Bogie control systems

Influence important processes to improve the agility of your fleet

Passenger comfort measurement

The COSAMIRA system maps out the exposure to shocks and vibrations, providing an objective tool to measure and improve the passenger comfort on your fleet. The data can be used to actively move the car bodies in lateral direction (active lateral suspension), reducing shocks and discomfort.

Tilting

To enable trains to tilt when entering a bend, Televic Rail has designed a bogie sensor system detecting turns in the trajectory. The sensors measure the tilting behavior and monitor aspects like uneven tilt, wheel unloading and gauge infringement.

Active Radial Steering

COSAMIRA is also used to steer the wheels of the bogie, decreasing rail and wheel friction. The sensors measure lateral wheel acceleration and use this data to control the actuator steering the wheelsets.

Bogie hunting: Testing is vitally important

The dangers of bogie hunting are well recognised and on high speed trains the effect can be catastrophic.
Televic systems are proven to quickly and accurately detect this anomaly while providing warnings to crew and offering remedial stability of the system.

Risk reduction: Safety and Integrity Level 2

The Instability Monitoring System and the Total Tilting Failure Recognition are compliant to Safety Integrity Level 2 (SIL2). Televic Rail has delivered more than 3000 of these systems for Zefiro China and Zefiro Italy.
