Transport for London (TfL) said the walkouts are expected to affect several key routes across the capital, with no service planned on the Circle line and Piccadilly line throughout the RMT strike periods. Parts of the Metropolitan line between Baker Street and Aldgate and the Central line between White City and Liverpool Street are also expected to be suspended.
Although services will continue to operate on other Underground lines, TfL has cautioned that service levels will vary considerably across the network. Trains are expected to start later and finish earlier than usual, while only limited services are likely to operate before 6:30 a.m. on both strike days.
Passengers have been advised to complete their journeys before 9 p.m. as services wind down in the evening.
The disruption is expected to have a significant impact on commuters and visitors, particularly those traveling to and from central London and Heathrow Airport, which is normally served by the Piccadilly line.
TfL expects normal Underground operations on June 1, June 3 and June 5, but warned that stations and trains on operating lines could be considerably busier as passengers seek alternative routes.
Other transport services, including the Elizabeth line, Docklands Light Railway, London Overground, buses and trams, are expected to run normally. However, increased demand is anticipated across the wider transport network.
Transport officials are encouraging customers to check service updates before traveling and use journey planning tools to identify alternative routes. Travelers are also advised to allow extra time for their journeys as crowding and delays are expected throughout the day.
The strike action comes during a busy period for London tourism and business travel, with thousands of residents and visitors likely to be affected by the reduced Underground service.
The strike follows a major two-part Tube strike on April 21 and 23, 2026, which was followed by a bus strike on April 24, and a 24-hour Tube driver strike on May 19-20 and May 21-22 in response to London Underground’s push for a compressed four‑day working week.
