The Federal Railroad Administration plans to issue regulations that will address the most common human errors that cause train accidents.

"The new regulation will provide additional enforcement authority over violations of common operating practice errors," FRA Administrator Joseph Boardman said during a recent visit to CSX Transportation's Railroad Education and Development Institute in Atlanta. "This effort is one of many aggressive steps we are taking to prevent train accidents from occurring in the first place."

The agency is accelerating development of a rule that will focus on reducing the most common human errors, such as improperly lined track switches, shoving or pushing rail cars without properly monitoring for safe conditions and leaving rail cars in a position that obstruct an adjacent track, Boardman said.

The proposed regulations will be published by September, he noted.

Human factors are the leading cause of train accidents, accounting for 38 percent of the total, Boardman said. The new rule would be the first significant update of federal regulations governing railroad employee adherence to operating rules.

FRA says it also is actively working on other initiatives to reduce human factor-caused train accidents including a pilot project to study "close calls"
