Action
Notice of adjustment of Nationwide Significant Risk Threshold.
Summary
FRA is updating the Nationwide Significant Risk Threshold (NSRT) for purposes of FRA's regulation on the Use of Locomotive Horns at Public Highway-Rail Grade Crossings. This action is needed to ensure the public has the proper permissible risk threshold to evaluate risk resulting from prohibiting routine locomotive horn sounding at highway- rail grade crossings located in quiet zones. This is the ninth update to the NSRT and it is increasing from 13,811 to 15,488.
