London Underground (LU) has unveiled the design for the new automatic Tube train, which will come in to service from the mid-2020s.
It will be introduced first on the Piccadilly line, followed by the Bakerloo, Central and Waterloo & City lines.
When the new trains first enter service they will have an operator on board, but they will be designed and built to be capable of fully automatic operation.
The design will allow for air-cooling for the first time on deep-level sections of the Tube.
The train features improved accessibility, with step free access from the platform as well as walk-through carriages and wider doors.
Transport for London (TfL) has worked with transport design specialists PriestmanGoode on the new train.
Mike Brown, managing director of London Underground said: “The design respects the past but also looks to the future with the very latest technology; including walk-through carriages and wider doors to enable people to get on and off quickly and air-cooling for the first time on the deep level lines.”
LU said the trains will enable faster and more frequent services, increasing capacity on all four lines:
- The Central line by 25%
- The Bakerloo line by 25%
- The Waterloo & City line by 50%
- The Piccadilly line by 60%.
A formal invitation to tender for the manufacture of the trains is expected to be issued in early 2015 and a contract awarded in 2016. The first train is expected to come into service on the Piccadilly line in 2022.
