DETECTORS FOR ACCIDENT PREVENTION

For dragging equipment detection, a series of brittle, cast-iron loops are mounted between and outside the rails, just below standard clearnace for rolling stock. Hanging parts break one or more of the detector loops and these being connected in a detector circuit de-energise a relay and operate warning devices. A device that automatically detects broken wheel flanges as well as wheels that are loose on the axle, while wagons are in motion, is described. The hot box detector has proved that the principles employed have been most successful in detecting hot axleboxes. The equipment was designed by a firm who are manufacturers of infra-red control systems.
