The was an electric multiple unit (EMU) train type operated by the private railway operator Choshi Electric Railway in Chiba Prefecture, Japan, between 1939 and 1999.[1]
DeHa 101 was built in February 1939 by (present-day Toyokouki) as "BoDeHa 101" (with "Bo" designating it as a bogie car) with a wood and steel body mounted on Amemiya plate-frame bogies donated from former 1926-vintage gauge DeHa 103 which previously operated on what is now the Tōbu Kinugawa Line and was withdrawn in July 1932.[1] [2]
On 9 May 1939, shortly after BoDeHa 101 entered service, Princess Shigeko (daughter of Emperor Hirohito) rode on the train from to Tōdaimae (present-day Inuboh Station) and back on a Gakushūin school outing.[1]
BoDeHa 101 was renumbered DeHa 101 from 29 May 1950, and in December 1952, it was rebuilt by Nippon Tetsudō Jidōsha Kōgyō with a new steel and wood-frame body with air-operated sliding doors.[1]
The original trolley pole current collector was replaced by a bow collector in 1966.[2]
Following the introduction of DeHa 501 in the 1970s, DeHa 101 was used less frequently, and was often used as a non-powered car sandwiched between DeHa 301 and DeHa 501.[3] It was also sometimes used to haul freight services in place of the electric locomotive DeKi 3.[1]
In 1985, DeHa 101 was used extensively in filming for the NHK TV drama series, which was shot on the Choshi Electric Railway. Budget limitations meant that the bow collector could not be replaced with its original trolley pole current collector, nor could the car be repainted into the period style livery of all-over brown.[1]
In later years, the car was used as a storeroom at Kasagami-Kurohae Station, and was officially withdrawn on 31 March 1999. It remained dumped at Kasagami-Kurohae Station until it was cut up on 27 September 2009. The Amemiya plate-frame bogies were preserved, however, with the Tokawa-end bogie donated to the Tobu Museum in Tokyo, and the Chōshi-end bogie preserved at Ōgo Depot on the Jōmō Electric Railway in Gunma Prefecture.[1]
