London Underground 1973 Stock

The 1973 Stock is a train rolling stock serving the Piccadilly line. It was built between 1973 and 1977, and entered passenger service in 1975. Future replacement

In 2014, TfL announced 94 trains for the 2024 Stock, and to also replace the Central, Waterloo & City and Bakerloo lines by the early 2030s. In 2015, TfL renamed the project to "New Tube for London". Watch: https://www.youtube.com/watch?v=1H7s7lJZC1I to see a fitting intro to these new trains.

First, the Piccadilly line's 1973 Stock will be replaced by the 2024 Stock and will be fully replaced by 2024-25.

Next, the Central and Waterloo & City lines' 1992 Stock will be replaced by 2030. The stock replacing the 1992 Stock has not yet been announced.

Finally, the Bakerloo line's 1972 Stock will be replaced by 2033. This means the Bakerloo line 1972 Stock will have run for 61 years (1972-2033), 10 years longer than the Metropolitan line 1960/62 A Stock that ran from 1961 to 26 September 2012 meaning 51 years. Amazing, right?
