Beattie Well Tank locomotive

The Beattie Well Tank locomotive is a type of steam engine designed to carry water internally within the boiler's structure, rather than in separate side tanks. Its distinctive feature is a well or hollow area inside the boiler, which contains the water. This design lowers the locomotive's overall center of gravity, enhancing stability and making it suitable for shunting or short-distance work, especially in industrial or narrow-gauge settings. The engine's compact form allows for good maneuverability in confined spaces while maintaining the necessary power for tasks like hauling light trains or moving rail cars within yards.
