Measuring Air on the Tube

Good to see this couple on the London Underground this morning measuring air at the foot of escalators at Holborn. The blades in the little "windmill" thing were spinning around like mad, making this area seem positively breezy in comparison to the stuffy air at platform level.


Hopefully, this is a sign that TfL are working on improving the temperature at deep level platforms and trains running through them, despite cooling budget cuts. The Piccadilly, Central, Northern, Bakerloo and Waterloo and City lines were all marked as "high risk" from a heat point of view, if commuters got stuck on a stalled train.

The first air condtioned Tube train was launched earlier this week.
