Sonicar is a self-contained, automatic system for controlling the coupling speed of free rolling freight cars during switching operations. By assuring that coupling impacts take place below 4 mph, a dramatic reduction is expected in lading damage. The system is inactive during normal train operation and does not affect normal braking action. System concepts, operation, and field results are discussed.
