Positive Train Control offers many safety and operational features that are designed to significantly enhance system reliability and network efficiency for heavy haul rail operations. PTC is intended to provide incremental improvements in train control through a modular design. A manual block...
Methods for detecting and quantifying the levels of conductive electromagnetic interference produced by solid state rapid transit propulsion equipment and the susceptibility of audio-frequency signaling systems to these emissions are presented. These methods include procedures for taking...
The purpose of this report is to provide an introduction to the technology known as the Advanced Train Control System (ATCS), illustrate its functions and potential benefits in freight railroad applications, and provide a guide to quantifying the benefits and costs for railroads interested in...
High Speed Guided Ground Transportation (HSGGT) vehicle/guideway systems-both high speed rail (HSR) and magnetically levitated (Maglev)- are being considered for deployment in the United States. The Federal Railroad Administration (FRA) has the mission of ensuring the safety of such systems. To...
The Federal Railroad Administration's Railroad Safety Statistics Annual Report is intended as a resource for the FRA's safety partners. It is also intended as a general reference source for individuals and organizations with an interest in rail safety issues. Statistical data, tables, and chars are...
The Federal Railroad Administration's Railroad Safety Statistics - Annual Report is intended as a resource for the FRA's safety partners and other entities who play a primary role in promoting railroad safety. It is also intended as a general reference source for individuals and organizations with...
The Federal Railroad Administration (FRA) has sponsored a program to continue the validation of new techniques for testing and analysis that could be applied to the evaluation of the safety and track worthiness aspects of new freight car and suspension designs. The total program involves laboratory...
This paper discusses the safety challenges faced by railroads in the United States. It discusses and evaluates public policy dealing with trespassing, grade crossing collisions, occupational injuries, and operational accidents. The primary conclusion is that the government oversight body, the...
All rear-end train marker lights until recently were incandescent bulbs of almost identical design. With the advent of cabooseless trains and battery-powered end- of-train devices, new technologies using low-power LED and xenon flash tube lights were developed. Because of uncertainties in off-axis...
In response to a request by the Federal Railroad Administration (FRA), personnel of the National Bureau of Standards (NBS) and of the FRA visited the site of this accident. The purpose of this visit was twofold. First, to make observations that could be useful in studies of the properties and...
