    Yesterday a coughing fit spread on a northern line train whilst a passenger commented their newspaper and turned dirty in the short time it had been down there

    At finsbury park a balloon caught hanging on the victoria line platform is now covered in dirt

    Just how bad is it down there ?

    In today's Financial Times there is a full-page piece on air pollution in the tube.

    nothing lie as bad as it used to be, working as a gurad in the 90s you could never consider going out after work without having a shower first, the water used to be black around your feet.

    Blow your nose after a shift driving and it'll be black

    One of the sources of pollution is particles shed during friction braking, but this should be decreasing on those lines as the current trains mainly use regenerative braking. The Piccadilly and Bakerloo are probably worst for this as they still have older trains. Another one is wheel/rail wear, which is probably worse on the Northern than on the Victoria which was built later and efforts made to avoid tight curves. This, and other sources notably skin cells and fluff shed by passengers, will probably increase in line with the numbers of trains and passengers.

    According to Wednesday's FT (paper version, in front of me now), but see thread

    https://www.railforums.co.uk/thread...n-the-london-underground.194732/#post-4276639

    the Piccadilly and Bakerloo are actually the 'best two' (albeit of a bad bunch) of the deep lines.
    The worst is the Central, specifically between Lancaster Gate and Queensway, at nearly 8 x the WHO safe limit and - yes - next worst is the Victoria, at 6 and a bit times the limit.

    It would be interesting to see how many staff have retired early with diseases which could be linked to air pollution compared with people following other careers.
