An Implementation Guide for Wayside Detector Systems

To promote wayside detector system implementation efforts, the Federal Railroad Administration (FRA) has constituted an FRA Future Team - Technology Working Group to progress technology focused research activities to further its safety mission. Under this initiative, FRA partnered with Metro North Railroad (MNR) and Long Island Rail Road (LIRR) to jointly identify opportunities to enhance safety through the analysis of their existing wayside detection systems. This guide includes brief descriptions of various wayside detection technologies, their capabilities and impact on rolling stock performance and operating safety. The requirements for installation site selection, data communication and storage, system thresholds and calibration/maintenance requirements are briefly described. The guide briefly reviews different wayside detector systems in North America’s rail network, including Acoustic Bearing Detectors (ABD) (Trackside Acoustic Detection System [TADS®], Railway Bearing Acoustic Monitor [RailBAM®]), Automatic Cracked Wheel Detector (ACWD), Dragging Equipment Detector (DED), Hot Box Detector (HBD)/Hot Wheel Detector (HWD), Truck Bogie Optical Geometry Inspection (TBOGI), Truck Hunting Detector (THD), Truck Performance Detector (TPD), Weigh-in-Motion Detector (WIM), Wheel Impact Load Detector (WILD), Wheel Profile Measurement System (WPMS), and Wheel Temperature Detector (WTD) systems; while more focus targeted WILD as an example of the best practices in the implementation of wayside detector systems.
