In their latest stand against job cuts and chnages to terms and conditions, there will be widespread travel disruption on October 4 and October 6, when Tube staff walk out.
All services in London — except for the Overground, Elizabeth Line, DLR, and trams — will be severely impacted.
One of the strike days will also clash with another strike by train drivers’ union Aslef.
So what can London commuters expect next month? Here’s what you need to know about the upcoming strikes and their impact on the London Underground.
When are the Tube strikes?
Strikes have been announced for October 4 and 6.
The industrial action on October 4 coincides with a planned strike by Aslef members, that will also impact trains travelling into London such as the Thameslink and South Eastern lines.
What will be affected?
Most underground lines will be impacted on October 4 and October 6, including:
Hammersmith & City Line
Waterloo & City Line
The Overground, Elizabeth line, DLR, and trams will not be impacted by the RMT walkout.
However, expect these lines to be much busier than usual as people find alternative ways to travel in and out of London.
Buses will also be busier than usual, meaning travellers should expect delays on most travel routes that are still operating.
You can check the TFL website for further information about disruption.
Why are TfL staff striking?
The union has been locked in a row over cuts it claims will lead to hundreds of job losses.
Safety concerns have also been raised over higher workloads, more lone working, and increased fatigue.
RMT boss Mick Lynch said: “Station staff have had enough of having their livelihoods threatened by job losses and attacks on their terms and conditions.”
He added: “Station staff have a vital role to play assisting vulnerable passengers access the network safely and ensuring that the Tube is a safe environment for passengers.
“These job cuts and attacks on conditions are going to lead to more unstaffed stations, temporary closures, and rising passenger anger.
“TfL has had its budgets slashed but the savings made by these station staff cuts will be negatable and will lead to shortages that are unacceptable.
“This strike action will lead to the Tube being shut down and we call on Mayor Sadiq Khan to meet us urgently to discuss this matter.”
