Narrow-gauge railways in Bosnia and Herzegovina

With the demise of a connecting network all the other remaining narrow-gauge lines were then at risk and restricted to local traffic.

Built as a group of four main forest railways of the "Bosnische Forstindustrie AG Otto Steinbeis".

A small part of the track is still in service as a heritage railway rebuilt between 1999 and 2003, Šargan Eight.

There were numerous private industrial and mostly forestry narrow-gauge railroads in operation throughout the late 19th and most of 20th century, with varying construction and deconstruction dates.

Bosanska Mezgraja–Bijeljina–Ugljevik; An isolated 760 mm (2 ft 5+15⁄16 in) gauge railway Split–Sinj (completed in Croatia); 40 km, 1903–62.

A planned extension via Aržano to Bugojno (and further on existing tracks to Sarajevo) never materialized because of World War I and the line remained isolated from the Bosnian 760 mm (2 ft 5+15⁄16 in) network.
