Hot Box & Hot Wheel detectors (HBD & HWD) are measuring devices installed along the line and designed to monitor axle, wheel and brake temperatures indicating any overheating which could lead to train accidents.
System consists of detection units located inside a special sleeper and a processing unit located at the trackside which collects the values measured by the detectors and transmits this data to the traffic control and monitoring section.
Hot Box & Hot Wheel Detectors are based on a system which measures the temperature by infrared radiation. The detection principle enables assessment of the degree of overheating and determination of an alert level, and sends the information to the central or local control/monitoring office.
