AFTAC II Train Detection

A new generation of audio overlay detection
The Audio Frequency Train Activated Circuit (AFTAC) II system is GE’s new and improved FM audio overlay technology for train detection. The AFTAC II model is especially effective for locations with a heavily saturated channel spectrum. It may be applied with systems that control crossing warning devices at highway/railroad grade crossings and in train control systems where overlay train detection is needed.
