I very much enjoyed this "weather forecast" at Kentish Town the other week…
And why so windy? Well, that'll be the piston effect: moving trains pushing air through tunnels before them whilst simultaneously drawing air down from the stations and through vents behind.
A London Walk costs £10 – £8 concession. To join a London Walk, simply meet your guide at the designated tube station at the appointed time. Details of all London Walks can be found at www.walks.com.
