Thousands of locomotive roundhouses, built for steam locomotive maintenance, were once found across the American landscape. Now, only a few remain.

Check out the story, coming to you from the largest remaining roundhouse in North America, the Bob Julian Roundhouse in Spencer, NC. #nctrans #nctransportationmuseum #spencershops #steam #locomotives #roundhouse
