As for actual pollution levels then this depends on where you are on the
network. TfL don't measure enough to give a heatmap of pollution, updated
hourly. Your statistic from the Guardian sounds about right, generally
speaking though the particulates are at 10x the EU max levels.

In a communist style country you could have an army of people polishing the
tube stations and the tunnels as part of some National Service. But, in a
Western Democracy where everyone has to pay a four figure sum for rent +
travel no matter how they try and mix it, this isn't going to happen.

They have tried to create magic sweeper trains to hoover everything up but it
hasn't been a success. Really that is what is needed as well as the trains
being built to 'hoover as they go', using the air-con to filter out all the

No, the problem is ventilation.
[https://en.wikipedia.org/wiki/London_Underground_cooling](https://en.wikipedia.org/wiki/London_Underground_cooling)

In eastern europe we have very effective ventilation - for number of reasons,
one of them is that it was built much later, the other is that some of the
station were built to serve as a nuclear shelter so they had to have very safe
ventilation systems...
