"Rickmansworth, an ancient township of narrow streets, lies most picturesquely in its valley, where a sharp tongue of Hertfordshire thrusts itself down between Middlesex and Bucks," according to the Metroland brochure produced by the Metropolitan Railway in 1932 to promote the idea of moving out of London to rural areas served by the company's trains. In this episode we look at how the Met came to be extended to Rickmansworth and beyond, and the suburbanisation that it caused. We also discover the long-closed railway to Rickmansworth Church Street station, which used tube trains neither owned nor operated by the Underground.
