Locomotive Crashworthiness Research Volume 3: Review and Discussion of Freight Locomotive Crashworhiness Concepts

The results of the study, summarized in this report, suggest that a cost-effective improvement in locomotive crashworthiness is feasible, at least for a few of the features. In particular, a performance specification that requires ductile collision posts with greater strength appears to yield the...

Locomotive Crashworthiness Research Volume 2: Design Concept Generation and Evaluation

The overall approach to the project included information gathering on locomotive design and crashworthiness; the development of computer models to evaluate crashworthiness; and the generation, evaluation, and prioritization of design concepts that could potentially improve locomotive cab...

Locomotive Crashworthiness Research Volume 1: Model Development and Validation

The model developed to simulate the head-on collision of two lead locomotives, each in a multi-locomotive, multi-trailing-vehicle train, appears to provide a good simulation of the resulting extent of override and crush in the lead locomotives. Results of this study show that trailing vehicles (...

Amtrak Fuel Consumption Study

This report documents a study of fuel consumption on National Railroad Passenger Corporation (Amtrak) trains and is part of an effort to determine effective ways of conserving fuel on the Amtrak system. The study was performed by the Transportation Systems Center (TSC) under the sponsorship of the...

Electronically-Controlled Pneumatic Brake Revenue Service Tests

This report, prepared by the Transportation Technology Center, Inc. (TTCI), Pueblo, Colorado, a subsidiary of the Association of American Railroads (AAR), summarizes the findings of the service testing of electronically controlled pneumatic (ECP) brakes, carried out between the spring of 1996 and...

Investigation of the Effects of Braking System Configurations on Thermal Input to Commuter Car Wheels

A heat transfer model, previously developed to estimate wheel rim temperatures during tread braking of MU power cars and validated by comparison with operational test results, is extended and appplied to cases involving several different blended brake system configurations. Preliminary and final...

Human Reliability Analysis in Support of Risk Assessment for Positive Train Control

This report describes an approach to evaluating the reliability of human actions that are modeled in a probabilistic risk assessment (PRA) of train control operations. This approach to human reliability analysis (HRA) has been applied in the case of a safety evaluation of the Communications-Based...

Railroad Dispatcher Communications Training Materials

Readback/hearback errors by railroad dispatcher and train crews or other track users can potentially result in accidents and derailments. The training materials developed under this project are designed to improve dispatcher communication skills with the goal of reducing the occurrence of readback/...

Selection of Railroad Dispatcher Candidates

This report presents the results of a study to explore approaches to railroad dispatcher trainee selection. The work was conducted in response to an indication from railroad industry representatives that there is a need for guidance in developing a dispatcher selection program, particularly with...

Human-Centered Incident Investigation Methods for the Railroad Industry: Conference Summary

This report presents a summary of a one-day educational conference on human-centered incident investigation methods for the railroad industry. Fifty-seven participants from the railroads, rail labor, government, and consulting/academia attended the one-day conference, held in Chicago, IL. Mr....
