The London Underground 2024 Stock, known during development as the New Tube for London (NTfL), is a type of London Underground rolling stock built by Siemens Mobility at its facilities in Goole, United Kingdom and Vienna, Austria. It is part of the Siemens Inspiro family of metro and rapid-transport trains.
An initial batch of 94 nine-car trains has been ordered at a cost of £1.5 billion to replace 1973 Stock trains on the Piccadilly line, with options for a total of 250 trains allowing replacement of all existing trains on the deep-level Central, Waterloo & City and Bakerloo lines. The first train was delivered for testing in London in October 2024. The trains are to enter service from the second half of 2026. The trains will enter service with a train driver, with future potential for driverless operation.
