Abstract This report describes the Track Geometry Measurement System (TGMS) developed for the Department of Transportation under contract no. DOT-TSC-1367. This report also contains a· summary of the results of the test program that was conducted to validate the TGMS under various static and dynamic conditions. The TGMS has the capability to measure or derive gage, crosslevel (superelevation), warp (twist), curvature, maximum operating speeds for curves, vehicle speed and elapsed distance at speeds from near 0 to 30 mph. The TGMS is equipped with an automatic location detection system to accurately reference detected track geometry exceptions to permanent fixtures of the track roadbed. The track geometry measurements are compared to the Federal Railroad Administration Track Safety Standards and all detected exceptions are reported in real time by the onboard digital computer.
