Analysis of Accelerations Measured During Full-Scale Tank Car Impact Tests

Tank car impact responses were investigated using accelerometers mounted at various locations on a tank car. Several tests were run with both a full and an empty tank car, and varying the tank car impact speed. The data from the accelerometers went through a power spectral density (PSD) analysis...

Repair of Budd Pioneer Coach Car Crush Zones: Rail Passenger Equipment Impact Tests

The research team conducted a project to repair cars for use in a full-scale train-to-train collision test with crash energy management systems. The two cars had been damaged in previous dynamic tests. Several components required replacement, and some required design modification. This report...

Safety of High-Speed Ground Transportation Systems: The Aerodynamic Effects of Passing Trains to Surrounding Objects and People

Two safety issues are raised on the aerodynamic effects of a passing train on its surroundings. First, a high-speed train passing other trains on an adjacent track exerts aerodynamic pressure that can affect the structural integrity of window mount and glazing, and the stability of the railroad car...

Quantitative Nondestructive Testing of Railroad Tank Cars Using the Probability of Detection Evaluation Approach

Through sponsorship by the Federal Railroad Administration and in cooperation with tank car industry representatives, Transportation Technology Center, Inc. (TTCI) has developed probability of detection (POD) curves for nondestructive testing (NDT) methods allowed under 49 CFR Sections 179 and...

Emergency Escape Breathing Apparatus

Through sponsorship by the Federal Railroad Administration and in cooperation with the railroad industry and railroad labor organizations. Technical Products, Inc. (TPI) has developed information and recommendations relative to the use of emergency escape breathing apparatus (EEBA) by train crews...

Regulatory Evaluation and Regulatory Flexibility Assessment for Use of Locomotive Horns at Highway-Rail Grade Crossings

One of the more persistent problems facing railroads and motorists is highway-rail grade crossing collisions and their resulting casualties. Public and private initiatives to improve grade crossing safety have increased motorist awareness of approaching trains at crossings. Of the nearly 154,000...

Summary Of Inventory Data Crossing Counts

General Health Effects of Transportation Noise

The Federal Railroad Administration (FRA) sponsored preparation of this report to support a rulemaking process about the use of locomotive horns and the accompanying environmental impact statement. This document reviews select current and past research on the effect of transportation noise on...

Updated Analysis of Train Whistle Bans - January 2000

Analysis of the Safety Impact of Train Horn Bans at Rail-Highway Grade Crossings: An Update Using 1997-2001 Data

This report updates Westat's prior report to FRA (Zador, 2002) in terms of both data and statistical methods. Safety impact estimates in the prior report were based on 5-year accident data for 1992-1996. In this report, safety impact estimates are based on recent grade-crossing accidents during the...
