Tube strikes will affect commuters over several days from 7 January as London Underground workers walk out over pay.
A strike by Rail, Maritime and Transport union (RMT) members is set to cause heavy disruption to Tube services until 12 January.
Union members from various departments of London Underground will strike on different days, meaning there will be “little to no service” on strike days.
The industrial action comes after RMT members voted against the latest pay offer of 5% at the end of last year.
Transport for London (TfL) has urged passengers to only travel on the strike days if their journey is “essential”.
Other TfL workers on bus, DLR, London Overground and Elizabeth line services won’t be striking, but those services will be busier and affected by station closures at stations that also serve London Underground lines.
One-way or queueing systems may also be in place, it says.
Here is a full list of the services affected by strikes and when.
Sunday 7 January
TfL has urged customers to complete Tube journeys by 5.30pm as services will end earlier than normal.
Lines serving the Emirates Stadium are expected to remain open later to accommodate fans watching the Arsenal v Liverpool FA Cup tie. Those services will begin to wind down from 7.30pm.
It is only the Underground that will be affected on Sunday evening. The Elizabeth Line, London Overground and DLR services are all expected to run without disruption.
RMT members in London Underground’s network control centre are the workers taking action.

How can I stay in the loop?
You can use the TfL’s journey planner to see when trains are running.
Be sure to check it closer to the time you plan to travel, as it will be updated regularly.
What has been said about the strikes?
Announcing the strike action last month, RMT general secretary Mick Lynch said that Tube workers were “not going to put up with senior managers and commissioners raking it in while they were given modest below inflation offers”.
“The refusal of TfL to restore staff travel facilities and create a two-tier workforce is also unacceptable,” he added.
“Our members have made it clear that they are prepared to take action and we urge TfL to improve their offer to avert disruption in the capital.”
Glynn Barton, TfL’s chief operating officer, said: ”We are disappointed that RMT is planning strike action in response to our offer of a 5% pay increase.
“We have been clear throughout our productive discussions with our trade unions that this offer is the most we can afford while ensuring that we can operate safely, reliably and sustainably.
“We encourage the RMT to engage with us to avoid disruption for Londoners. We would like to advise anyone travelling during the strike days to check before they travel.”
