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.
Methodology for Initial Assessment of Spectrum Requirements and Required Numbers of Base Stations in a Multi-railroad, Dense Traffic Area
AUTHOR: Schweitzer, Helmut L., Southern California Regional Rail Authority (SCRRA) OFFICE: RPD REPORT NUMBER: SUBJECT: Positive Train Control KEYWORDS: Spectrum; Radio Frequency Design; 220MHz RF Network; ABSTRACT: This report is intended to provide a methodology for performing an initial assessment of spectrum requirements related to deployment of a 220 MHz RF network for handling of Positive Train Control (PTC) messaging in a multi-railroad, dense traffic area. It also identifies how to determine the number of radio base stations required to support the projected messaging load in a territory. The radio network is intended to serve the needs of the PTC systems being deployed concurrently by multiple railroads in accordance with the requirements of the Rail Safety Improvement Act (RSIA) of 2008, and the corresponding implementing rules promulgated by the FRA. The methodologies explored and documented during the performance of this work is intended to assist other railroad entities with their deployment strategies as they develop their own PTC radio network deployment strategies for multi-railroads in dense urban areas.
