At time of writing, the Tube strikes announced to run over the next fortnight are due to go ahead. Here's what you need to know for if they do.
The Tube strikes announced to run from 9.30pm on 4 Feb until the morning of the 7 Feb are set to go ahead. Talks between TfL, RMT and TSSA have broken down.
When are the strikes happening?
The strikes are set to run for 48hrs each: the first from 9.30pm on Tuesday February 4th until the morning of the 7th, and the second from 9.30pm on the 11th, until the morning of the 14th.
What lines will be affected?
All of them. TfL expects the Tube to run, but with a 'severely reduced service'. As ever, it's wise to check before you travel. TfL have provided a guide to the services which they intend to run during the strike. Services will only run between 7am and 11pm on 5 and 6 Feb.
How about the rest of the transport network?
Expect knock-on delays at interchanges with other services, such as the Overground and DLR. Other services will be busy as commuters move elsewhere. Some stations will not be served during the strike. See TfL's guide for more information.
What if I get stuck?
As well as the TfL website, there is a live travel news Twitter feed which will be updated throughout the strikes. In addition, hundreds of 'ambassadors' will be spread across the underground network, offering travel advice to those who need it.
Any chance this might be called off?
Yes, there is. Talks are ongoing, and the Mayor has just made the offer to meet Bob Crow (leader of the RMT union) to discuss the matter if they cancel Tuesday's strike. Barring a last-minute change of mind, no.
There is a 24hr strike on Tramlink services on Wed 5 Feb too. Again, it would be wise to check before you travel.
