Air Conditioned Tubes trialled

Trials of the new air conditioned London Underground carriages are taking place up in Leicestershire today. The BBC reporter is filmed showing temperatures on board at around 17 degrees centigrade, so that will be a relief for many commuters when they are rolled out on the Metropolitan Line in September 2010.


The trials are expected to finished by the end of this year. Then, all going well with the Metropolitan launch, the new stock will then be released on the District, Circle and Hammersmith & City lines.


Not only will the new S stock be cooler, the trains will be larger and longer with capacity increased by nearly 20%. Roll on the launch, although cooling deep level lines like the Northern and Victoria will still be challenge.
