A 24-hour Tube strike will hit London commuters this evening and tomorrow after negotiations failed to reach an agreement.
Rail, Maritime and Transport union (RMT), Transport Salaried Staffs Association (TSSA), and Unite members will walk out at 18:30. Aslef workers will begin their strike action at 21:30.
Transport for London (TfL) said the majority of trains will stop running by 17:00, and is recommending commuters complete their journeys before then.
Mick Cash, RMT general secretary, said: "Despite strenuous efforts by union negotiators to press London Underground to address the issues of fairness, safety, work-life balance and equality at the heart of this dispute, they have come up with nothing in the talks this afternoon."
TfL said extra bus and river services will run on Thursday in an attempt to ease disruption.
On Monday, unions rejected London Underground's "final" offer of a 2% pay rise and £2,000 for 'Night Tube' train drivers.
