Human Error Investigation Software Tool (HEIST)

Human factors are a leading cause of train accidents and incidents in the United States. Human factors go beyond the crewmembers who operate the on-track equipment. They include management support and oversight, operating practices and procedures, technologies and facilities, and the work culture—...

Conceptual Development Impact Overload Detection Devices for Tank Car Service

The objective of this project was to develop concepts for mechanical and electronic systems that can detect yard or in-train impacts that exceed design load or other reasonable limits on tank cars. The project team developed some mechanical and electronic systems for detecting overload impacts. For...

In-Track Demonstration of Laser-Treated Rail to Reduce Friction and Wear

In-track evaluations of a laser-treated rail intended to provide a permanent reduction of the friction level and increased wear life were conducted at the Transportation Technology Center’s Facility for Accelerated Service Testing, Heavy Axle Load track in Pueblo, CO. These evaluations were...

Development of a Preliminary Set of Human Factors Functional Design Guidelines for Remote Control Locomotive Systems

Due to our recent website upgrade some of the links in legacy documents might point to the decommissioned site location. We recommend that users take advantage of the search engine above to locate the material they seek on the current website. Be assured that we are working...

Detailed Modeling of the Train-to-Train Impact Test: Rail Passenger Equipment Impact Tests

This report describes the results of a finite element-based analysis of the train-to-train impact test conducted at the Federal Railroad Administration’s Transportation Technology Center in Pueblo, CO, on January 31, 2002. The ABAQUS/Explicit dynamic finite element code was used to simulate the...

Rail Crew Resource Management (CRM): The Business Case for CRM Training in the Railroad Industry

Crew Resource Management (CRM) is a human factors training process that has been employed in the commercial aviation industry for over 25 years. During that time period, CRM has been credited with contributing to a marked decrease in human factors-caused accidents. Military teams, commercial...

Tank Car Operating Environment Study: Phase I

This report documents the results of controlled testing conducted during the first phase of a tank car operating environment program involving the Association of American Railroads, the Railway Supply Institute (formerly the Railway Progress Institute), the Federal Railroad Administration, and...

In-Service, Over-the-Road Testing of One Car for Tank Car Operating Environment Study (Phase IIA) Test Results

This report documents the procedure and results of the controlled testing conducted during Phase II of a tank car operating environment program involving the Association of American Railroads, the Railway Supply Institute (formerly Railway Progress Institute), the Federal Railroad Administration,...

Passenger Cab Car Grade Crossing Impact Test Report: Rail Passenger Equipment Impact Tests

Two full-scale oblique grade crossing impact tests were conducted in June 2002 to compare the crashworthiness performance of alternative corner post designs on rail passenger cab cars. On June 4, 2002, a cab car fitted with an end frame built to pre-1999 requirements impacted a steel coil at...

Stub Sill Railroad Tank Car Research Project: Full-Scale Damage Tolerance Test

The Federal Railroad Administration, with supplemental support from the Association of American Railroads (AAR), Railway Progress Institute, and Chemical Manufacturers Association, contracted with the Transportation Technology Center, Inc., a subsidiary of AAR (then organized as AAR, Transportation...
