List of 2 ft 3 in gauge railways

In railway terminology, track gauge indicates the distance between the inside edges of the running rails.

In Britain, standard gauge is used for all main line routes and the majority of urban light rail.

Narrow gauge railways were constructed mainly where there was a need for tighter curves, smaller structure gauges, and lighter rails, as they could be less costly to build, equip and operate than standard gauge railways (particularly in mountainous or difficult terrain).

This list, whilst incomplete, details all railways that are believed to have used 2 ft 3 in (686 mm) gauge at some point during their existence.

A number of 700 mm (2 ft 3+9⁄16 in) gauge railways existed in Latvia, the Netherlands and Romania and several there were Cuban sugar cane railways.
