The lack of widespread regenerative breaking in subways is leading to commuters' lungs being filled with brake dust, in addition to heating up the stations, which is a problem in summer. This is really bad and embarrassing. Rail moves far too slow when it comes to adopting new tech.

    They've managed to install it on a bunch of trains in the Barcelona metro and it's helped dropped the temperatures by around 1.5c.

    I know Tfl has also put it on a couple of trains over the years but yeah we're still lacking a broader rollout.
