A new tube strike has been announced by rail unions less than a fortnight after they cancelled planned February strikes .
Union general secretary Mick Cash said staff have no choice but to walk out after talks in January did not come to a conclusion and displacement of staff will go ahead.
He said: "London Underground Limited (LUL) have now written to us confirming that they will be bulldozing through the displacements regardless."
London suffered during the January strikes
Mr Cash added: "RMT negotiators have made strenuous efforts through the ACAS machinery to resolve this dispute but the door has been slammed in our faces.
"To up the ante, LUL have now written to us confirming that they will be bulldozing through the displacements regardless.
"Let us be in no doubt, if LU are allowed to get away with this move on the Central line they will start shunting drivers around the combine at the drop of a hat regardless of the consequences."
Commuters are once again facing delays in their journey, after January strikes crippled the capital.
The fear of February strikes was initially diminished after the union cancelled them when TfL said they will be hiring some of the front line staff which were axed as part of cutbacks in the company, a decision the union had pushed for.
But Mr Cash said of the new strikes: "Our members will be sent out from pillar to post to plug gaps that are solely down to staffing shortages.
"With massive budget cuts in the pipeline at LU this is a straw in the wind as to how the company expects to operate in the future.
"Staff across London Underground are angry and the company would be wise to recognise that."
Here's what you need to know about how your commute is affected.
Where are the strikes taking place?
The strikes will affect the central line, particularly on the Hainault, Leytonstone and Loughton, where staff members have been told "not to book on any shifts".
When are they going ahead and how long will they last?
They will go ahead from 9pm on Tuesday, February 21 for 15 hours, meaning normal service will resume at 8.59pm on Wednesday February 22, as it does not account for the hours the underground is not in action overnight.
Why are they happening?
They come as RMT announce they are worried staff shortages will lead to train conductors being asked to "plug the gaps" in other roles .
