Model-Assisted Probability of Detection for Ultrasonic Rail Flaw Detection
This report gives a roadmap for applying model-assisted probability of detection (MAPOD) to the ultrasonic detection of rail flaws. Researchers at ENSCO, Inc., selected this type of track inspection as the most suitable for the MAPOD approach.
MAPOD analysis involves identifying...

On December 22, 2020, at 11:40 a.m. PST, a westbound BNSF Railway (BNSF) loaded crude oil train experienced a broken train collision, which resulted in the derailment of 10 loaded crude oil tank cars near Custer, Washington.Feasibility of Applying Model-Assisted Probability of Detection to Track Inspection
Model-assisted probability of detection (MAPOD) is a method for evaluating the effectiveness of inspection processes. The Federal Railroad Administration (FRA), through a contract with ENSCO, Inc., researched the feasibility of applying the MAPOD approach to the inspection of track flaws. ENSCO...
