Controlled railcar derailments, at train speeds ranging from 2.2 - 13 m/s (5-30 mph), were conducted. The Naval Surface Weapons Center's participation in this work, which also included roller bearing hotbox tests, resulted from the Department of Transportation System for Train Accident Reduction (DOT-STAR) program. This report includes the measurement of local derailment shock and the evaluation of two derailment detector designs. Acceleration was recorded at six locations during nine derailments. The rail-contact type derailment sensor tested worked well. A prototype displacement-sensing derailment detector also functioned properly, although not exactly as expected due to a triggering threshold problem.
