Industry Sector: Railway technology and passenger transport.
Application Area: Braking architectures and train entrance systems.
Knorr-Bremse has secured a contract to supply critical system technologies for Siemens Mobility's new Vectouro passenger train platform. The mid double-digit million-euro agreement includes the provision of advanced braking architectures and entrance systems designed for cross-border intercity rail networks operating at speeds up to 230 km/h.
Braking Systems and Traction Control
The equipment contract encompasses the delivery of pneumatic and electronic braking hardware for the Vectouro carriages and their accompanying Vectron locomotives. The system architecture includes energy-efficient compressed air supply units, bogie equipment, and modern brake actuators. To maintain operational safety across diverse European rail networks, the hardware integrates advanced anti-slip protection mechanisms, ensuring secure traction and precise deceleration regardless of varying weather or track conditions.
Entrance Architecture and Aerodynamics
For passenger access, the trains will be equipped with pressure-tight swing-sliding door systems. Engineered specifically for high-speed, long-distance service, these entrances incorporate integrated boarding aids to facilitate efficient and accessible passenger flow. The pressure-tight sealing mechanism is a critical structural requirement to maintain cabin pressurization and aerodynamic efficiency when operating on modernized semi-high-speed corridors.

In high-speed and semi-high-speed rail operations (such as the 230 km/h Vectouro platform), pressure-tight swing-sliding doors are critical not just for acoustic insulation, but to protect passengers from severe barometric pressure transients. When a train enters a tunnel at high speed, it pushes a column of air that creates a compression wave; if the doors lack hermetic sealing, this rapid pressure fluctuation can cause significant aural discomfort (barotrauma) for the occupants. Furthermore, the "anti-slip protection" mentioned in the braking architecture is technically known as Wheel Slide Protection (WSP). Functioning similarly to an ABS system in heavy-duty vehicles, WSP utilizes rotary encoders to monitor individual wheelset velocities during braking. It dynamically modulates the pneumatic brake cylinder pressure to prevent the steel wheels from locking up and sliding along the rails. This prevents the formation of "flat spots" on the wheels—which would require expensive lathe reprofiling—and ensures the train does not dangerously overshoot its stopping distance.
