Designs for a new generation of Tube trains for London's Piccadilly Line, which will replace the existing 1970s fleet, have been unveiled.
Ninety-four new "fully walk-through" trains with air-conditioning and more space, will replace the 50-year-old stock, Transport for London (TfL) said.
The trains will also be lighter, more environmentally-friendly and future-proofed for a longer life, TfL added.
