This train paper model is the JGR Class 7100 Steam Locomotive, designed by Ruben. The JGR Class 7100 was a Japanese steam locomotive was first used in Hokkaido, upon the establishment of the government-sponsored Horonai Railway in 1880. The locomotives were imported from the United States.
The locomotives were produced by the American company H. K. Porter, Inc. Two were purchased in 1880 (Nos. 368, 369), two more in 1882 (Nos. 487, 488), one in 1884 (No. 643), one in 1885 (No. 672), and two more in 1889 (Nos. 1009, 1010), for a total of eight. Six of the locomotives were named after major historical or literary figures in 1889, at the suggestion of the Japanese Consul of New York City, Takagi Saburō, who found appeal in the similar practice seen in the United States at the time. Thus, the six became known as Yoshitsune, Benkei, Hirafu, Mitsukuni, Nobuhiro, and Shizuka.
Service began between Sapporo and Temiya on 28 November 1880, via Yoshitsune and Benkei. The following year, on 30 August 1881, Emperor Meiji rode the line, called Kaitakushi-gō. Pulling nine cars in poor weather, the train arrived late, but this was said to be acceptable; it is not clear which locomotive was used. The line was extended in 1882 to connect Sapporo with Horonai, and Hirafu and Mitsukuni were obtained. Nobuhiro and Shizuka were purchased soon afterwards, and in 1887 a Baldwin Locomotive Works 1-C tender was also purchased, which was given the class number 7170. When the last of the H.K. Porter locomotives were purchased, the trains' ordinals were rearranged to group the Porters together.
The railway company changed ownership in 1889, the Hironai Railway being sold to the Hokkaidō Colliery and Railway Company. Under this company, the locomotives were rebuilt, their smokestacks, cowcatchers, and other features changed or removed. Ten years later, the seventh train was purchased by the Hokkaidō government railway and repaired; but it barely saw service, and was only used to aid in construction and to plow snow.
The tender locomotive's driving wheel was 914 mm (3 ft), and the axles 2-6-0. It used the standard Stephenson gauge. The tender had two two-axled bogies, with the unofficial names written in large kanji. The lettering style is said to emulate the handwriting style of either Settlement Envoy Kuroda Nagamasa or Secretary Sannai Rokusaburō.
The locomotives were outfitted with cow catchers, smokestacks, bell, oil lamp headlights, and a wooden driver's compartment in the first boiler compartment, all in emulation of American styles. Similarly, the second boiler compartment contained the boiler, sandbox, and a steam-dome above the furnace. The two purchased in 1880 used Westinghouse air brakes, which was quite new and advanced at the time; it allowed the brakes to be applied to all cars simultaneously.
