The 7 Ton Decauville is a small 0-3-0 narrow-gauge steam locomotive built for light industrial and temporary railway work. Compact and lightweight, it was designed for easy transport and operation on lightly laid track in quarries, mines, and construction sites. Its simple construction and reliable traction made it well-suited for short-distance hauling in confined environments.
