Revenue Service Evaluation of a Truck Component Inspection System
The Federal Railroad Administration, in collaboration with the Association of American Railroads and project coordinator Transportation Technology Center, Inc., has sponsored a revenue service test of an automated, machine vision inspection system for evaluating truck components on railcars. The...
Side Impact Test and Analyses of a Legacy DOT-113 Tank Car
On November 19, 2019, the Federal Railroad Administration (FRA) contracted Transportation Technology Center, Inc. (TTCI) to conduct a side impact test of the DOT-113C120W (DOT-113) cryogenic tank car to evaluate the performance of the tank car and to provide data for the verification and...
Secondary Impact Protection for Locomotive Engineers – Improved Airbag Design
As part of the Federal Railroad Administration’s locomotive cab occupant protection research, a Secondary Impact Protection System (SIPS) for locomotive engineers was developed. The system uses an automotive-style passenger airbag and a deformable knee bolster to provide the desired protection...
Railroad Freight Car Remote Controlled Electrically Driven Set & Release Hand Brake (EDHB) – Wireless Control Development
This report discusses the development of prototype Electrically Driven Hand Brakes (EDHB) that provide remote automatic set and release functions from push buttons mounted on the side of a car, or wirelessly. The EDHB improves the safety of railroad operations in several ways, including making...
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...
