An 0-4-0ST locomotive is a small saddle-tank steam locomotive with four coupled driving wheels and no leading or trailing axles. The water tank sits on top of the boiler (saddle tank) instead of being carried in a tender. Compact, simple, and powerful at low speeds, these locomotives were commonly used for shunting, quarry work, industrial railways, and narrow-gauge lines, where tight curves and short track layouts required a small but strong engine.
