Transport for London (TfL) and Siemens Mobility presented the detailed design of the future trains for the UK capital's Piccadilly line in a virtual launch event on 4 March. A GBP1.5bn (EUR1.74bn) contract for the 94 new trainsets was awarded in November 2018, to replace the ageing Metro-Cammell 1973 Stock fleet which entered service in 1975. The new vehicles are based upon the Inspiro platform, variants of which are in service in Warsaw, Sofia and Muenchen. With wider doors (1690mm and all doubles, compared to 1300mm on the 1973 Stock, which also has 680mm-wide single doors at the carriage ends) each train is also longer at 113.7m. A new multi-articulated walk-through design reduces the number of bogies, so this larger footprint promises a 10% capacity increase per train.
