New tube for London

New Tube for London (NTfL), also known as the Deep Tube Upgrade Programme,undefined is a programme to introduce 250 new trains and signalling on several London Underground deep-tube lines between 2023 and 2033. The fully automated trains will increase capacity on the Piccadilly, Central, Waterloo & City and Bakerloo lines. The trains may not have drivers, though the ASLEF and RMT trade unions that represent the drivers strongly oppose this, claiming that such operation would be unsafe.

The NTfL will replace the 1992 Stock, 1973 Stock and 1972 Stock.
