The EP10 (ЭП10) is a type of dual voltage six axle electric locomotive built for RŽD by NEVZ in association with Adtranz/Bombardier for passenger use. The design was considered costly, and only 12 units were acquired. ==History== Prior to the collapse of the Eastern Bloc and the breakup of the Soviet Union, passenger locomotives used in Russia had been sourced from Czechoslovakia.〔 Afterwards these sources were considered too expensive and the Russian state sought to develop indigenous production of passenger rolling stock.〔 Resolution number 1400 (23 November 1996) of the Russian Federation ''"Разработка и производство пассажирского подвижного состава нового поколения на предприятиях России"'' (design and manufacture of new generation passenger rolling stock) allocated funding from the state to develop and manufacture passenger rail vehicles, including the development of a type ЭП10, specified as a six axle, dual voltage locomotive, of 6.6MW power with asynchronous traction motors and regenerative and rheostatic braking, and an operating speed of 120 to 160 km/h. The machine was to be designed by АООТ "ВЭлНИИ" (VELNII) and АООТ НПО "НЭВЗ" (NEVZ), in association with a foreign company, and manufactured by VELNII with an expected schedule of prototype delivery in 1997 and series production in 1999. The prototype was unveiled at Novocherkassk Electric Locomotive Plant (NEVZ) on 20 November 1998. Initially it was expected that DC and AC only versions ЭП2 (EP2) and ЭП3 (EP3) would be developed based on the asynchronous traction technology introduced in the EP10.〔Sources: * * *〕 Certification testing was complete in February 2005. An order for 11 locomotives was placed in 2005 with Transmashholding and Bombardier Transportation; locomotives No.2 & 3 began production in 2005. The order was valued at 450 million rubles; RZD initially refused to place an order for the type, citing the high unit price. In 2006 RZD chief engineer Valentin Gapanovich stated that only 12 of the class would be procured, and described it as a ''не слишком перспективный локомотив'' (English: not very promising), though the railway had increased it requirement for dual system locomotives. Instead he announced that Transmashholding would be seeking a foreign company to create a joint venture to manufacture a new design - the ЭП20 (EP20), with an expected order of 230 units or more. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「EP10」の詳細全文を読む スポンサード リンク
