The Walt Disney World Railroad is a 3-foot (914 mm) narrow-gauge American heritage railroad and attraction that encircles most of the Magic Kingdom theme park of Walt Disney World in Bay Lake, Florida. Constructed by WED Enterprises, it has three train stations along 1.5 miles (2.4 km) of track, and four historic steam locomotives, originally built by Baldwin Locomotive Works. On a typical day, two or three locomotives will complete round trips in 20 minutes on the main line. The railroad's development was led by Roger E. Broggie. The attraction's locomotives were acquired from the Ferrocarriles Unidos de Yucatán, a narrow-gauge railroad system in Mexico, and altered to resemble locomotives built in the 1880s. The passenger cars were built from scratch. The railroad opened to the public for the first time on the theme park's opening day, October 1, 1971. Since then, it has become one of the world's most popular steam-powered railroads, with about 3.7 million passengers each year. (Full article...)
