The EH10 class of electric locomotives were Bo′Bo′+Bo′Bo′ wheel arrangement two-unit DC freight locomotives operated by Japanese National Railways (JNR) in Japan from 1954 until 1982. [1] [2]

In rail transport, a wheel arrangement or wheel configuration is a system of classifying the way in which wheels are distributed under a locomotive. Several notations exist to describe the wheel assemblies of a locomotive by type, position, and connections, with the adopted notations varying by country. Within a given country, different notations may also be employed for different kinds of locomotives, such as steam, electric, and diesel powered.

Direct current Unidirectional flow of electric charge

Direct current (DC) is the unidirectional flow of electric charge. A battery is a good example of a DC power supply. Direct current may flow in a conductor such as a wire, but can also flow through semiconductors, insulators, or even through a vacuum as in electron or ion beams. The electric current flows in a constant direction, distinguishing it from alternating current (AC). A term formerly used for this type of current was galvanic current.

Japanese National Railways, abbreviated Kokutetsu (国鉄) or "JNR", was the business entity that operated Japan's national railway network from 1949 to 1987.

The exterior was designed by industrial designer Masao Hagiwara.[ citation needed ]

The EH10 was used for 1,200 tonne freight trains on the Tōkaidō Main Line between Tokyo (Shiodome) and Osaka (Umeda).

Tōkaidō Main Line railway line in Japan

The Tōkaidō Main Line is a major Japanese railway line of the Japan Railways Group network, connecting Tokyo and Kōbe stations. It is 515.4 km (320.3 mi) long, not counting its many freight feeder lines around the major cities. The high-speed Tōkaidō Shinkansen largely parallels the line.

Tokyo Metropolis in Kantō

Tokyo, officially Tokyo Metropolis, one of the 47 prefectures of Japan, has served as the Japanese capital since 1869. As of 2018, the Greater Tokyo Area ranked as the most populous metropolitan area in the world. The urban area houses the seat of the Emperor of Japan, of the Japanese government and of the National Diet. Tokyo forms part of the Kantō region on the southeastern side of Japan's main island, Honshu, and includes the Izu Islands and Ogasawara Islands. Tokyo was formerly named Edo when Shōgun Tokugawa Ieyasu made the city his headquarters in 1603. It became the capital after Emperor Meiji moved his seat to the city from Kyoto in 1868; at that time Edo was renamed Tokyo. Tokyo Metropolis formed in 1943 from the merger of the former Tokyo Prefecture and the city of Tokyo. Tokyo is often referred to as a city but is officially known and governed as a "metropolitan prefecture", which differs from and combines elements of a city and a prefecture, a characteristic unique to Tokyo.

Osaka Designated city in Kansai, Japan

Osaka is a designated city in the Kansai region of Japan. It is the capital city of Osaka Prefecture and the largest component of the Keihanshin Metropolitan Area, the second largest metropolitan area in Japan and among the largest in the world with over 19 million inhabitants. Osaka will host Expo 2025. The current mayor of Osaka is Ichiro Matsui.

One example, EH10 61, is preserved at Higashi-Awaji Minami Park in Osaka.

JNR Class DD51 Japanese diesel-hydraulic locomotive

The Class DD51 (DD51形) is a B-2-B wheel arrangement diesel-hydraulic locomotive type operated in Japan since 1962. 649 locomotives were built between 1962 and 1978 by Kawasaki Sharyo, Hitachi, and Mitsubishi. The class was designed for mainline passenger and freight use with more power than the D51 and a higher maximum speed than the C62 steam locomotive classes. This was achieved by installing two 1,100 hp engines in an 18 metre long centre-cab design, unusual for mainline operation. The V12 DML61 engines were developed from the 6-cylinder inline DMF31 engines used in the Class DD13 locomotives. As of 1 April 2016, 29 locomotives remained in operation.
