What does AFTC mean in TRANSPORTATION

AFTC stands for Audio Frequency Track Circuits, which are widely used in railway systems to detect the presence of trains on tracks.

AFTC uses electrical signals and audio frequencies to keep track of train location in order to prevent collisions, ensure safety, and optimize train operations. This information then sends data back to the control center for monitoring and tracking purposes.

Advantages of using this system include improved safety and decreased delays caused by collision risk or human error. Additionally, the system is cost effective as it reduces energy costs associated with traditional rail management systems.

An AFTC system requires some basic components like sensors along the trackways that detect passing trains; transducers which convert pressure waves into electrical signals; a transmitter that updates the conditions along each track; a central control station where all data is gathered; and receivers distributed along the rails that send information back to the control station from different points on the trackways.

Regular maintenance should be performed on an AFTC system in order to assess its health status and ensure smooth functioning. This includes regular inspections of sensors, transducers, transmitters, receivers, cabling etc. Properly maintained equipment also helps avoid unexpected downtime or faulty readings due to wear and tear over time.
