Why do more and more high-speed train manufacturers and operators put their faith in Knorr-Bremse systems


Rail Vehicle Systems

Knorr-Bremse systems are impressive even at extremely high speeds At speeds of up to 400 km/h, enormous forces are generated. Trains that regularly travel long distances at high speeds require braking systems that can keep these forces under control – both safely and economically. As well as lightweight, compact systems that can be used worldwide, there is a need for intelligent control systems. Knorr-Bremse is regarded as an international pioneer in this field. On the basis of tried-and-tested technologies, we develop innovative solutions offering top levels of safety, reliability, and economy. The systems we have developed are so efficient that they also score top marks in terms of environmental friendliness. Customers enjoy full support from a single source – from the initial planning stage and commissioning right down to aftermarket services. Worldwide operator and customer audits regularly single out the consistent quality of our products and services for praise – and this is confirmed by our EN 50126 (RAMS and LCC) certification.
