Boris Johnson unveils plans for new air-cooled tube trains

Plans for a new generation of London Underground trains have been unveiled.

The trains will include air-cooling for the first time on deep level sections of the Tube.

LU said the new Tubes, which will come into service from the mid 2020s, would "change the face of travel" on the underground.

The trains, which will be introduced on the Piccadilly Line, followed by the Bakerloo, Central and Waterloo & City Lines, will feature walk-through carriages and wider doors. Words:PA

Managing director Mike Brown said: "The faster, more frequent and more reliable services will help us keep pace with London's growing population.

London's Mayor Boris Johnson said the "innovative" new trains will ferry millions of people across the capital more comfortably, reliably and stylishly than ever before.

LU said the new trains, which will serve London for more than 40 years, will have an "operator" on board.

Mick Cash, general secretary of the Rail, Maritime and Transport union, said: "RMT is deeply concerned that the design of these new trains appears to allow for driverless operation.

"RMT has made it clear repeatedly that any moves towards the lethal and cash driven nonsense of removing drivers on London Underground would be resisted through the most robust industrial and political campaign of opposition."
