Multiple rail units that connect urban areas and link them with their hinterland face tough challenges – and the requirements multiple unit manufacturers made of the vehicles’ systems are similarly demanding. What is needed are lightweight, compact systems that will operate anywhere in the world but are also precisely adapted to local conditions. This is where Knorr-Bremse’s flexible systems come and operators putting their in. On a 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 they also score top marks for environmental friendliness. Customers faith in Knorr-Bremse enjoy full support from a single source – from the initial planning stage via commissioning right down to aftermarket services. Operator and customer audits world-wide regularly single out the consistent quality of our products and services for praise systems – and this is confirmed by our EN 5016 (RAMS & LCC) certification. ?

What is Knorr-Bremse’s complete “one-stop solution” A perfect balance of high-quality systems and services. Knorr-Bremse’s expertise in the field has gone into every single component and system. Top-quality components operate for EMU/DMUs smoothly together to guarantee optimum functionality, high reliability and maximum safety. Complex electronic control sys- tems such as blending and brake management reduce wear to a minimum by ensuring balanced operation of all systems. The system can be configured either to use the vehicle bus system or a separate bus exclusive to the braking system. For each pro- ject, customers are closely consulted at the design stage. And it goes without saying that Knorr-Bremse offers support during the homologation process as well as all the necessary on-site services across the entire product lifecycle. ? 5 Multiple Units | EMU/DMU Rail Vehicle Systems Leading-edge technologies Sandra Salmen Compressors Bogie Equipment Brake Control B r a k e M a n a g e m e n t Project Engineer Electronic “Increasingly complex technologies, More compact, lightweight Maintenance-free brake calipers, Economical control with ESRA Intelligent braking less time for planning and imple- and economical low-wear pads and EP Compact mentation and a squeeze on prices - we can only cope with these pres- Knorr-Bremse offers a wide range of The WZK/RZS compact brake caliper unit Knorr-Bremse electronic systems have Economical braking is all about reduc- sures by making our processes more compressors including screw compres- has a completely redesigned operating significantly increased the safety, com- ing the stress on wear components to efficient.

Brake pads and discs require replacement more rarely, and their design enables them to be serviced rapidly. The brake calipers themselves require low maintenance. These in terms of economy examples demonstrate that if all the relevant factors are included in the calculation, the bottom line is savings for the custo- mer. Customized service packages ensure that all Knorr-Bremse systems function smooth- ly for anything up to 0 years – anywhere in the world. The secret is our combination of OEM expertise and a highly efficient service infrastructure. 6 ? Multiple Units | EMU/DMU Rail Vehicle Systems Satisfied customers ...
