A major tube strike today has started in London, causing serious travel problems across the city. The London Underground, managed by Transport for London, is facing reduced services as train drivers walk out.
This underground strike is part of a larger dispute between unions and TfL, and it is expected to affect commuters for several days.
What is happening in the Tube strike today
The tube strikes today began on April 21, 2026, with drivers going on strike from midday. The action will continue in phases, including another strike period later this week.
This means that the train strike will impact travel not just on one day but across multiple days, with disruptions continuing even after the strike hours end.
Most London Underground lines are expected to run limited or no services, especially during peak strike hours. Some lines may completely shut down, while others will operate with heavy delays.
Why the strike is happening
The strike has been called by the RMT union due to disagreements with Transport for London over new working conditions.
TfL has proposed a four-day working week for drivers, which would include longer shifts but more days off. While some unions support the idea, others have raised concerns about fatigue, safety, and working conditions.
Because talks between both sides have not been successful, workers decided to go ahead with the strike.
Which services are affected
The underground strike is affecting the entire London Underground network. On strike days, trains may stop early in the evening, and services may start late the next day.
Lines such as Piccadilly, Circle, and others are expected to face the biggest disruption, with some not running at all during certain hours.
However, not all transport is stopped. Other TfL services like buses, trams, the Elizabeth Line, and London Overground are still running, although they are likely to be very crowded.
How long will the disruption last
The current tube strike today is part of a bigger plan that includes multiple strike days in April, May, and June. This week’s strike will mainly affect travel from April 21 to April 24, with two 24-hour strike periods and continued disruption around them.
More strike dates are already planned if the dispute is not resolved.
What commuters should do
Passengers are advised to plan their journeys in advance and check updates from TfL before travelling. Using alternative transport options like buses, trains, or even cycling may help avoid delays, but these services are expected to be busier than usual.
