The EP10 (Russian: ЭП10) is a type of dual voltage six axle electric locomotive built for Russian Railways (RŽD) by NEVZ in association with Adtranz/Bombardier for passenger use. The design was considered costly, and only 12 units were acquired. 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. Decree number 1400 (23 November 1996) of the Government of the Russian Federation "Development and production of new generation passenger rolling stock at Russian enterprises", 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 OJSC VELNII and OJSC 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 EP2 (Russian: ЭП2) and EP3 (Russian: ЭП3) would be developed based on the asynchronous traction technology introduced in the EP10. 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.
