History

History Of The International Heavy Haul Association Inc.
By John G German,
Former Executive Director

The International Heavy Haul Association (IHHA) is a world wide non-governmental, scientific and technological association of heavy haul railways and their advocates. The IHHA is incorporated in the State of Missouri in the United States of America as a not-for-profit association.

Origin
Based upon the work done by the Melbourne Research Laboratories of the Broken Hill Properties Co Ltd (BHP) for the Mt Newman Mining and Hamersley Iron railways in the Pilbura region of Western Australia the idea sprang up in 1975-76 to disseminate the knowledge gained in that research program with other heavy haul railways of the world. After discussions with other countries it was determined that they were not alone in their concerns and problems. Therefore, they sent out invitations world-wide to those railways that were involved in using dedicated unit trains to haul such commodities as coal, grain, iron ore, etc.
