Tube Map shows hottest spots

TfL have revealed the hottest spots on the London Underground to identify the areas which need the most cooling. The heat map compiled on July 28 - the hottest days of last year, showed the Central Line was the warmest. Luckily it was already coloured red. That part of the network was above 30C (86F).


The baking Bakerloo Line was the next hottest. Between 4pm and 7pm, most of its stations were in the highest temperature band, although things got cooler the further south you went. Even in the coolest stations the temperature hovered at about 25C.

On the map the green areas show 26 degrees, moving up to 29 degrees in the yellow areas, with the read areas at 32 degrees centigrade.

In previous tests, temperatures in some carriages during the summer have exceeded 35C, which would make the network officially unfit for transporting cattle.

The Underground hotspots can be seen on this map and more information is on The Times.
