For Alpha Trains, the agreement shifts propulsion maintenance into a more predictable lifecycle model, combining overhaul planning, spare parts supply and technical support under one long-term structure.
The deal covers the operational life of Alpha Trains’ diesel multiple units, all of which are powered by mtu PowerPacks from Rolls-Royce. The aim is to improve planning reliability, technical availability and maintenance predictability for fleets operated by different rail companies across Europe.
For operators leasing DMUs from Alpha Trains, the framework should provide a more structured maintenance setup. PowerPack overhauls will be integrated into Alpha Trains’ service-oriented leasing model, supporting higher fleet availability and more transparent long-term cost planning.
The mtu PowerPack combines the engine, power transmission and auxiliary systems, including cooling and exhaust aftertreatment, in one modular propulsion unit. For diesel multiple units, this makes overhaul quality a key factor in day-to-day reliability.
The agreement also includes broader service elements such as scheduling, warranty, spare parts supply, training for operator workshops and long-term cost development. Alpha Trains and Rolls-Royce will also work on technical solutions to identify and address potential obsolescence before it affects operations.
A further element of the deal is the option to operate all mtu 1800 series PowerPacks manufactured from 2006 onwards with HVO, a synthetic fuel produced from waste and residual materials. According to the companies, HVO can reduce CO₂ emissions by up to 90% compared with conventional diesel.
Jörg Hagemeyer, Engineering Director Passenger at Alpha Trains, said the agreement sends “a clear signal” about the quality and availability of the company’s diesel multiple units, while creating a more comprehensive service package for customers and operators.
Andreas Görtz, President of the Mobile & Sustainable business unit at Rolls-Royce Power Systems, said the partnership would support high quality standards, availability and efficient railway operations.
The deal reflects a wider trend in European rolling stock leasing, where availability, lifecycle maintenance and lower-emission operation are becoming increasingly important parts of the offer — not only the vehicles themselves.
