Two Kings

The film begins at London's King's Cross station, highlighting its recent remodeling and the operation from the Rail Operating Centre in York. Viewers follow an eight-car EMU as it travels along the down fast line, reaching speeds of 100 mph while navigating the outskirts of North London.

As the journey progresses, the film covers significant locations, such as the Welwyn viaduct bottleneck and the specially-built single track flyover at Hitchin, which leads to the Cambridge line. The documentary features non-stop travel from King's Cross to the University City of Cambridge, with stops at Cambridge North, Warerbeach, Ely, Littleport, Downham Market, and Watlington.

The scenic Fen line is a highlight, showcasing both double and single track sections, ultimately terminating in the historic market town of King's Lynn. This film offers a detailed and informative look at railway travel, making it a compelling addition to any transportation-focused collection.
