"Apparently inspired by both the Clayton Tunnel collision of 1961 and the Dickens' first-hand experience of Staplehurst rail crash four years later, The Signalman is without question one of the strongest films in the [BBC] Ghost Story series and remains today of the finest of all televisual tales of the supernatural. The story was adapted by Andrew Davies – who was later to pen such luminary television works as A Very Peculiar Practice, House of Cards and a number of adaptations of literary classics, including two Dickens novels – and benefits greatly from being faithful to the source story, right down to the period formality of the dialogue." - Slarek, Cine Outsider
