Agreed, but here it is done highly effective. The 1.8 degree temperature difference is a huge plus too - they can now also save serious amounts of power on ventilation.
TfL, you listening?

The heat on the underground is mad, makes it so hard to dress for the weather. Go out in a coat because it's cold then get down on the central line and everyone is sweating hard

The warming is global, tubes included.

Agreed. I think TfL actually has begun looking into it but it’ll probably take years before the temperature is going to drop.

Victoria, Circle, District, Hammersmith and City, Metropolitan and the new Piccadilly Line trains (due soon) all have regenerative braking. The rest will follow as new trains are procured.

As anyone who travels on the Victoria line in the summer will tell you: it helps, but not much.
