Tube strikes look likely to bring London to a halt next week as workers walk out over job losses and ticket office closures.
TfL has updated the London Underground (LU) map, greying out all the stations that will not be in use as industrial action goes on between Sunday, February 5 and Wednesday, February 8.
LU said if the strikes go ahead there will be a significant impact on Tube journeys from 6pm on Sunday until around 11am on Wednesday.
Many Tube stations, including most of those in Zone 1, will not open or, in some cases, may open or close at short notice.
The unions have warned that the loss of more than 800 jobs is affecting safety and want LU to reinstate more than it is currently offering.
LU chief operating officer Steve Griffiths said: “If the strike by the RMT goes ahead, we will be working hard to minimise disruption as much as possible and doing our best to help customers travel around the capital.
“Our plan is to use the services we are able to run to get as many people as close to central London as possible.
“We have made a proposal to both unions in order to end this dispute and will be recruiting at least 650 new station staff this year, of which 325 will be additional new roles.
“I urge the RMT to keep talking with us and not disrupt the lives of Londoners.”
