Great British Railway Journeys - Season 9 Episode 2

Letchworth Garden City to Herne Hill Michael joins a garden party where a fourth-generation citizen of Letchworth introduces him to the city's community spirit. Heading into the capital, Michael discovers a favoured haunt of King Edward VII and samples the monarch's favourite tipple, the King's Ginger, invented to keep him warm in his horseless carriage. Improvements to the London Underground in the early 20th century gave us a network of electric railways, which shaped our modern capital. Inside London's newest rail tunnel, Michael meets engineer Jonathan Cooper to discover more about current improvements to London's oldest deep-level tube line, the Northern line, which is being extended.
