Railway Cognitive Radio to Enhance Safety, Security, and Performance of Positive Train Control
Robust and interoperable wireless communications are vital to Positive Train Control (PTC). The railway industry has started adopting software-defined radios (SDRs) for packet-data transmission. SDR systems realize previously fixed components as reconfigurable software. This project developed a...Next-Generation Foundations for Special Trackwork – Phase I

This document describes the results of a job analysis that was conducted for the position of railroad Passenger Conductor. Key aspects of the position were identified, including main tasks and knowledge, skills, abilities, and other characteristics (KSAOs) required to perform the job successfully....Fatigue Status of the U.S. Railroad Industry
This report draws on the results of several prior studies, all conducted with similar methodology, to characterize the prevalence of employee fatigue in the U.S. railroad industry. Data from logbook surveys of signalmen, maintenance of way workers, dispatchers, and train and engine service...Comparative Evaluation of Rail and Truck Fuel Efficiency on Competitive Corridors
This study provides a comparative evaluation of rail and truck fuel efficiency on corridors and services in which both modes compete. For the purposes of this study, competitive movements are defined as those of the same commodity having the same (or proximate) origin and destination (O-D) pairs....Characterization of Railroad Bridge Service Interruptions
The Federal Railroad Administration contracted Transportation Technology Center, Inc., to study bridge problems that cause accidents or service interruptions and to use this information to evaluate the need to develop bridge monitoring systems. Existing monitoring systems and other mitigation...Visualizing Railroad Operations: A Tool for Planning and Monitoring Railroad Traffic
This report provides an overview of the development and technology transfer of the Railroad Traffic Planner application, a visualization tool with string line diagrams that show train positions over time. The Railroad Traffic Planner provides support for scheduling activities and also includes near...Validation and Calibration of a Fatigue Assessment Tool for Railroad Work Schedules, Final Report
This report summarizes the results of a project to demonstrate a method to validate and calibrate a fatigue model. The project examined 30-day work histories of locomotive crews prior to 400 human factors accidents and 1000 nonhuman factors accidents. A biomathematical fatigue model estimated crew...PTC 220 MHz Radio: PTC Radio Control and Applications Software Package
