A 24-hour strike by members of the National Union of Rail, Maritime and Transport Workers (RMT) has severely disrupted London Underground services. The industrial action, which began on Tuesday, 21 April 2026, is affecting all Tube lines.
The RMT union has stated the walkout is over unresolved disputes concerning pay, working conditions, and potential job losses. Transport for London (TfL) has advised passengers that Tube services are either suspended or running with severe delays, and to seek alternative travel methods.
Major stations across the network are experiencing significant crowding. TfL is reporting that bus, DLR, and London Overground services are much busier than usual, with some roads facing increased congestion. The strike action is expected to continue until midday on Wednesday, 22 April 2026.
This is the latest in a series of industrial disputes affecting London's transport network. Negotiations between the RMT union and TfL management were ongoing prior to the strike deadline but failed to reach an agreement.
