New Tube for London

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

The Deep tube programme (DTP) originally covered the replacement of the trains and signalling on the Bakerloo and Piccadilly lines, and had been expanded to cover rolling stock requirements arising from the planned Northern line extension to Battersea, the eventual replacement of Central line trains and proposed increased service frequency on the Northern and Jubilee lines. The EVO tube concept design, a lighter articulated train with walk-through cars, was introduced early in 2011.Siemens presented a response in 2011, a design with the weight reduced by 30 tonnes (29.5 long tons; 33.1 short tons) and energy consumption reduced by 17 per cent, thus generating less heat to be dispersed in the tunnels. The trains would have a lower floor and 11 per cent higher passenger capacity than the current tube trains. Siemens presented a mock up of its Inspiro design at The Crystal between October 2013 and January 2014.

In early 2014 the Bakerloo, Piccadilly, Central and Waterloo & City line rolling stock replacement project was renamed New Tube for London (NTfL) and moved from its feasibility stage to the design and specification stage. The study had shown that, for new generation trains and re-signalling:
