Categorizing Track Mud Spot Risk by Measurement of Vertical Track Deflection
This report presents the concluding results related to Phase 1 of the Federal Railroad Administration’s (FRA) Broad Agency Announcement (BAA) project Categorizing Track Mud Spot Risk by Measurement of Vertical Track Deflection. The overall goal of the project was to develop a means of using vertical track deflection measurement data to determine a risk value associated with a given mud spot in track, based on current vertical track deflection measurement capability. This in turn can then be used for prioritizing maintenance of identified mud spots. Specifically, for Phase 1 of the project, Harsco Rail’s goal was to both collect vertical track deflection measurement data and to use that data to develop an initial model framework, with a first order application from June 2016 through August 2020.
