The Prince William Railway Company (German: Prinz-Wilhelm-Eisenbahn-Gesellschaft, PWE) was the first horse-drawn railway in Germany. It was originally founded as the Deil Valley Railway Company (Deilthaler Eisenbahn Aktiengesellschaft) in 1828 and renamed in 1831. It built a 820 mm (2 ft 8 ⁹⁄₃₂ in) narrow gauge line that ran for a Prussian mile (7,532 metres) along the Deilbach valley from a point near Kupferdreh Old Station in Hinsbeck, a suburb of Kupferdreh (now part of Essen), to Nierenhof near Langenberg (now part of Velbert).
