The Duffield Bank Railway was built by Sir Arthur Percival Heywood in the grounds of his house on the hillside overlooking Duffield, Derbyshire in 1874. The Ordnance Survey map for 1880 does not show the railway itself, it does show two tunnels and two signal posts.
Heywood added some stations, as well as a sleeping car with toilet and a diner with its own cooking compartment.
