Hybrid for Coradia Lint

Abellio, Alstom, Nahverkehrsservice Sachsen-Anhalt GmbH and MTU plan to implement a new hybrid drive solution on Abellio’s fleet of Coradia Lint diesel trains.
The Coradia Lint is a fuel-efficient diesel multiple unit (DMU) that can reach operating speeds of up to 140 kph. It is powered by two MTU PowerPacks, each based on the MTU Series 1800 engine that meets the strict requirements of the current EU Stage IIIB emissions directive. The Hybrid PowerPack is an even more environmentally friendly version of this proven drive system: It combines an MTU diesel engine plus an electric machine, which can be used either as an electric motor or generator, and the MTU EnergyPack battery system, which stores the energy recovered during braking. This enables very low-noise, emissions-free battery-only electric operation in urban areas and around stations. The total operating costs of rail vehicles with MTU hybrid drives are also significantly lower. Even brake pads and discs have reduced wear due to brake energy recuperation. Because of the additional power of the electric machine, train operators also have the possibility to make up time delays using the improved drive dynamics and acceleration.
The Coradia Lint is part of Alstom’s Coradia range of modular trains which benefit from more than 30 years of service experience and proven technical solutions. Over 2800 Coradia trains have been sold to date, with 2300 of them currently operating in Denmark, France, Germany, Italy, Luxembourg, the Netherlands, Sweden and Canada.
