Featuring transport historian and architecture enthusiast Tim Dunn, this is a 10 part series around the construction of many station buildings across the UK and Europe. It premiered in the UK last April. Series One, Episode One: Down Street Monday, 7.35pm Tim Dunn goes deep underground in central London to explore a disused tube station that played a crucial tactical role during the Second World War. Down Street station in Mayfair opened in 1907 but closed after just 25 years because of low passenger numbers. However, when war broke out, it became the secret base of the executive committee who coordinated all rail travel across Britain. The station now is very much as they left it and Tim gets a guided tour of the former platforms – as the Piccadilly line rumbles past.
