Since the 1893 unveiling of the replica of the train at Chicago, it has been displayed at the Louisiana Purchase Exposition at St. Louis in 1904, the Fair of the Iron Horse (figure 27), the Chicago World’s Fair in 1933 and 1934, the New York World’s Fair in 1939 and 1940, the Chicago Railroad Fair in 1948 and 1949, and on many other occasions. For years the train was exhibited on a balcony within New York City’s Grand Central Terminal, but since 1935 it has been on loan from the New York Central System to the Henry Ford Museum at Dearborn. An exquisitely made nonoperable model of the _De Witt Clinton_, its tender, and three cars, together about 3 feet long (figure 28), was made in 1932 by Peyton L. Morgan of Lynchburg, Va., and has been since 1935 in the collection of the National Museum (USNM 310961).

Built in England in 1831 by Robert Stephenson & Co. of Newcastle-upon-Tyne, it was officially placed in service on November 12, 1831, at Bordentown, N. J., on the lines of the Camden and Amboy Rail Road and Transportation Co., now a part of the Pennsylvania Railroad Co. In regular service until 1865, the locomotive was given by the Pennsylvania Railroad Co. to the National Museum in 1885 (USNM 180001). It should not be confused with another Stephenson-built locomotive of the same name, built for the Mohawk and Hudson Rail Road Co. at the same time but no longer in existence. The Camden and Amboy’s _John Bull_, its first locomotive, was ordered from Stephenson by Robert L. Stevens of New Jersey, son of the railroad pioneer Col. John Stevens, and president of the company, who had gone to England in October 1830 for this purpose, as well as to purchase iron rails of his design for the track of the new railroad. The locomotive was completed early in the summer of 1831 and was shipped from Liverpool on the ship _Allegheny_, which sailed for Philadelphia on July 14. It had been disassembled for shipping, as were most of the early locomotives, and it is interesting to note that the freight charge was only £19, or a little under $100. The total cost of the locomotive, incidentally, was £784 7s. 0d., or a little under $4,000.
