London Underground (LU) has introduced new designs for the ‘New Tube for London’, which comprises the next-generation trains that are expected to start service from mid-2020.
LU will first introduce the new trains on Piccadilly line, before bringing them on the Bakerloo, Central and Waterloo & City lines.
The new design features enhanced accessibility, with step-free platform access, walk-through carriages and wider doors.
In addition, the new trains will have air-cooling for the first time on deep-level sections of the Tube.
London Mayor Boris Johnson said: "From Greenford to Gants Hill, from Alperton to Arnos Grove, they will ferry millions of people across our city, more comfortably, reliably and stylishly than ever before."
LU plans to construct 250 such trains with the proposed designs. Transport for London (TfL) has collaborated with design specialists PriestmanGoode to ensure a balance between the design and functionality of the train.
London Underground managing director Mike Brown MVO said: "Londoners are already seeing huge improvements on the Tube network, with faster and more frequent journeys on the Jubilee and Victoria lines, the modernisation of the Northern line nearing completion this year, and new walk-through, air-cooled trains on the Circle, Hammersmith & City, Metropolitan and part of the District lines.
"The New Tube will take the improvements to the next level."
The trains are expected to increase the capacity of the Central and Bakerloo lines by 25% and the Waterloo & City and Piccadilly lines by 50% and 60% respectively.
The tender for the project is expected to be issued in early 2015 and the contract for construction of the new trains is due to be awarded in 2016.
