A 24-hour Tube strike is still set to go ahead on Thursday due to a row over new timetable changes.
The Rail, Maritime and Transport (RMT) union is holding a walkout on Thursday 14 June, pending further talks with Transport for London (TfL).
Here's what we know so far about the likely disruption…
Which line will the Tube strike be on?
The RMT drivers will walkout on 14 June on the Jubilee Line.
I thought the Tube strikes were called off last week?
They were – sort of. A Jubilee Line walkout planned for last week on the 6 June by both the RMT and train drivers' union Aslef was suspended after talks. Meanwhile, a separate row involving Aslef on the District Line has also cooled off for now, with action there suspended.
But the RMT said the second 24-hour Tube strike planned for Thursday 14 June remains on pending further talks with TfL.
So how much disruption are we talking?
At the moment, if the walkout goes ahead we could see the whole of the Jubilee Line disrupted, with a possibility of no service.
Will anything run?
Other lines will operate as normal, and extra buses will be run along key routes to help Londoners get around, though TfL has also warned these are expected to be "very busy".
What stations will be busier than usual?
Stations expected to be busier than usual because of the Jubilee troubles include West Hampstead Thameslink, Hendon, South Hampstead, West Ham and Stratford.
Why is the strike happening?
TfL is making timetable changes so Jubilee Line passengers can benefit from quicker and more frequent trips, but the unions weren't happy about it. They say the imposition of new timetables has overridden current rostering agreements.
The RMT's general secretary Mick Cash said drivers were angry about "the impact on work-life balance", while Aslef said the new rosters increase the number of Saturday shifts drivers are required to work, and breaks a previous agreement to maintain the same percentage of rest days as the service expands.
Yes, TfL extended the peak service on the busiest sections of the Jubilee Line by an hour this month, which it said will provide benefits for up to 320,000 customers each day.
The new timetable extends the 30 trains per hour service in both peaks – the morning one starting from 7.30am and the evening one starting from around 4.15pm – by at least an hour between West Hampstead and North Greenwich.
Will the Tube strike interrupt the quicker services on the Jubilee then?
No, the new timetable has already been rolled out, but a resolution to the row will need to be agreed if TfL is to stave off the threat of more Tube strikes.
Nigel Holness, London Underground's director of network operations, said: "The new Jubilee Line timetable will benefit thousands of passengers every day as we extend the most frequent, peak-time service from 30 minutes to two hours.
"We have agreements with our trade unions on the amount of weekend working we ask our drivers to do, and implementing this timetable keeps us well within those agreements. We encourage RMT to continue working with us in order to deliver these huge benefits to customers rather than calling for unnecessary industrial action."
Will there be more travel guidance?
TfL travel ambassadors will be at key locations to provide travel information and advice for affected customers. More details from TfL on the disruption expected from the strike can be found here.
Any chance of the strike getting called off?
Fingers crossed. The changes are higher considering last week's action was suspended, and TfL has confirmed it is planning to meet the RMT this week for talks.
Enough progress was made in discussions last week to call off that industrial action, so TfL will be hoping it can carve out a resolution with the RMT to stave off Thursday's strike too.
