TMH DP2D Diesel Train Secures EAEU Certification In Russia

Moscow, Russia – Transmashholding’s DP2D diesel train has obtained Eurasian Customs Union certification after completing a 5,000 km endurance test and a June acceptance committee review. The certificate allows the DMU to operate in Russia and other Eurasian Economic Union member states. The train can be configured with two to six railcars and carries between 162 and 636 passengers.

What Does This Regulation Cover?

The DP2D certificate covers operation on non-electrified railway lines in Russia and other Eurasian Economic Union member states. The certification confirms compliance with the Eurasian Customs Union’s technical regulation on the safety of railway rolling stock, following a 5,000 km endurance test and assessment on the St Petersburg–Sortavala route by Russian Railways specialists. The June acceptance committee, including TMH, RZD, institutes, and competent authorities, awarded the DP2D the O1 designation. The final certification stage audited production capacities at the Kolomna and Demihovo plants, technical documentation, manufacturing processes, and rolling stock test results. The DP2D uses a TEP70BS diesel locomotive from the Kolomna Plant and passenger railcars from the Demihovo Plant, with a design speed of 120 km/h and an estimated service life of 32 years. The train’s capacity ranges from 162 to 636 passengers depending on configuration, and end railcars include two wheelchair-adapted seats each, USB Type-A and Type-C charging, air conditioning, tinted heat-insulating windows, LCD screens, optional bicycle racks, and an accessible eco-friendly toilet. A unified control system duplicates driving and monitoring functions in the locomotive and end railcar cabs, allowing the entire train set to be operated by a single crew of drivers.

Key Regulatory Data

How Does This Compare to Global Standards?

TMH’s DP2D certification under the Eurasian Customs Union technical regulation parallels the 3TE28 freight locomotive’s certification on November 21, 2023, under the same TR CU 001/2011 framework. The 3TE28 certificate allowed operation in Russia, Belarus, Kazakhstan, Kyrgyzstan, and Armenia, and confirmed readiness for batch production with an initial batch of 400 locomotives planned; it uses an 18-9DGM diesel engine developed by TMH Engine Engineering Centre and manufactured at Kolomensky zavod (Source: Railvolution, 2023). By contrast, the DP2D is a passenger diesel multiple unit for non-electrified lines, with 162–636 seats and a 120 km/h design speed, rather than a freight locomotive. Outside the EAEU, global high-speed rail investment rose 24% in 2025, with Asia-Pacific accounting for 63% of development activity (Source: Market Research Future, 2025). The high-speed rail market was valued at USD 57.04 billion in 2025 and is projected to reach USD 105.28 billion by 2035 at a 6.3% CAGR (Source: Market Research Future, 2025). Alstom reported record orders of EUR 27.6 billion in fiscal year 2025/2026, up from EUR 19.8 billion the previous year, indicating strong global rolling stock demand (Source: Railway Pro, 2025). In the US, Tri-Rail exceeded 4.5 million passenger journeys, its highest annual figure (Source: Rail Market, 2025). No comparable passenger DMU certification data for the EAEU was publicly available.

Editor’s Analysis

The DP2D certificate gives TMH a certified passenger DMU for low-density, non-electrified routes across the EAEU, a segment where flexible capacity matters more than high speed. Global high-speed rail investment grew 24% in 2025, but the DP2D targets regional corridors that often rely on aging diesel stock (Source: Market Research Future, 2025). TMH’s simultaneous certification of freight and passenger rolling stock under TR CU 001/2011 may simplify procurement for EAEU operators seeking a single supplier for mixed fleets.

FAQ

Q: What is the DP2D diesel train?
A: The DP2D is a diesel multiple unit built by Transmashholding with a TEP70BS locomotive and two to six passenger railcars. It carries 162 to 636 passengers, has a 120 km/h design speed, and is intended for non-electrified lines.

Q: When will the DP2D enter passenger service?
A: The certificate allows operation in Russia and other EAEU states, but no service-entry date was disclosed. The June acceptance committee awarded the O1 designation after a 5,000 km endurance test.

Q: Can the DP2D operate in countries outside Russia?
A: Yes, the Eurasian Customs Union certificate covers Russia and other EAEU member states: Belarus, Kazakhstan, Kyrgyzstan, and Armenia. This has not been officially confirmed for non-EAEU markets.
