roundhouse
A roundhouse is a structure used primarily for storing and servicing locomotives and railway cars. Its circular design allows multiple tracks to converge in a central area, making it easy to turn trains around. Roundhouses often feature large doors that open to the tracks, facilitating the movement of trains in and out.
Typically found in railway yards, roundhouses were essential during the steam engine era, as they provided space for maintenance and repairs. Many roundhouses are now preserved as historical sites, showcasing the evolution of railway technology and the importance of steam locomotives in transportation history.
