On track worldwide – In inter-city and mass transit trains

For almost 60 years, we have supported the technological development of inter-city and mass transit trains. During this time, we have repeatedly created innovative products that modernized – and sometimes even revolutionized – rail transportation, for instance the first air suspension system for high-speed trains. We have expanded our product range and opened up markets on an ongoing basis. Today our suspension concepts for maximum safety and ride comfort have become permanent features in inter-city and mass transit trains as well as high-speed trains.

Examples of projects

Our innovative suspension concepts for controlling vibrations, isolating sound and improving comfort have become standard features of rail vehicles everywhere. They can be found in inter-city, mass transit and high-speed trains – in Europe and America as well as in Eastern Asia and Australia. We are the global leader in the rail vehicle industry.
