Thanks for that. Interesting. Not surprised to see the whole of the Victoria Line showing hot or very hot. Some surprises on other lines. Any idea why, for instance, The Piccadilly Line cools down round Covent Garden?
I was on one of the swish new Victoria Line trains today. You know the ones that blow air through vents above the windows. I couldn't believe it today, though, when I realised it was blowing hot air (yes HOT, not warm).
The trouble is the vents only let through the air in the tunnels, which is hot. I think TFL are really struggling to develop a way to cool the air as it goes through the vents.
