Transport for London has said the proposals, which would lead to 960 job losses, would save £50m a year.
Millions were affected by the strike, which ended at 21:00 GMT on Thursday.
As it ended, London Underground (LU) said up to 190 of 270 stations were open, but a full service could not resume immediately because of shift patterns.

Further industrial action is planned for between 09:30 and 11:30 and 18:30 to 20:30, when the unions are asking members to leave ticket barriers open.
They are also urging members not to issue penalty fares.
LU’s chief operating officer Phil Hufton said the company was “not obliged to pay employees in full if they refuse to carry out their full range of contractual duties”.
A second two-day walk out is planned to begin next Tuesday evening, if talks between both sides are unsuccessful.
‘Baloney from Boris’
Ahead of the talks, which will be chaired by the conciliation service Acas, the Mayor of London Boris Johnson told BBC London 94.9, there was “wiggle room”.
He said unions had shown a “failure to engage” in talks, adding: “Rather than hurting hard-working Londoners and hard-pressed small businesses they should have been talking to TfL this week.”
RMT leader Bob Crow said it was the first he had heard of “wiggle room”, adding: “My negotiators have been told for the last five weeks there is none.”
He added: “Our negotiators are geared up and ready to enter the exploratory talks.”
TSSA leader Manuel Cortes said: “We want no more stunts or PR baloney from Boris. We want serious and detailed talks on our genuine fears for the safety and security of passengers and staff under these far-reaching plans.”

Val Shawcross, Labour’s transport spokeswoman on the London Assembly, has urged the mayor to launch a full public consultation on the plans, which he says will not lead to compulsory redundancies.
She said: “There are some interesting ideas in TfL’s plans and modernisation is needed, but Londoners should be given the chance to have their say and improve them.
“No-one has a monopoly on good ideas and Boris should be willing to listen to what the public have to say. The unions have raised legitimate concerns over passenger safety and how more vulnerable Tube users will be affected by the changes.”
The government has said it is considering plans to declare London Underground an essential service, like the police, in order to curb the threat of future strikes.
