Narrow gauge refers to a railway track where the distance between the rails is narrower than the standard gauge of 143.5 centimeters. Narrow gauge tracks are often used in regions where space is limited, such as in mountainous areas, or for specialized purposes like light rail systems. These tracks allow trains to navigate tighter curves and steeper slopes more easily, making them suitable for certain types of terrain. While narrow gauge trains are typically smaller and carry fewer passengers or lighter loads, they are more cost-effective to build and maintain in challenging locations.
