A 'Chesham Express' train calls at London Baker Street railway station

A short 1990s nostalgia blast showing London Transport A stock trains at Baker Street station, including one on an hour-long 'Chesham Express' service that featured a 19 minute non-stop run between Finchley Road and Moor Park stations. btw, stereo headphones are recommended as there are also some 'unusual' noises which are more easily heard with headphones (or the sound turned up loudly, which might annoy people near to you). For instance, the hum noise as the doors open and close and what I think is the Chiltern Court clock. The Chesham train footage has (as far as I am aware) never been seen before.
