Automated Video Inspection System for Grade Crossing Safety

The Federal Railroad Administration (FRA) has sponsored several programs to help reduce incidents at highway-rail crossings and improve the safety of both vehicles and pedestrians. One such recent project developed an artificial intelligence (AI)-based machine vision system to help inspect...

Analysis of Historical Non-Destructive Evaluation Probability of Detection Data for Railroad Tank Cars

From 1996 to 2016, Transportation Technology Center, Inc. (TTCI) analyzed historical probability of detection (POD) data for the fusion welded tank car butt welds (BW) and fillet welds (FW) inspection using Code of Federal Regulation (CFR)-approved nondestructive evaluation (NDE) methods. The...

Analysis of Historical Non-Destructive Evaluation Probability of Detection Data for Railroad Tank Cars: Appendices A Through I

This appendices summarizes the number of observations, misses, hits, and false calls for each interval for fillet welds (FW) for all operators and for each nondestructive evaluation (NDE) method applied in Appendix A. Appendix B summarizes the median frequency of hits and misses for the...

Automated Broken Spike Detection – Phase I

Rail spikes connect railroad rails to the supporting crossties and secure tie plates and crossties together. Recent field inspections and observations have revealed broken spike failures (cut spikes and drive/screw spikes) when used with elastic fastener tie plates in mountainous, high-degree...

Compliance Testing for Locomotive LED Headlights and Auxiliary Lights, Phase IV

This report describes the work performed during Phase IV compliance testing of light-emitting diode (LED) fixtures used as locomotive headlights and auxiliary lights. The purpose was to study the performance of the lamps under severe cold weather conditions. Researchers sought to determine...
