Onboard Broken Rail Detection Research and Development
The Federal Railroad Administration (FRA) sponsored a project, performed by Transportation Technology Center, Inc. (TTCI), to research the feasibility of an Onboard Broken Rail Detection (OBRD) concept. A parallel long term track impedance characterization effort was undertaken with the...
Development of Locomotive Powered Freight Car Electrical Power Supply System (EPSS): Method for Electrical Power Distribution on Freight Trains
The Federal Railroad Administration (FRA) previously demonstrated advanced, remotely controlled, electro-mechanical systems, such as hand brakes, angle cocks, and cut levers that can contribute to increased safety and improved efficiency of freight railroad operations. The main impediment to...
Side Impact Test and Analyses of a DOT-113 Surrogate Tank Car with Cryogenic Lading
The Federal Railroad Administration (FRA) conducted a side impact test of a surrogate DOT-113 tank car at the Transportation Technology Center, Inc. (TTCI) to evaluate the performance of the tank car under dynamic impact conditions and to provide data for the verification and refinement of a...
Human Error Analyses Associated with Locomotive Cab Automation
The Federal Railroad Administration (FRA) sponsored Alion Science and Technology to conduct a project to examine cab system automation displays and the risk of human error.
Function Allocation and New Roles for Humans in Rail Automation
The purpose of this work was to demonstrate improved system performance on a selected automated system by implementing a function allocation methodology that enables design of a display interface for that system that makes best use of human as well as machine capabilities.
