Wrong, wrong, wrong. This announcement is specifically about the deep-level lines. Read the details: http://www.tfl.gov.uk/campaign/new-tube-for-london

The new trains, platform-edge doors, and air-cooling are being introduced for the Central, Bakerloo, Waterloo & City, and Piccadilly lines. The tunnels and trains will still be small, there's not much that can be done about that, but they will be cooler, safer and hopefully a little less cramped, due to the extra capacity provided by walk-through carriages.

I did read the article, so must have suffered some kind of mental failure. I don't expect any real improvement in temperatures on the central line. There is nowhere for the heat to go.

(Surely puzzlement is the appropriate response to a blatant factual error, not "wrong, wrong, wrong!". I mean, I know HN is a hangout for intolerant geeks but still...)
