Commuters across London faced major transit disruptions on Monday, June 1, 2026, due to multiple track and signal failures across the Transport for London network, right as the city braced for a fresh round of Tube strikes.
A series of infrastructure issues crippled morning transit, including a signal failure at Brixton that partially suspended the Victoria line and a faulty train at Hackney Wick that caused severe delays on the Mildmay line.

A fire alert at Bank entirely shut down the Waterloo & City line and halted parts of the DLR, while track and signal faults triggered severe delays on the Bakerloo and Jubilee lines, forcing passengers into long queues outside London Bridge station.
Outside the Underground network, a points failure near Slough caused major cancellations and revisions for Great Western Railway passengers and severe delays on the Elizabeth Line between Hayes & Harlington and Reading.
Tickets were widely accepted on London buses and alternative rail services as Transport for London (TfL) scrambled to manage the widespread network congestion.
The current travel chaos precedes two planned 24-hour walkouts by drivers belonging to the Rail, Maritime and Transport (RMT) union, scheduled from midnight to midnight on Tuesday, June 2, and Thursday, June 4, 2026.
Last-ditch conciliation talks involving Acas were held on Monday in an eleventh-hour attempt to resolve the dispute over the voluntary introduction of a compressed four-day working week.
TfL officials expressed regret over the upcoming industrial action while maintaining that discussions remained open to prevent further transit issues.

"We still believe that the points they have raised can be worked out in time, through more detailed discussions and we are continuing to talk to the union’s representatives to find a way to avoid disruption to London," said Claire Mann, TfL’s chief operating officer.
While TfL hopes to operate at least half of the Tube services, the Circle and Piccadilly lines will close completely, and partial suspensions will hit the Metropolitan and Central lines.
Services on strike days will start late and finish early, running only between 6:30am and 9:00pm, with spillover disruption expected on the mornings of June 3 and June 5, 2026.
The RMT union has voiced strong opposition to the proposed operational changes, citing potential safety risks for its members.
"Our members have raised serious concerns around fatigue, longer shifts, reduced flexibility and the impact these proposals could have in a safety-critical role," said an RMT spokesperson.
In contrast, the drivers' union Aslef has already accepted the new voluntary arrangements, viewing them as a benefit for participating staff.

Aslef stated that the voluntary compressed four-day week gives participating staff an extra 35 days off a year in return for some "fairly minor changes to working conditions."
