The Federal Railroad Administration (FRA) was created by the Department ofTransportation Act of 1966. It is one of ten agencies within the U.S. Department ofTransportation concerned with intermodal transportation. FRA promotes safe,environmentally sound, successful railroad transportation to meet the needs of all customers today and tomorrow.
FRA's Office of Railroad Safety promotes and regulates safety throughout the Nation's railroad industry. The office executes its regulatory and inspection responsibilities through a diverse staff of railroad safety experts.
The Federal Railroad Administration is responsible for working with stakeholders to develop cohesive goals and policies for maintaining and improving the U.S. freight and passenger rail networks. This section covers various efforts across America and the world in helping to deliver safe, reliable, and efficient rail transportation.
FRA Research & Development (R&D) projects contribute to the FRA's safety regulatory processes, to railroad suppliers, to railroads involved in the transportation of freight, intercity passengers, commuters, and to railroad employees and their labor organizations.
In this section, we provide descriptions and comprehensive, official sources for FRA's regulations (also called rules), selected legislation, as well as policy and guidance documents. Additionally, you will find current topics of high interest or significant impact to Congress, railroads, employees, labor, public interest groups and other stakeholders.
FRA supports passenger and freight railroading through a variety of competitive grant, dedicated grant, and loan programs to develop safety improvements, relieve congestion, and encourage the expansion and upgrade of passenger and freight rail infrastructure and services. FRA also provides training and technical assistance to grantees and stakeholders.
Passenger Rail Train-to-Train Impact Test Volume II: Summary of Occupant Protection Program
AUTHOR: Caroline VanIngen-Dunn OFFICE: RPD REPORT NUMBER: DOT/FRA/ORD-03/17.II KEYWORDS: Passenger Rail Train-to-Train Impact Test Volume II: Summary of Occupant Protection Program ABSTRACT: On January 31, 2002, a train-to-train collision test was conducted involving a cab-car-led consist with three coach cars, all of
conventional design, and a trailing locomotive traveling at 30 mph into a stationary locomotive coupled with two ballasted freight
cars. The objective of this test was to determine the corresponding level of occupant safety for that impact scenario. In this test,
the two leading cars and locomotive were equipped with instrumented anthropomorphic test devices (ATDs) in four interior
seating arrangements as follows: 1. Two forward-facing M-style seats, each with three unrestrained ATDs in the back-row seat (one set in the lead cab car, one in the trailing car); 2. Two forward-facing intercity seats with two unrestrained ATDs in the back-row seat and two restrained ATDs in the front-row seat that was modified with seat belts and energy absorbing devices; 3. One unrestrained ATD in a locomotive operator seat. The principal goal of this full-scale rail car and locomotive test and the overall test program was to obtain scientific data to define a realistic rail car crash pulse, structural response, and corresponding level of occupant safety.
