Education Partners

The Railway Supply Institute (RSI) has a long standing relationship with the Coordinated Mechanical Associations (CMA). RSI supports and coordinates their technical and educational presentations and programs around our trade shows including Railway Interchange and the annual RSI Education & Expo Conference.

There are currently five organizations that comprise the Coordinated Mechanical Associations. See below for more information on these organizations.

The Air Brake Association (ABA), established in 1893, helps guide the industry on items relating to air brakes on freight cars, passenger cars and locomotives. A dedicated group, the ABA has only canceled their meetings during World War I and World War II.  In 2008, the ABA celebrated its 100th convention and proceedings book.

The International Association of Railway Operating Officers (IAROO) provides members with pertinent operating and technical information that will allow them to provide superior railroad management for the future. The association was founded in 1892 and is the oldest professional railroad association of the coordinated group. Speakers are recognized as among the top experts in their respective fields.  We offer three technical manuals for purchase by members and the general public.

The League of Railway Women (LRW) is dedicated to providing women with the opportunity to gain a broader understanding of the railroad business and achieve personal and professional goals at every career level. Representing a dynamic and diverse group of women from across the industry, LRIW provides leadership opportunities, educational sessions, and networking events throughout the year.

The Locomotive Maintenance Officers Association (LMOA) consists of railroad industry officers involved with the repair and maintenance of locomotives and shop related equipment. LMOA works to improve the skill, knowledge and capability of its members through continuing education and to exchange maintenance experiences and information.

The Railcar Technical Services Association (RTSA) is dedicated to provide training and value added forums relating to railcar maintenance needs in the areas of new technology, practical experience and best practices. The objective of RTSA is to bring together individuals interested in freight car maintenance matters.
