The Chichibu Railway Class DeKi 200(秩父鉄道デキ200形) is a Bo-Bo wheel arrangement DC electric locomotive type operated by the private railway operator Chichibu Railway in Saitama Prefecture, Japan, since 1963. [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 2014, one (DeKi 201) out of the original three locomotives is in operation. [2] The locomotive is painted in a brown livery with gold lining, [2] and is primarily used as an assisting locomotive on steam-hauled SL Paleo Express services and on empty stock movements. [1]

History

Three locomotives, DeKi 201 to 203, were built in 1963 to provide additional capacity hauling limestone trains on the Chichibu Main Line. [1] The design was broadly based on the earlier Class DeKi 100 locomotives, with four 230 kW traction motors instead of the earlier 200 kW motors. [1]

In July 2000, two Class DeKi 200 locomotives, DeKi 202 and 203 were sold to the Sangi Railway in Mie Prefecture, where they were used to haul trains of landfill during construction of the Chūbu Centrair International Airport. [1] The lack of ATS equipment meant that the locomotives could not run on the main line, and were finally withdrawn in March 2011. [1]

The Hokusei Line was transferred from Kintetsu ownership in 2003, when Kintetsu abandoned the line. Whereas the Sangi Line has a track gauge of 1,067 mm, the Hokusei Line is one of only a few 762 mm narrow gauge lines remaining in the country.
