The engine seen here at the Railroad Museum of Pennsylvania is the SECOND of two Altoona Shops built "John Stevens" replicas. This particular operable engine was built by the Pennsylvania Railroad in 1939, a tribute to the railroad's own heritage as Pennsy's very own roots stem from the Col. John Stevens's railroad - the New Jersey Rail Road and Transportation Company which utilized the actual "John Stevens" prototype steam engine built by Col. John Stevens himself in 1825 on a circular track at his estate at Castle Point, Hoboken, NJ. The state of New Jersey granted America's first railroad charter to Col. John Stevens of Hoboken, to run between New Brunswick and Trenton, NJ. Because of funding difficulties, however, it was never built. Col. John Stevens sons went on to operate the Camden and Amboy Railroad (A PRR predecessor) in the following years utilizing Robert Stephenson's "John Bull".
