On-Board Broken Rail Detection (OBRD) Research and Development
From October 2019 to May 2022, the Federal Railroad Administration (FRA) sponsored a research and development project, performed by Transportation Technology Center, Inc. (TTCI), to research the feasibility of an Onboard Broken Rail Detection (OBRD) concept at the Transportation Technology...
Feasibility of a Train Horn with Optimized Directivity: Environmental and Occupational Noise Benefit of an Ideal Train Horn
This report examines the feasibility of and recommends an acoustical specification for such an optimized horn. The detectability of the horn signal for motorists inside vehicles, the areas of environmental noise impact and occupational noise exposure have been compared for the optimized horn and...
Automated Track Centerline Following for Drone Flight Automation
VisioStack Inc. completed initial research to automate drone inspection flights over railroad track using real-time rail detection and track centerline following to simulate flight control without Global Positioning System (GPS) information. Uncrewed Aerial Systems (UAS, or drones) are platforms...
