According to Transport for London, the New Tube will be introduced first on the Piccadilly line, followed by the Bakerloo, Central and Waterloo & City lines. Its innovative design will also allow for air-cooling for the first time on deep-level sections of the Tube.
The train - designs for which are part of a new public exhibition at King's Cross St Pancras Underground station - also features improved accessibility, with step free access from the platform as well as walk-through carriages and wider doors.
