Great British Railway Journeys (2010)
S9E2 Letchworth Garden City to Herne Hill
Michael attends a garden gathering where a long-time resident of Letchworth shares insights about the town's vibrant community. Venturing into London, he visits a popular spot once frequented by King Edward VII and tries the King's Ginger, a warming drink crafted for the monarch during his carriage rides. The early 20th century brought significant upgrades to the London Underground, creating an extensive electric railway system that transformed the city. In a newly constructed rail tunnel, Michael meets engineer Jonathan Cooper, who enlightens him about the ongoing expansion of the historic Northern line.
