Railway Turntable - Roundhouse

Roundhouse

In engine maintenance facilities, a turntable was usually surrounded, in part or in whole, by a roundhouse. It was more common for the roundhouse to only cover a portion of the land around a turntable but fully circular roundhouses exist, such as these preserved roundhouses:

• The roundhouse that serves as the basis for the Baltimore and Ohio Railroad Museum in Baltimore, MD
• The Roundhouse in London, England, now an arts centre.
