Federal Railroad Association (FRA)

The Federal Railroad Administration (FRA) was created by the Department of Transportation Act of 1966. It is one of ten agencies within the U.S. Department of Transportation concerned with intermodal transportation. FRA’s mission is to enable the safe, reliable, and efficient movement of people and goods for a strong America, now and in the future. 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.


GoRail unites rail stakeholders with community leaders and the public in support of rail solutions to tomorrow’s transportation challenges. GoRail believes that every additional ton of freight moving by rail instead of over our congested highways means more jobs and a stronger economy, less pollution and cleaner skies, and greater fuel efficiency and clearer roads ahead. GoRail was founded on the principle that “all politics is local” and that direct input from constituents is the best way to communicate with Members of Congress.

Private Car Ownership Committee (PCOC)

The Private Car Owner Committee (PCOC) reports to the Associate Advisory Board. The PCOC provides a forum for private car owners to discuss matters of common concern and will serve as a mechanism to assure private car owners’ input is considered in proposed rule changes put forth by AAR technical committees.

Essentially, the committee will appoint a representative to provide input in the cost-benefit analysis of new or amended rules affecting the interchange of rail cars proposed by a committee where no private car owner associate member is currently seated.

Railroad Safety Advisory Committee (RSAC)

RSAC was established to develop new regulatory standards, through a collaborative process, with all segments of the rail community working together to fashion mutually satisfactory solutions on safety regulatory issues. The Committee shall seek agreement on the facts and data underlying any real or perceived safety problems; identify cost-effective solutions based on the agreed-upon facts; and identify regulatory options where necessary to implement those solutions. In determining whether regulations are necessary, the Committee shall take into account section 1(a) of Executive Order 12866 (Regulatory Planning and Review).

The RSAC will provide advice and recommendations to the Federal Railroad Administration (FRA) regarding the development of the railroad safety regulatory program, including issuance of new regulations, review and revision of existing regulations, and identification of non-regulatory alternatives for the improvement of railroad safety. Of course, the RSAC's own resource limitations will not permit FRA to refer every safety regulatory task to the RSAC. Moreover, on occasion, the need to address a safety issue in an expedited way will preclude such a referral.

Railway Supply Institute Tank Car Committee (RSITCC)

The RSI Committee on Tank Cars (RSICTC) addresses issues of importance to tank car builders and owners and regularly reviews tank car requirements through its membership on the Association of American Railroads Tank Car Committee.

RSICTC remains at the forefront of the latest research to improve tank car safety and represents tank car manufacturers in federal, legislative and regulatory matters.
