The beginning of a series of slide shows documenting the B&O Old Main Line in Maryland, from the roundhouse to Harper's Ferry. I have 1000's of pics and lots of video, and I'm getting more all the time. Please subscribe, rate, and comment. I will continue to put up more asap. "In the late 19th century, an overzealous publicity agent developed a trade show exhibit for a major American railroad headquartered in Baltimore, Maryland. This exhibit survived the railroad that sponsored it and grew to become a "national treasure" of railroad artifacts. Today, it comprises the collection of the Baltimore & Ohio Railroad Museum, the oldest, most comprehensive American railroad collection in the world. Located among Baltimore City's historic southwest neighborhoods, at the original site of the historic Mt. Clare Shops, the B&O Railroad Museum is recognized universally as the birthplace of American railroading. It was here within the Museum's 40-acre campus that Baltimore businessmen, surveyors, and engineers set about building the B&O Railroad in 1829, laying the first commercial long-distance track, building the first passenger station, and inventing America's unique railroad. Railroad work has been conducted at Mt. Clare for over 130 years. And it continues today."
