At the Bryansk Machine-Building Plant (BMZ, part of Transmashholding), assembly has begun on a prototype of the first domestically produced mainline gas-diesel locomotive, the 3TE30. The three-section locomotive, capable of operating on both liquefied natural gas and diesel fuel, is expected to take to the rails as early as 2026.
The power plant of the new machine develops 3,300 kW — enough to confidently haul a train weighing up to 7,100 tonnes. The developers emphasize that the 3TE30 will become one of the most economical and environmentally friendly mainline diesel locomotives on the Russian Railways network: the switch to gas will make it possible to significantly reduce liquid fuel consumption and harmful emissions.
Assembly of one of the head sections is already underway in Bryansk. The middle, gas-powered section was designed by Kolomna's VNIKTI. The overall design documentation for the locomotive was prepared by "TMKh Inzhiniring". Specially for the 3TE30, the Engine Engineering Center created the 16GDG gas-diesel generator, which is currently undergoing bench tests. The Novocherkassk branch of "TMKh-Inzhiniring" is responsible for the microprocessor control system, while the Novocherkassk Electric Locomotive Plant (NEVZ) is manufacturing the wheel-motor units.
Three sections, a powerful gas-diesel power plant, and modern digital solutions make the 3TE30 the leading contender for the role of heavyweight on long-distance freight routes. After successful testing, the new locomotive will be able to significantly modernize the Russian Railways traction rolling stock fleet and become a notable step by Russia toward more environmentally friendly and economical railway transport.
