Tools and Applications

  • Grade Crossing Inventory System (GCIS) – GCIS is a system used by railroads and state DOTs to provide characteristics and other information for highway-rail crossings on Form 71. Please note only railroads and state DOTs can access this system.
  • Quiet Zone (QZ) Calculator – The QZ Calculator is used to determine the characteristics/needs to set up a quiet zone within various U.S. municipalities.
  • Activation Failure/False Proceed (AF/FP) Reports – Railroads are required to report to the FRA whenever a signal system fails in a manner which results in a more favorable aspect than intended being displayed by a signal, or other condition hazardous to the movement of a train. These are occurrences referred to as a "False Proceed Signal Failure." In 1995, regulations went into effect requiring railroads to also report to the FRA whenever a highway-rail grade crossing warning system failed in a manner which results in little or no warning being provided to the public of an approaching train, or of one occupying a crossing. These are occurrences referred to as "Activation Failure." This tool contains railroad-reported activation failure and false proceed information.
  • National Significant Risk Threshold (NSRT) API – The National Significant Risk Threshold (NSRT) is an average of the risk indexes for gated public crossings nationwide where train horns are routinely sounded. The NSRT API may be used to download and review the specific crossing data used to calculate the NSRT values.
