en.Wedoany.com Reported - Knorr-Bremse has recently secured a contract to supply brake systems and door systems for Siemens Mobility's new Vectouro passenger train platform. This medium-value agreement, worth tens of millions of euros, covers the provision of advanced braking architecture and entry systems for cross-border intercity rail networks operating at speeds of up to 230 km/h.

The contract includes the supply of pneumatic and electronic brake hardware for Vectouro carriages and the accompanying Vectron locomotives. The system architecture encompasses energy-efficient compressed air supply units, bogie equipment, and modern brake actuators. To maintain operational safety across various European rail networks, the hardware integrates advanced anti-slip protection mechanisms to ensure safe traction and precise deceleration under different weather or track conditions.

To facilitate passenger boarding and alighting, the trains will be equipped with air-tight plug door systems. These entrances, designed for high-speed long-distance services, integrate boarding assistance devices to promote efficient and convenient passenger flow. The air-tight sealing mechanism is a critical structural requirement for maintaining carriage pressurization and aerodynamic efficiency during modern semi-high-speed corridor operations.

In high-speed and semi-high-speed railway operations, air-tight plug doors are essential not only for sound insulation but also for protecting passengers from severe air pressure transients. When a train enters a tunnel at high speed, it pushes a column of air, generating a compression wave; if the doors lack sealing, this rapid pressure fluctuation can cause significant auditory discomfort for passengers. The "anti-slip protection" in the braking architecture is technically known as Wheel Slip Protection (WSP), functioning similarly to the ABS system in heavy vehicles. WSP uses rotary encoders to monitor individual wheel pair speeds during braking, dynamically adjusting pneumatic brake cylinder pressure to prevent steel wheels from locking and sliding on the rails, thereby preventing the formation of flat spots on wheels and ensuring the train does not exceed its stopping distance.
