An affiliate of the Smithsonian Institution, the museum houses the Western Hemisphere's oldest and most extensive collection of vintage railroad equipment. Visitors to the 40-acre complex -- located in Baltimore at the site of the country's first mile of commercial railroad track -- can look at trains big and small, from historic locomotives bearing a resemblance to "The Polar Express" steam engine to a detailed HO scale layout (in which 3.5 millimeters correspond to a foot in actual size).
