900 mm gauge railways

900 mm (2 ft 11 ⁷⁄₁₆ in) narrow-gauge railways are generally found in Europe. This gauge is mostly used for light urban rail networks, industrial and agricultural railways.

Norway	Used by the Germans up to 1945, called Feldbahn (field railway), for industrial plants or other temporary uses. In Norway during the WW II the Germans built a 15 km railway between the harbour at Årdalstangen and the industrial plant of Øvre Årda. It closed in 1959, by then used only at the iron works. One steam locomotive was lost into the sea, but was found by divers around 1990 and is restored and exhibited at Aardalstangen.

In Sweden there has been an extensive network of railways with 891 mm (2 ft 11 ³⁄₃₂ in) gauge, Swedish three foot gauge railways. Some of them remain. This is so close to 900 mm (2 ft 11 ⁷⁄₁₆ in) that they are more or less compatible, and some sales of rolling stock between the gauges have taken place.
