Customized gearboxes

Power – optimally transformed onto the rail

The power of a railway vehicle depends on the quality of the drive train. Our transmission solutions have proven themselves for decades on international markets.

Technical expertise and innovative solutions

By means of modelling and simulation, the gearboxes are weight- and noise-optimized. The use of innovative and proven approaches as well as the use of durable components reduces maintenance costs to a minimum and ensures the high reliability of our rail transmissions. All drive components are designed for the entire service life of the vehicles – with the exception of wearing parts.

A reliable partner for our customers

Our mission is to ensure high delivery reliability and to interact quickly with our customers based on certified processes and quality standards. Our partnership with our customers also includes a comprehensive range of services (maintenance, repair, and spare parts) after delivery of the gearboxes.

Close the customer – our global positioning makes it possible to localize production. Service workshops among others in Germany, the USA, Great Britain, and Russia ensure that we can provide service close to the customer.
