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 I: Overview and Selected Results US Department of Transportation
AUTHOR: Tyrell, David OFFICE: RPD REPORT NUMBER: DOT/FRA/ORD-03/17.I KEYWORDS: Passenger Rail Train-to-Train Impact Test Volume I: Overview and Selected Results US Department of Transportation ABSTRACT: This report describes the results of the train-to-train impact test conducted at the Federal Railroad Administration’s
Transportation Technology Center in Pueblo, Colorado on January 31, 2002. In this test, a cab car-led train, initially
moving at 30 mph and consisting of a cab car, three coach cars, and a trailing locomotive, collided with a standing
locomotive-led train with two ballasted open-top hopper cars. The test included test dummies in the operator’s seat of
the impacted locomotive, and in the cab car and first coach car.
This test was the third of three tests intended to define the performance of current-design equipment in in-line
collisions. The objective this test was to observe the interaction of the colliding equipment and to measure the
environments experienced by the test dummies, as well as the responses of the test dummies.
During the train-to-train test, the cab car overrode the locomotive; the underframe of the cab car sustained
approximately 20 feet of crush and the first three coupled connections sawtooth buckled. The short hood of the
locomotive remained essentially intact, while there was approximately 12 inches of crush of the windshield center
post. The test measurements of the response of the trains compare closely with predictions made with lumpedparameter
