Narrow Gauge Mine Car are railways with a track width of less than 1,435 millimeters, which is the standard gauge. Most narrow-gauge railways have a track width between 600 millimeters and 1,067 millimeters.
In the 19th century, logging operations in mountainous areas typically used Narrow Gauge Mine Car to transport timber from factories to markets. Important sugarcane railways are still in operation in Cuba, Fiji, Java, the Philippines, and Queensland, and narrow-gauge railway equipment is still widely used in tunnel construction. Many narrow-gauge railways are part of industrial enterprises, primarily serving as industrial railways rather than general transportation tools. Common uses of these industrial narrow-gauge railways include mining, logging, construction, tunneling, quarrying, and transporting agricultural products.
Due to the fact that Narrow Gauge Mine Car are typically built with tighter curves, smaller structural standards, and lighter tracks, their construction, equipment, and operating costs are usually lower than those of standard or broad-gauge railways, especially in mountainous or difficult terrain. Low-cost narrow-gauge railways are often used in mountainous areas, where engineering savings can be quite substantial. Low-cost narrow-gauge railways are commonly employed to serve industries and sparsely populated communities, where the traffic potential does not justify the cost of building standard or broad-gauge lines. Narrow Gauge Mine Car have specialized uses in mines and other environments that require small structural standards to accommodate small loading standards.
