Definition
A tank locomotive is essentially the same as a tank engine: a steam locomotive that carries its own water and fuel supply on the engine frame itself, instead of in a separate tender car. This design results in a more compact and agile locomotive. Imagine a steam train without needing an extra car attached for water. Tank locomotives were especially useful in urban areas, industrial settings, and for short-distance routes where frequent turns and quick stops were necessary. They are a testament to clever engineering. 🚂 They could swiftly navigate tighter spaces.
