When will second day of London Tube strikes take place this week and which lines are affected?

Two 24-hour Tube strikes are going ahead this week as last ditch talks to reach an agreement in the long-running dispute over working hours did not produce results.

Talks between Rail, Maritime and Transport union (RMT) and Transport for London (TfL) on Monday failed to resolve the dispute, it was confirmed on Monday afternoon.

This means that members of the union have walked out on Tuesday, with further action planned for Thursday, in a move which threatens huge travel disruption in the capital.

The strikes are in response to issues including a new four-day week which the union says its members oppose. The drivers’ union Aslef has accepted the new arrangements.

Claire Mann, Transport for London’s (TfL) chief operating officer, said: “We still believe that the points they have raised can be worked out in time, through more detailed discussions and we are continuing to talk to the union’s representatives to find a way to avoid disruption to London.”

TfL has advised passengers to check before they travel if the strikes go ahead.

A union spokesperson said: “Our members have raised serious concerns around fatigue, longer shifts, reduced flexibility and the impact these proposals could have in a safety-critical role.”

RMT were due to walk out for 24 hours from midday on Tuesday 19 May, and again on Thursday 21 May but the action was called off at the last minute.

Strikes scheduled for June 16 and 18 have also been called off, but the union announced the new, earlier 24-hour strike dates of June 2 and 4 if the dispute remains unresolved.

Claire Mann, TfL’s chief operating officer, said the proposals for a four-day working week allow the company to “offer train operators an additional day off, whilst at the same time bringing London Underground in line with the working patterns of other train operating companies, improving reliability and flexibility at no additional cost”.

She added: “The changes would be voluntary, there would be no reduction in contractual hours and those who wish to continue a five-day working week pattern would be able to do so.”

TfL has set out what travellers can expect during strike days, with certain lines more affected than others. Here’s what you need to know:

What dates are the Tube strikes?

What time will the Tube shut and reopen?

The planned strike action will take significant parts of the network out of action for two days, lasting 24 hours – or the entirety– of each of them.

On the Tuesday and Thursday, travellers can expect virtually no service before 6.30am, or after 9pm. There will be significant disruption in the morning, afternoon and evening.

Which Tube lines will be affected?

TfL says the strikes will affect the whole Tube network, but a reduced service will still run on most lines with significant disruption.

However, there will be no service on the:

Elizabeth line, DLR, London Overground, and tram services will be running normally on strike days, but are likely to be very busy.
