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.
Documentation of Deformation from Passenger Rail Two-Car Impact Test
AUTHOR: Robert A. MacNeill and Steven W. Kirkpatrick OFFICE: RPD REPORT NUMBER: DOT/FRA/ORD-03/08 KEYWORDS: Documentation of Deformation from Passenger Rail Two-Car Impact Test ABSTRACT: The Volpe Center has been conducting research into rail equipment crashworthiness in support of the Federal Railroad Administration’s (FRA) Office of Research and Development. As part of this research, full-scale crash tests of passenger cars have been performed. Subsequent detailed post-test examinations develop an improved understanding of the collapse mechanisms of the dominant structural elements as well as overall dynamic crash behavior. This knowledge can be used for interpreting test data, estimating energy dissipation during the test, developing detailed finite element models, and designing safer passenger cars.
This report documents a detailed post-test inspection performed on the lead car from a full-scale test featuring two coupled passenger coach cars impacting a fixed wall at 26 mph, which was conducted on April 4, 2000. Damages to primary structural members including the draft sill, side sills, and cant rails were documented including modes and magnitude of deformation. Other secondary structural components such as the superstructure skin, belt rails, and floor were also documented.
