Transport for London (TfL) is asking customers to check before they travel ahead of planned strike action on the London Underground by RMT union Tube drivers. 

TfL is working hard to resolve the dispute, with dialogue with the union ongoing, and says it will operate as many services as possible should strikes go ahead. 

TfL is urging the union to call off their action and continue to work together on proposals to pilot a four-day week for train operators.

Strike action affecting the London Underground has been called between Tuesday, 21 April and Friday, 24 April. 

Should the strikes go ahead, there is expected to be some service on most lines, but with significant disruption. 

The level of service on each line will vary across the London Underground network. 

On these days, all other London Underground staff will be working, and other TfL services including the Elizabeth line, DLR, London Overground and Trams will be running normally. 

However, TFL says,  they are likely to be very busy.

The vast majority of buses will be running normally throughout these strikes, but seven routes operated by Stagecoach will be affected by a separate strike between 5am on Friday, 24 April and 5am on Saturday, 25 April. Other buses will run as usual.

This strike action, the first in a series of planned strikes between April and June, will begin at 12pm on Tuesday, 21 April, with a normal service expected until mid-morning. 

The action will finish at 12pm  on Friday, 24 April and customers should expect disruption into the afternoon and early evening. 

ustomers are advised to check their travel daily on TfL Go.

TfL put forward a proposal to its trade unions for a four-day working week for train operators in March 2025, which it says is "similar to the working patterns offered by most other train operating companies".

 Since then, TfL has been engaging with the unions on how best to introduce the new working pattern including a pilot for train drivers on the Bakerloo line only. 

TFL said: "The changes to working patterns would be voluntary, with no reduction in contractual hours and those who wish to continue working a five-day week pattern would be able to do so. 

"The changes would help TfL to improve reliability and enable a modern and efficient service while creating no additional cost."

Claire Mann, TfL's Chief Operating Officer, said: "We have set out proposals to the RMT for a four-day working week. 

"This allows us 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.

"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. 

"We urge the RMT to call off this action, which will disrupt Londoners, and continue to engage with us. 

"If this strike action goes ahead customers should check before they travel as on some days during the strike, there will be significant disruption and the level of service we can provide will vary across lines."
