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.
Development of Conventional Passenger Cab Car End Structure Designs for Full Scale Testing
AUTHOR: Ronald Mayville (Mayville andAssoc.), RichardStringfellow (TIAX), and Eloy Martinez (Volpe) OFFICE: RPD REPORT NUMBER: DOT/FRA/ORD-06/20 KEYWORDS: Transportation, safety, crashworthiness, passenger rail vehicles, cab car end structure ABSTRACT: The Volpe Center is supporting the Federal Railroad Administration’s full-scale testingprogram to understand and improve rail
vehicle crashworthiness. The objective of one of the sets of tests in this programis determining thebehavior of cab car end
structures in simulated grade crossing collisions. The project described in this report supported these tests bydeveloping ready-to-
fabricate designs for the endsof passenger cars to represent a State-of-the-Art (SOA) and a 1990s cab cardesign, bothof which
are primarily strength-based designs. Thereport includes a description ofprior research on cab car crashworthiness, the
requirements for the designs, the designs themselves and the analyses used to demonstrate that the designs meet the requirements.
Also included is a comparison between strains measuredfrom quasi-static load tests and from finite element analyses. The results
of the project show that the SOA endframe provides substantially greater strength and energy absorption capability than the 1990s
designwith little penalty in weight.
