John Bull (locomotive)

The original John Bull in the first-floor lobby of the Smithsonian's National Museum of American History in Washington, D.C. Robert Stephenson and Company built it in England in 1831 for New Jersey's Camden and Amboy Railroad, as a 0-4-0 that was later rebuilt with a leading truck, the reason it is usually labeled a 4-2-0. On September 15, 1981, 150 years to the day after it first raised steam, it ran again beside the C&O Canal, and the Smithsonian still calls it the oldest locomotive capable of operation. It has stayed a static exhibit since that run.
