The boiler is about 13 feet long and 4 feet in diameter, and has a large U-shaped return flue. The cylinders are mounted vertically at the rear, and the piston rods are guided by Watt’s parallel motion instead of the usual cross heads and slide bars. The engine has no frame, the axle bearings being bolted to brackets riveted to the under side of the boiler. Only the front and middle axle bearings are fitted with springs. In the course of its working career, the _Samson_ traveled considerably. In addition to having been brought across the Atlantic, the old locomotive was brought to Chicago in 1883 for display at the Exposition of Railway Appliances (figure 54). There it was accompanied by George Davidson, long its engineer and said to have come with it to Nova Scotia from England. [Illustration: Figure 55.—_Samson_, with an original passenger car of 1840, at the Fair of the Iron Horse, September 30, 1927.] Ten years later, in 1893, it was again brought to Chicago, this time to be exhibited at the World’s Columbian Exposition. At the conclusion of the exposition the _Samson_, and the _Albion_ that had accompanied it, were taken by the Baltimore and Ohio Railroad Co. to Baltimore for preservation there. The B & O later included the _Samson_ (and also the _Albion_) in the exhibition of historic locomotives at the Fair of the Iron Horse in 1927 (figure 55). In June 1928, when the two old locomotives were given by the B & O to the Province of Nova Scotia, the _Samson_ returned to the land of its youth, only to be placed in storage in Halifax. Later, however, it was given to the town of New Glasgow, through which it had run almost daily in its early days, and it is now housed in a small building especially constructed for it at the town’s railroad station. The Final Decade In 1839 the Philadelphia locomotive building firm of Eastwick and Harrison constructed to the order of Moncure Robinson for the Philadelphia and Reading Rail Road Co. a noteworthy anthracite-burning locomotive, named the _Gowan and Marx_ after an English banking firm. This engine during trials on February 20, 1840, turned in what was for the time an outstanding performance. It hauled from Reading to the inclined plane on the Columbia and Philadelphia Rail Road, located several miles from Vine and Broad Streets in Philadelphia, 101 cars of freight, a load of 423 long tons (2,240 pounds). The total weight of this load was 947,520 pounds not including the weight of the engine itself and its tender. The engine, in running order, weighed 24,660 pounds. The story of this remarkable feat is told by Joseph Harrison, Jr., in his book, “The Locomotive Engine, and Philadelphia’s Share in Its Early Improvements.”
