English

Subject field(s)
  • Measuring Instruments (Engineering)
  • Railroad Safety
CONT

Where hot wheel detectors are installed, the HWD scanners will be scanning trains for excessive heat caused mainly by sticking brakes. The HBD [hot box detector] computer will provide audible and visual indications of hot wheel alarm conditions.... Hot wheel detectors do not scan the bearing like the hot box detectors. The hot wheel detectors are aligned so that the scanning path is directly on the wheel about 6 inches above the rail.

Subject field(s)
  • Railroad Safety
  • Rolling and Suspension Components (Railroad)
CONT

The Hot Box Detector Analyzer(HBDA)... partially automates the analysis process of HBD Data. It operates in conjunction with the present digital HBD system installed in dispatching offices. Its purpose is to relieve the workload of the HBD operators by eliminating the manual examining of train tapes that have no defects. The HBDA will produce a tape for trains which have a high deflection, dragging equipment indication or faulty tape.
