This is a side view of John Bull, one of the oldest steam locomotives in the world. It was built in England in 1831 as a 0-4-0 by Stephenson, and was shipped to the Camden and Amboy Railroad, the first line in New Jersey. It arrived in America disassembled with no instructions, but the railroad's master mechanic Isaac Dripps was able to build the complete engine. He would later on improve the design, as the 0-4-0 kept derailing on rough track, so Isaac Dripps disconnected the driving axles and added an extra front axle, creating a 4-2-0 with a cowcatcher. John Bull served the Camden and Amboy until 1866, whereupon it was used only for publicity. It was bought by the Smithsonian in 1981, and is now on display in the National Museum of American History outside the transportation gallery
