ЭП2К (Электровоз Пассажирский (passenger electric locomotive), type 2, Коллекторный тяговый привод (collector traction drive)) is a Russian passenger six-axle DC electric locomotive produced by the Kolomna Plant. The first serial DC passenger electric locomotive in the history of Russian electric locomotive construction. The electrical part for EP2K is produced by the Novocherkassk Electric Locomotive Plant and the Kaluga Research and Production Electromechanical Plant.


By the early 2000s, on the electrified railways of Russia, the basis of the fleet of passenger electric locomotives were locomotives produced by the Czechoslovakian Škoda plant. While two-section eight-axle electric locomotives ChS6, ChS7 and ChS8, produced in the 80s and 90s, were used to drive long trains, single-section six-axle electric locomotives ChS2 and ChS2T were used to drive medium-length trains on direct current lines and ChS4/ChS4T on AC lines, many of which were produced during the 60s and 70s and were therefore largely worn out and obsolete. Electric locomotives ChS2 and ChS2T were operated primarily on the Moscow and Oktyabrskaya railways with the most intense passenger traffic, which contributed to their wear and tear and required replacement with new locomotives of a similar class. Therefore, along with the deep modernization of the ChS2 electric locomotives at the Yaroslavl Electric Locomotive Repair Plant, Russian Railways decided to design new Russian-made locomotives.

The main manufacturer of electric locomotives in Russia was the Novocherkassk Electric Locomotive Plant, but at the beginning of the 2000s its efforts were devoted to the production of passenger AC electric locomotives EP1 and the creation of new AC freight electric locomotives E5K and 2ES5K. Therefore, the Kolomna Plant, which had extensive experience in the production of passenger diesel locomotives with electric transmission, was chosen to create DC electric locomotives. A year earlier, the plant produced a new passenger diesel locomotive TEP70BS (originally TEP70A), which is a deep modernization of the well-proven TEP70 diesel locomotives. Even earlier, in the late 1990s, the plant produced two experimental high-speed AC passenger electric locomotives EP200, which performed well in tests, but turned out to be unclaimed due to the lack of high-speed AC lines.

In 2003, OAO Russian Railways entered into a contract with the Kolomna Plant to create a new six-axle passenger electric locomotive, with technical characteristics similar to the ChS2T electric locomotives. The new promising diesel locomotive TEP70BS was chosen as the basis for the design of the mechanical part. Electrical equipment for the locomotives was to be supplied by the Novocherkassk plant. Design work to create the locomotive was completed in 2005 simultaneously with the completion of certification of the TEP70BS-001 diesel locomotive.


Production of the first prototype of the EP2K electric locomotive began at the end of 2005, simultaneously with the plant’s transition to serial production of TEP70BS diesel locomotives. At the beginning of 2006, the assembly of the electric locomotive was completed, and on February 3 its presentation at the plant took place. After this, the electric locomotive was sent for testing. Soon, in 2007, a second electric locomotive was produced, which was also sent into trial operation. During testing, the EP2K electric locomotives showed compliance of the design technical and operational characteristics with the technical specifications, after which the electric locomotives were successfully certified and recommended for mass production.

Since 2008, the plant began serial production of locomotives of this series, which continues to this day. Electric locomotives numbered 028 left the factory in white, 029 – in red, 030 – in white, 031 – in red, 032-036 – in white, 037-100 received a red color, 101 – corporate, 102-108 – red, EP2K from 109th are painted in corporate red and gray livery.
