Transport for London (TfL) has revealed the underground services it hopes to run during the planned tube strikes, while still hoping the unions "do the right thing" by calling off the action.
Members of the RMT and TSSA unions are to stage two 48-hour walkouts - from 9.30pm on Tuesday (4 February) and again on 11 February. Full services are not expected to resume until the Friday mornings following the stoppages.
The strike has been called in protest at the decision to close all tube station ticket offices by 2015 with the loss of 950 jobs.
TfL has warned commuters to expect huge disruptions on the strike days but has planned a reduced service on several lines.
Talks are due to take place between TFL, London Underground (LU) and the unions with the hope the strike could yet be called off.
LU managing director, Mike Brown said: "We're committed to implement these changes without compulsory redundancies and there'll be a job for everyone at LU who wants to work for us and be flexible.
"My message to the unions' leadership is that it's not too late to do the right thing, call off this completely unnecessary strike and work with us to help shape the future of the tube."
