### Minimum and ridable miniature railways

For ridable miniature railways and minimum-gauge railways, the gauges are overlapping. There are also some extreme narrow-gauge railways listed. See: Distinction between a ridable miniature railway and a minimum-gauge railway for clarification.
Model railway gauges are covered in rail transport modelling scales.

### Standard gauge

Standard gauge is 4 ft 8+1⁄2 in (1,435 mm) gauge. It is the most widely-used gauge: about 60% of the world's railway mileage is standard gauge.
Several railways use gauges very close to standard gauge, including:
