The locomotive, which had been shipped up the Hudson River to Albany during the last week of June with David Matthew in charge, weighed a little over 6,750 pounds, was 11½ feet long, and was mounted on four 54-inch wheels, all of which were drivers. The two cylinders, at the rear of the locomotive and connected to the axle of the front wheels, had a bore of 5½ inches and a stroke of 16 inches. The boiler was tubular, with copper tubes about 2½ inches in diameter and 6 feet long. The top speed when pulling a load of about 8 tons was said to have been about 30 miles an hour. [Illustration: Figure 24.—Wheel, said to be from original _De Witt Clinton_, in National Museum.] The _De Witt Clinton_ was never completely satisfactory, and after infrequent use in 1831 and 1832 it was disassembled and disposed of piece by piece. Some of the parts were listed as sold on April 20, 1835, others on September 13 and October 29, 1836. A total of $485 was realized from the various sales. In 1891, a wheel said to have been one of the wheels of the original _De Witt Clinton_, was deposited in the National Museum (USNM 180947) by William Buchanan, at that time superintendent of motive power of the New York Central and Hudson River Railroad Co. The all-metal wheel (figure 24) contains 14 round, 1-inch-diameter spokes staggered around the hub, and is 52½ inches in diameter. The flanged metal tire is missing from the rim, which is 4⅛ inches wide, but its presence would undoubtedly bring the overall diameter of the wheel up to 54 inches.

The replica, constructed from the original plans of 1831, was made at the railroad’s shops at West Albany, N. Y. During the past 60 years the replica has undergone a number of repair operations, but it remains authentic. It has been exhibited on many occasions (figure 26).
