RMT and TSSA Tube staff, including station staff and some drivers will begin their 24-hour strike at 18:29 on Sunday 3 October, and maintenance and engineering staff will start at 19:00. Tube services will not return to normal until the start of services on Tuesday morning, 5 October.
Disruption is likely to most journeys, but London Underground will run as many trains and keep as many stations open as possible - check www.tfl.gov.uk for the latest situation on your line and at your station before you travel.
The Mayor of London, Boris Johnson, said: "As we saw in the last strike, the belligerent actions of the Union leaderships will not bring London to a halt. They may disrupt Londoners, but they will not stop us from getting around our city. We will keep London moving.
"We are expending every effort to give people alternative ways of getting around - boosting river and bus services, holding back road works and encouraging people to cycle.
"This strike is pointless, and I hope that this time - when Londoners beat the strike once again - the RMT and TSSA leaderships will see sense and return to talks to avert further disruption."
Transport Commissioner Peter Hendy said: "There is no need for this strike at all, and we continue to make every effort to avoid a dispute. Despite the RMT and TSSA leaderships saying this is about safety, they have failed to raise a single safety-related point with London Underground in hour upon hour of talks, and have not responded to our request that they set out their specific safety concerns.
"The changes we are making are essential - due to the success of Oyster just one journey in twenty now involves a ticket office, and some ticket offices sell fewer than ten tickets an hour. We have explained that the changes come with no compulsory redundancies and no loss of earnings, and mean that stations will remain staffed at all times and every station with a ticket office will continue to have one. Still the union leaderships are intent on disrupting Londoners.
"Journeys will be more difficult, and we regret that, but they will not stop London from moving. Ninety three per cent of our customers beat the strike using public transport last time, and we will be boosting services to allow them to do so again."
