The Chichibu Railway Class DeKi 300(秩父鉄道デキ300形) is a Bo-Bo wheel arrangement DC electric locomotive type operated by the private railway operator Chichibu Railway in Saitama Prefecture, Japan, primarily on freight services, since 1967. [1]

B-B and Bo-Bo are the Association of American Railroads (AAR) and British classifications of wheel arrangement for railway locomotives with four axles in two individual bogies. They are equivalent to the B′B′ and Bo′Bo′ classifications in the UIC system. The arrangement of two, two-axled, bogies is a common wheel arrangement for modern electric and diesel locomotives.

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.

As of 1 April 2016, all of the original three locomotives are in operation. [2]

History

Three locomotives, DeKi 301 to 303, were built in 1967. [1] The design was broadly based on the earlier Class DeKi 200 locomotives, with four 230 kW traction motors, although the non-standard bogie design of the DeKi 200 was not used. [1] The cab window sun visors of the DeKi 200 were also discontinued on the DeKi 300. [1]
