ASLEF union members are due to strike on Monday, 8 April and Saturday, 4 May, impacting Tube services in the capital, with customers urged to check before they travel.

While Londoners will still be able to travel on London Overground, Elizabeth line, DLR, Tram and IFS Cloud Cable Car services, they may be subject to last-minute changes, and TfL expects these services will be much busier than usual and queuing systems may be in place.

Expected disruptions:

• On Monday 8 April, severe disruption is expected, with little or no service expected on some underground lines, and Tube services will start later than normal on Tuesday 9 April, with a good service expected by mid-morning 
• On Saturday 4 May, severe disruption is expected, with little or no service expected on some underground lines, and Tube services will start later than normal on Sunday 5 May, with a good service expected by mid-morning

London buses are also expected to operate normally during this planned strike action.

Nick Dent, Director of Customer Operations for London Underground, said: "ASLEF is planning strike action on the London Underground on Monday 8 April and Saturday 4 May.

"We are encouraging ASLEF to continue engaging with us so the strike action can be avoided.

"We would like to advise anyone travelling to please check before you travel, expect services to be busy and please allow extra time to complete your journeys."

Strike action is disruptive, and TfL continues to meet the ASLEF union at the conciliation service ACAS this week in the hope that this strike can be called off the network says. 

TfL will be supporting customers to choose alternative travel routes where possible through a comprehensive communications campaign, which includes station announcements, posters, emails and social media.
