In 2018, the Federal Railroad Administration’s (FRA) Office of Research, Development and Technology conducted a series of impact tests for different car configurations at various coupling speeds to better understand the load environment of tank cars during yard operations, and to identify hazardous operating scenarios. More than 700 impact tests were conducted. For each impact test, 40 data channels comprised of acceleration, force, speed, and strain data were recorded. This report presents the analysis of impact test data. The analysis considered longitudinal coupler forces as well as transferred energy between cars during yard operations for different draft gear types.
