A roundhouse is a type of train station designed primarily for the servicing and storage of locomotives. It features a circular or semicircular layout, allowing multiple tracks to radiate from a central turntable. This design enables trains to be easily maneuvered in and out of the facility, making it efficient for maintenance and repairs. Typically found near rail yards, roundhouses were essential during the steam locomotive era, as they provided shelter from the elements and space for workers to perform necessary upkeep. Today, many roundhouses have been preserved as historical sites or repurposed for modern uses, reflecting the evolution of rail transport.
