The wheel at Newport is built up of parts, and consists of a large round hub, 12 round 1¼-inch-diameter spokes, a rim approximately 46 inches in diameter and 4½ inches wide, and a flanged tire 4¾ inches wide and about 1 inch thick, the flange of which is 2 inches wide on its outside face. The wheel, therefore, has a diameter of about 48 inches. The spokes are staggered in the hub and appear to be fastened to it by threaded nuts. Four keyways are cut into the hole in the hub. The complete history and exact origin of this wheel, given to the Redwood Library in January 1863 by Isaac P. Hazard of Newport, will probably remain a mystery. As with other early locomotives, a full sized operable replica of the _Best Friend_ has been built. The Southern Railway System, which now includes the old South-Carolina Canal and Rail-Road, in 1928 constructed a faithful replica of the locomotive at its Birmingham, Ala., shops, and in the same year reproduced the original tender and several cars at its shops at Hayne, S. C. (figure 21). A new boiler was installed on the replica in 1948. Among the various fairs at which it has been exhibited are those held at New York in 1939 and 1940 and in Chicago in 1948 and 1949. At present it is to be seen in the depot of the Chattanooga Station Co. at Chattanooga, Tenn. A small, nonoperable model of the _Best Friend_, about 2 feet long (figure 22), with tender and two cars, was made in the late 1880’s by D. Ballauf, well known model maker of Washington, D. C. It was first exhibited at the Cincinnati Centennial Exposition in 1888, after which it was placed on exhibition in the National Museum (USNM 180244). Of the _West Point_, the second locomotive built by the West Point Foundry Association, and the second bought by the South-Carolina Canal and Rail-Road Co., no relics or replicas are known to exist. A satisfactory locomotive, it arrived at Charleston on the ship _Lafayette_ on February 28, 1831. Its final disposition is no longer known.

Its first public demonstration was an excursion trip on August 9, 1831, on a 12-mile stretch of railway between Albany and Schenectady. The distance was covered in less than one hour. Another notable demonstration, attended by many public officials, took place on September 24 of the same year.
