Tube strike today London: what is running, exact timings and how to travel on 21 April

Today, Tuesday 21 April 2026, a 24-hour tube strike today begins at 12:00 across parts of the London Undergroundnetwork, with disruption building steadily through the afternoon rather than affecting the morning peak. The action, part of the ongoing tfl strikes April 2026, is being carried out by members of the Rail, Maritime and Transport union and affects both entire lines and key central sections; The WP Times reports, citing official updates from Transport for London.

For passengers asking is there a tube strike today or are tube strikes going ahead, services begin to deteriorate from midday, with the most significant disruption expected between 14:00 and 20:00. This is not a complete shutdown. Instead, the underground strike creates a fragmented network where some routes are unavailable, others run with reduced frequency, and journey times increase sharply where interchanges are required.

The operational timeline is consistent across the network. Between 06:00 and approximately 11:30, services run largely as normal. From 12:00, cancellations begin to appear across multiple lines. By early afternoon, gaps between trains widen and reliability falls. Between 14:00 and 20:00, the system reaches peak disruption, particularly in central London, where reduced capacity and high passenger demand combine. After 20:00, some stabilisation begins, although services remain irregular into the evening and overnight.

Network status during tube strikes today

This pattern explains why searches such as tube strikes today, strikes London and are the tube strikes going ahead are concentrated on central corridors: disruption is not evenly spread but focused where the network is most dense. Movement across London today depends on route selection rather than proximity. The most reliable east–west connection is the Elizabeth line, which remains largely unaffected and effectively replaces parts of the Central and Piccadilly lines. It connects Heathrow, Paddington, the West End, the City and Canary Wharf with significantly greater reliability than the Underground today.

The London Overground provides a second layer of resilience, particularly for journeys that avoid central London. It allows orbital travel between north, east and south London without entering the most disrupted zones, reducing dependence on interchanges.

In central London, walking becomes a primary mode rather than a fallback. Distances between major stations are short and predictable. Oxford Circus to Soho can be covered in under ten minutes, Bank to Liverpool Street in around ten to twelve minutes. During the peak disruption window, walking these sections is often faster than waiting for a delayed train.

How to travel by zone

In Zone 1, the split Central line and closed Circle line remove key cross-city links. The most effective routes combine the Elizabeth line with short walking segments. In Zone 2, congestion increases as passengers reroute around the centre, making the Overground a practical alternative. In outer zones, services continue but with reduced frequency, so remaining on a single line is often the fastest option.

Heathrow and west London

The closure of the Piccadilly line is one of the most significant impacts of the tube strike today.

Passengers travelling to or from Heathrow should use the Elizabeth line or National Rail services to Paddington. Interchange pressure at Paddington is expected during peak hours.

City and Canary Wharf

Access to the City is constrained by Central and Metropolitan line disruptions. The Docklands Light Railway continues to operate and provides access across Docklands, while the Elizabeth line remains the most reliable east–west link. Short walking connections between Bank and Liverpool Street are likely to be faster than attempting Underground transfers.

Surface transport conditions

Road congestion increases from early afternoon, particularly along Oxford Street, Victoria and Holborn. Bus journey times are expected to extend by 20–40%. Cycling remains the most stable option where available.

Practical travel advice today

Passengers navigating the tube strike today should prioritise timing and simplicity. Travel before 12:00 where possible. If travel is required during the disruption window, base the journey around the Elizabeth line and avoid unnecessary interchanges. Allow additional time, particularly for journeys involving central London. Check live updates from Transport for London before departure. Avoid relying on the Piccadilly and Circle lines, both of which are fully closed. Avoid complex routes that depend on multiple line changes in Zone 1. Expect longer journey times and adjust plans accordingly.

For those asking is the tube strike still on or tube strike tomorrow, the current action runs until 12:00 on Wednesday 22 April. Disruption is expected to continue into the morning peak even after the official end time. A second 24-hour strike is scheduled from Thursday, meaning further disruption under the london tube strikes April 2026 programme.

London remains operational, but the structure of movement has shifted. The Underground is functioning in parts rather than as a continuous network. Journeys that rely on alternative corridors — particularly the Elizabeth line, Overground and short walking connections — are the most reliable throughout the day.
