Paper Abstract

To improve detection of railroad track defects that cause derailments, the Federal Railroad Administration Office of Research and Development with joint cooperation of the railroad industry developed the Gage Restraint Measurement System (GRMS). This system measures the track's ability to support gage widening forces and marks the locations at risk for derailment. This paper describes the GRMS design, calculated safety indices, and application for use in maintenance planning.
