"A recent catastrophic railroad accident occurred in Canada when an unattended freight train containing hazardous materials rolled down a descending grade and subsequently derailed. It is currently estimated that this accident resulted in 42 fatalities, and 5 persons are still reported to be missing. In response, FRA [Federal Railroad Administration] issued Emergency Order No. 28 regarding the securement of trains, and FRA and PHMSA [Pipeline and Hazardous Materials Safety Administration] (collectively, DOT [Department of Transportation]) are also issuing this safety advisory. This safety advisory discusses the circumstances surrounding the accident and makes certain safety-related recommendations to railroads operating in the United States. This safety advisory also provides notice of FRA's intent to schedule an emergency meeting of the Railroad Safety Advisory Committee to discuss this accident and potential regulatory actions to prevent similar future accidents from occurring."
