If a bottom rod connection fails there is potential for a train derailment.
In the past, derailments from failed bottom rod connections have resulted in the Association of American Railroads’ mandating bottom rod safety supports per AAR Interchange Rule 10.
Failures can occur from an improperly applied, broken, or worn out cotter pin.
