Freight cars: the mainstay of freight transportation.
Freight cars can be completely open or have permanent or removable roofs. They come in several different guises: flatcars for cargoes that can withstand exposure to the elements, ingeniously flexible transport solutions with sides that can be folded up or down as required, or container, refrigerator, tank and self-unloading cars. For manufacturers and operators alike, Knorr-Bremse is the partner of choice.
Manufacturers have long since developed freight cars for every type of application – and they are the mainstay of modern freight transportation. It is not uncommon for freight cars to remain in service for 50 years or more. This is made possible by their simple and robust design. Traditionally, freight cars have always been entirely analog, relying on manual operation rather than electrical equipment, and requiring a substantial marshaling effort. Manufacturers and operators are now working hard to push forward the electrification and digitization of freight cars. The big challenge is to ensure compatibility with analog cars..

The bogie equipment implements the vehicle driver’s braking command – the braking force converts kinetic energy into heat. In freight cars, this is made possible by special freight car brake actuators.
The brake control system employs the generations 'KE' and 'KE Classic' freight car control valves to provide optimal braking force distribution across the entire freight train. As an option, an integrated pneumatic derailment detection system per bogie ensures the highest safety standards for dangerous goods wagons.
With its extensive friction material portfolio, Knorr-Bremse can deliver brake blocks and pads that have been specially developed for freight car applications. Also we supply organic friction material (LL-blocks and K-blocks) to UIC- and AAR markets.
There is nothing digital about freight cars – in the past that was as certain as a red light ahead of a busy stretch of track. Now, though, in this segment too Knorr-Bremse is opening the door to digitization. The declared aim is to achieve greater efficiency along the entire transportation chain via Digital Freight Train .
Every freight car operator has its own unique profile and equally individual service requirements for the maintenance, overhaul and repair of its braking systems.
