Acoustic Detection of Railcar Roller Bearing Defects: Phase I, Laboratory Test
A series of tests were performed at the Bearing Test Facility at the Transportation Technology Center,Inc. (TICI) in Pueblo,Colorado, to gather acoustic and acceleration emissions for a number of roller bearing defect types designated by the rail industry as a priority. This database will be used...A Preliminary Description of Stresses in Railroad Rail
One portion of the Federal Railroad Administration's (FRA) Track Performance Improvement Program is the development of engineering and analytic techniques required for the design and maintenance of railroad track of increased integrity and safety. Under the program management of the Transportation...Evaluation of FRA Trespass Preventation Research Study
The United States Department of Transportation’s (US DOT) John A. Volpe National Transportation Systems Center (Volpe Center), under the direction of the US DOT Federal Railroad Administration (FRA) Office of Research and Development (R&D), conducted an independent internal evaluation of the...Prototype Design of a Collision Protection System for Cab Car Engineers—Fabrication and Test
Advancements in the structural crashworthiness of passenger rail cars now make it possible to preserve the compartmentalized space occupied by a cab car engineer during a train collision. In order to translate this additional protection into improved survivability and mitigate injuries, it is...Campaign Monitoring of Railroad Bridges in High-Speed Rail Shared Corridors using Wireless Smart Sensors
This research project used wireless smart sensors to develop a cost-effective and practical portable structural health monitoring system for railroad bridges in North America. The system is designed for periodic deployment rather than as a permanent installation to enable campaign-style bridge...Operational and signal modifications for compliance with maximum authorized passenger train speeds and other speed restrictions
This is a safety advisory recommending actions that passenger railroads take to prevent trains from speeding. The advisory is the latest in a series of steps FRA has taken to keep passenger railroads safe for the traveling public.Federal Railroad Administration Recommends Actions to Prevent Passenger Trains from Speeding
WASHINGTON — The Federal Railroad Administration (FRA) today issued a safety advisory recommending actions that passenger railroads take to prevent trains from speeding. The advisory is the latest in a series of steps FRA has taken to keep passenger railroads safe for the...
