Voith and Liebherr Sign Cooperation Agreement for the Development, Distribution and Service of Diesel Engines for Rail Vehicles

  • This cooperation brings Voith’s know-how in the rail industry together with Liebherr’s long-standing experience in engine manufacturing
  • Diesel engines are compliant with globally applicable exhaust gas regulations, including the exhaust standard “Stage V” for rail vehicles in the European Union

Voith and Liebherr enter a cooperative partnership for the development, distribution and service of modern diesel engines for rail vehicles. Liebherr Machines Bulle SA (Switzerland) and Voith Turbo GmbH & Co. KG (Germany) signed a corresponding cooperation agreement in September 2017. Within the context of this agreement, Liebherr will in future supply several versions of its basic engine in the 500 kW power class as well as components for the exhaust gas aftertreatment system. The basis for this is the latest generation of a 6-cylinder in-line engine from Liebherr.

In the course of the cooperation, Voith, as a supplier of RailPacks, will be taking over responsibility for the diesel engine and exhaust gas aftertreatment system. Voith RailPacks are compact drive systems designed for railcars or special rail vehicles, comprising a diesel engine with an exhaust gas aftertreatment system, a transmission or generator and a cooling system as their main components. In addition, Voith will also be offering the engines as low-emissions drive solutions for a number of other rail vehicle applications. This means that Voith not only takes over responsibility for the overall system, but also for global distribution and servicing of the rail engines.

“By cooperating with Liebherr, we are offering our customers a modern and future-oriented solution for diesel engines in rail technology in conjunction with our new hydro-mechanical transmission,” explains Cornelius Weitzmann, Executive Vice President & CEO Mobility of the Voith Turbo GmbH & Co. KG. “Together, we will achieve compliance with future exhaust gas regulations in rail traffic and thus make our contribution to higher efficiency and sustainability.”

“With this new development, both long-established companies reaffirm their technological leadership positions,” says Rudolf Ellensohn, Director Combustion Engines of the Liebherr Machines Bulle SA. “We are particularly proud that our product is already so trusted, even today, and that we are able to meet the specific requirements of the rail traffic sector.”
