What time the Tube strike is tomorrow with action planned across London Underground

Strikes are set to go ahead across the London Underground, with no breakthrough yet in talks between Transport for London (TfL) and union bosses.

Passengers have been warned of severe disruption starting at the end of November and leading up to Christmas.

TfL said the action could lead to a “significantly reduced service on these lines all day with little or no service in places”.

When will the Tube strike start?

The strikes will begin with a 24-hour walkout starting at 4am on Friday 26 November.

There will also be action overnight from 8.30pm to 4.30am each Saturday and Sunday, starting this weekend.

The Central, Jubilee, Northern, Piccadilly and Victoria lines will all be affected.

The Bakerloo, Circle, District, Hammersmith and City and Metropolitan lines could feel the knock-on effect, though no strikes are happening on the lines themselves.

There are expected to be significant delays on the Central, Jubilee, Northern, Piccadilly and Victoria lines, with little or no service in places.

How long will it last?

The action will continue every weekend until 18 December, unless an agreement is reached.

Here are the strike times in full:

Why is the strike happening?

The Rail, Maritime and Transport (RMT) union called the strikes to coincide with the reintroduction of Night Tube services on the Central and Victoria lines from the evening of Saturday 27 November, and on weekends throughout December.

TfL says drivers will have to work about four Night Tube shifts a year.

It has argued that all other Tube unions agreed to the change in rosters in May, which came after Night Tube staff were integrated into TfL’s “day Tube” workforce.

However, the RMT says the changes have resulted in “unacceptable and intolerable demands” on its members.

RMT general secretary Mick Lynch said the union “remains open for talks”, but that Tube bosses have “refused point blank to consider the serious grievances at the heart of the dispute”.

Nick Dent, director of London Underground customer operations, said: “At such a pivotal time for the capital’s recovery, we are hugely disappointed that the RMT is threatening London with this unnecessary action.

“By making changes to Tube driver rosters, we have provided greater flexibility for drivers as well as permanent work and job certainty, something welcomed by all other unions.

“The return of Night Tube is a hugely significant moment for the night-time economy and for Londoners travelling late at night who will have improved journey times and an additional safe travel option.

“We have been meeting with the RMT for a number of months through Acas to try and resolve their issues and we remain open to talking further.”
