The term "30-inch railways" typically refers to narrow-gauge railways that have a track gauge of 30 inches (approximately 76.2 cm). Narrow-gauge railways are often used in mountainous areas or for industrial purposes where tighter curves and steeper gradients can be accommodated compared to standard gauge railways.
