National Grade Crossing Inventory Overview

The purpose of the U.S. DOT National Highway-Rail Crossing Inventory Program is to provide a uniform national inventory database that can be applied to the improvement of safety at highway-rail intersections.

The information can be used for  planning and implementation of crossing improvement programs by public and private agencies responsible for highway-rail crossing safety.

For Crossing Inventory purposes, a crossing is defined as those tracks that exist between a pair of the same type of warning devices.

On January 6, 2015, FRA published a Final Rule that requires railroads that operate one or more trains through highway-rail or pathway crossings to submit information to the Crossing Inventory about crossings through which they operate.  This includes information about previously unreported and new highway-rail and pathway crossings and the requirement to periodically update existing crossing data.  FRA also revised the Crossing Inventory Form and the FRA Guide for Preparing U.S. DOT Crossing Inventory Forms.  Click here for more information about the National Highway-Rail Crossing Inventory Reporting Requirements.
