Evaluation of Options for Improving Amtrak’s Passenger Accountability System

In investigating the derailment of Amtrak's Auto Train on April 18, 2002, the National Transportation Safety Board (NTSB) reported that an accurate count of persons on the train at the time of the accident was not available at the accident scene. NTSB noted that emergency response would be...

San Joaquin, California, High-Speed Rail Grade Crossing Data Acquisition Characteristics, Methodology, and Risk Assessment

This report discusses data acquisition and analysis for grade crossing risk analysis at the proposed San Joaquin High-Speed Rail Corridor in San Joaquin, California, and documents the data acquisition and analysis methodologies used to collect and analyze grade crossing data and evaluate the...

Fatigue Crack Growth Behavior of Railroad Tank Car Steel TC-128B Subjected to Various Environments: Volume I

As part of an effort to apply damage tolerance concepts to railroad tank cars, the fatigue crack growth (FCG) behavior of two lots of TC-128B steel was investigated. In addition to the material lot difference, variables assessed include: load ratio, orientation, environment, and crack growth test...

Fatigue Crack Growth Behavior of Railroad Tank Car Steel TC-128B Subjected to Various Environments: Volume II - Appendices

This is Volume II-Appendices of Fatigue Crack Growth Behavior of Railroad Tank Car Steel TC-128B Subjected to Various Environments. This document contains miscellaneous supporting documentation, fatigue crack growth laboratory data, and analyses.

Variable Amplitude Fatigue Crack Growth Characteristics of Railroad Tank Car Steel: Volume III

The load history that railroad tank cars experience has a significant variable amplitude characteristic. Although previous efforts have been directed toward understanding baseline fatigue crack growth behavior of TC-128B steel as a function of material lot, orientation, and environment, little is...

Human Factors Root Cause Analysis of Accidents/Incidents Involving Remote Control Locomotive Operations

This report presents findings from a human factors root cause analysis (RCA) of six train accidents/incidents—collisions, derailments, and employee injuries—that involved remote control locomotive (RCL) operations in U.S. railroad switching yards. Descriptive data from participating railroads...

Investigation of Cracks in Acela Coach Car Brake Discs: Test and Analysis Volume II - Appendices

In April 2005, visual and laboratory tests identified cracks in the spokes of several brake discs on coach cars within Amtrak’s Acela trainsets, the high-speed trainsets operating on the Northeast Corridor. Amtrak halted operations of the Acela fleet until an assessment of the cracked spokes...

Investigation of Cracks in Acela Coach Car Brake Discs: Test and Analysis Volume I - Final Report

Remote Control Locomotive Operations: Results of Focus Groups with Remote Control Operators in the United States and Canada

This report presents findings from focus groups with remote control operators (RCOs) in the United States and Canada. The purpose was to learn more about remote control locomotive (RCL) operations safety-related issues, lessons learned, and best practices from those most familiar with the...

A Comparative Risk Assessment of Remote Control Locomotive Operations versus Conventional Yard Switching Operations

This report presents a comparative risk assessment of U.S. remote control locomotive (RCL) and conventional yard switching operations. First, a hierarchical task analysis (HTA) was conducted to provide a detailed description of yard switching tasks. Based on the HTA results, a preliminary hazard...
