London Underground Air Quality

I recently found myself in London and using the tube as a main form of transport.

What struck me was the pungent smell of brake linings when getting off the train.

The question is then, what sort of air quality management is happening underground?

It can't be good folks breathing that stuff during their commute, less so the workers who are subjected to a full shift of it.

Mainly the Central line with a little Circle line.

You could see a haze through the light at times.
