Exceptionally precise and responsive train tilting systems maintain car stability and optimize passenger comfort when high-speed trains travel around curves.

Apply Small Movements to Make a Big Difference

  • A sophisticated sensor system automatically detects changing motion as the train approaches curves in the tracks
  • A central train-tilting computer determines the optimum tilting angle for each train car and transmits the information to each car
  • Individual train-tilting computers in each car almost imperceptibly tilt the car toward the inside of the curve at an angle of up to +8 degrees to optimize car stability and passenger comfort

Keep Business Moving as Fast as Trains

Avoid slowing down high-speed trains as they round curves to reach destinations faster and improve business:

  • Improve passenger safety and comfort by eliminating the sudden, unexpected movements of people and objects that can occur on high-speed curves
  • Increase passenger satisfaction and meet business objectives by keeping trains on schedule
  • Reduce capital costs by taking advantage of existing train tracks
  • Reduce maintenance costs with highly reliable, highly modular, compact, and lightweight components

Make Safety a Priority

Choose train tilting technology that is designed to IEC, VG, and EN standards, and incorporates key safety features:

  • Position encoders are read-in over two paths: RS-485 and pulse count
  • Hardwired and watchdog-controlled components automatically shut down the system if failures are detected
  • Safe RS-485 data links with synchronous data link control (SDLC) mode, life sign transmission between all system components, and CRC-16 on the application layer secure and validate system communications
  • Built-in test (BIT) capabilities augment external tests
  • Continuous comparison of positioning equipment information and second position encoders verifies data accuracy

Combine Power and Efficiency

Put advanced power features to work to keep tilting trains running smoothly:

  • Reduce costs with low power consumption
  • Reduce space requirements for power supplies with high power density
  • Reduce interference with separate power and signal electronics
  • Ensure safer handling with a low-voltage power supply
