• Abstract:
  The Federal Railroad Administration (FRA) has determined that there is a research need to collect and analyze statistical usage ; data to help ascertain the cumulative load-induced fatigue on rail track segments. The estimation of rail segment burdening ; through the determination of loaded or unloaded wheel passages is aided by obtaining totalized statistical counts that can serve as ; an early indication of potential track failures. This research focused on designing and extensively testing a small, self-powered ; track assessment gauge (TAG) device that was installed directly to the web of the track rail. This device was designed to tabulate ; train wheel passages and associate an “empty” or “loaded” status with passage of rolling trains. The measured statistical data was ; stored internally to the device and was field accessible for recovery via a non-contact hand-held unit. Additional testing is needed ; to confirm the actual power consumption during operation and sleep modes, and verify the operation and accuracy of the TAG ; unit in varied track/roadbed conditions.
