A/C comes to the London Underground

Some trains on London's Underground will soon be cooling off a bit as the Tube adds new, air-conditioned trains to its lines. The new models, unfortunately, are too large to fit some of the deeper routes, so blessed A/C is coming to only about 40 percent of the total network.

In a separate chilling initiative, London is looking into using underground rivers and other water sources that may help cool the air in overheated stations — this method is already being used at Victoria Station.
