Londoners face almost a week of travel disruption when Underground workers go on strike next week.
There will be limited or no services for several days, and those services that are still running are expected to be busier than usual.
Members of the Rail, Maritime and Transport union (RMT) voted overwhelmingly for strike action after nine months of negotiations failed to resolve a long-running dispute over pay and conditions.
Further talks have also failed to end in an agreement, meaning industrial action is set to cause chaos in the capital.
Here is all you need to know.
When are strikes planned?
Strikes are planned from midnight on Sunday 7 September to 11.59pm on Thursday 11 September.
There is separate planned industrial action on 5 and 6 September, but this is not expected to cause disruption on Transport for London (TfL) services.
The other days, however, will see delays across every underground line and the Docklands Light Railway (DLR).
What's running - and what's not?
Sunday 7 September:
• Disruption across the entire Tube network, with limited services running

What about the Elizabeth Line and Overground?
The Elizabeth Line, London Overground and trams will be running on strike days. London's bus network is also expected to be running a full service.
However, TfL warns other services will be extremely busy and trains may be unable to stop at all stations or run to their normal destinations.
From Monday 8 and Wednesday 10 September, the Elizabeth line will not stop at the following stations before 7.30am and after 10.30pm:
• Liverpool Street
• Farringdon
• Tottenham Court Road
On Tuesday 9 and Thursday 11 September, trains will not stop at the same stations before 8am.
How to get around during the Tube strike
As always during industrial action, TfL urges commuters to plan ahead and allow extra time for their journeys.
To do this, use TfL's journey planner, or apps including City Mapper.
Cycling or walking is also recommended by TfL, with Santander, Lime and Forest bikes available to hire across the capital, as well as electric scooters in some London boroughs.
Have any events been cancelled?
As a result of the strike, Coldplay have rescheduled the final two dates of their 10-show run at Wembley Stadium.
The band posted a statement on social media to say their Music Of The Spheres shows on 7 and 8 September have been rescheduled to 6 and 12 September respectively.
"Without a Tube service, it's impossible to get 82,000 people to the concert and home again safely, and therefore no event licence can be granted," the band said.

Other concerts and events are, however, still planned to go ahead around the capital.
On 7 and 8 September, Post Malone is due to perform at Tottenham Hotspur Stadium as part of his Big Ass World Tour.
Events for the BBC Proms will also run throughout the week of strikes at the Royal Albert Hall until the last night on 13 September.
