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.
Single Passenger Rail Car Impact Test Volume II: Summary of Occupant Protection Program
AUTHOR: Caroline VanIngen-Dunn OFFICE: RPD REPORT NUMBER: DOT/FRA/ORD-00/02.2 ABSTRACT: A test in which a single rail passenger car was crashed into a fixed wall at 35 mph was conducted at the Transportation Technology Center on November 16, 1999. The car was instrumented to measure (1) the deformations of critical structural elements, (2) the vertical, lateral, and longitudinal deceleration of the carbody and trucks, and (3) displacements of suspension systems. The objective of the interior tests was to determine the corresponding level of occupant safety for that impact scenario. Several interior configurations were tested with the appropriate data acquisition technology and quantified occupant injury parameters and seat strength characteristics. The car was equipped with anthropomorphic test devices (ATDs) in the following three arrangements: (1) Forward-facing unrestrained occupants seated in rows, compartmentalized by the forward seat in order to limit the motions of the occupants; (2) Forward-facing restrained occupants with lap and shoulder belts; (3) Rear-facing unrestrained occupants. The principal goal of this full-scale rail car impact test and the overall test program was to obtain scientific data that define a realistic rail car crash pulse, structural response, and corresponding level of occupant safety.
