The model (figure 75) is powered by eight electric motors, as is the full sized original, one for each axle, but because of space limitations and power requirements the model’s drive is through gears rather than direct. The model operates on 12-volt direct current. Its length is 43 inches and its gauge is 3½ inches. The New York Central System purchased 10 class T-3A locomotives in late 1926 at a cost of $100,000 each. These supplemented an earlier group of 10 T-1’s and 16 T-2’s built for the New York Central from 1913 to 1917 at the Erie, Pa., plant of the General Electric Co. Of this total of 36 locomotives only one, _No. 270_ (formerly _No. 1170_), had been stricken from the records as of December 1954. The remaining 35 still perform routine passenger service between New York and Harmon, and New York and North White Plains. The numbers in the group now run from 247 to 282 (formerly 1147 to 1182), with the exception of the scrapped _No. 270_. [Illustration: Figure 75.—Operable model of General Electric locomotive, 1926.] With an operating weight of 292,600 pounds, the locomotives of the T-3A class develop 1,908 horsepower continuously, with a tractive force of 12,750 pounds, and they can develop 2,488 horsepower for 1 hour, with a tractive force of 18,440 pounds. The maximum speed of a T-3A is 75 miles an hour. These locomotives operate on 660-volt direct current, usually obtained from a third rail. The pantographs are used only when crossing certain complicated crossover switches. Each of the eight axles is driven by its individual gearless motor. The overall wheelbase is 46 feet, 5 inches, the overall length 56 feet, 10 inches. B & O Hudson-Type Locomotive Lord Baltimore, 1935 During the winter of 1936-1937, The Baltimore and Ohio Railroad Co. conducted in conjunction with the magazine “The Model Craftsman” a contest among model builders for the construction of a model of the railroad’s Washington-to-Jersey City lightweight, streamlined train, the “Royal Blue,” first placed in operation on June 24, 1935. [Illustration: Figure 76.—Model of B & O Hudson-type locomotive _Lord Baltimore_, 1935.] The contest, with a first prize of $500, was won by Fletcher G. Speed of New Rochelle, N. Y., and his prize-winning train (figure 76) was presented by the Baltimore and Ohio in 1937 to the National Museum (USNM 311191). The train consists of the Hudson-type, or 4-6-4, steam locomotive _Lord Baltimore_ and tender, together 2 feet long, plus five cars. Beautiful in workmanship, and powered with a small electric motor, the model is built to a scale of ¼ inch to the foot.
