The asymmetrical antidrag mechanism is designed to detect when a passenger is being pulled from outside the train. This targeted detection helps prevent serious accidents by ensuring the doors only reopen in response to external drag forces, not internal movement or interference. As a result, the system reduces false activations and improves overall train availability. Its reduced sensitivity to internal tampering or vandalism also enhances operational reliability, particularly when doors are closed and locked.

The system is compatible with both pure sliding and sliding plug door configurations and can be integrated into existing train setups with minimal installation effort. Its design supports smoother door operation and helps eliminate incorrect detections that could delay train departures. By focusing on accurate risk identification and adaptability, the system contributes to improved passenger safety and more consistent train performance.
