Since 1976, we have led the effort to disseminate technical knowledge and best practice in the heavy haul industry.
Our Mission
The IHHA is dedicated to the pursuit of excellence in heavy haul railway operations, engineering, maintenance, and technology. It strives to accomplish this mission through the acquisition of knowledge relevant to this goal by sponsoring and organizing international and regional conferences, specialist technical sessions and specialist seminars; by commissioning guideline manuals, by preparing and distributing conference proceedings and technical documentation and by related activities as recommended by the Board of Directors. The IHHA engages in a continual process of adaptation to ensure it satisfies the demands of state-of-the-art technical information that is relevant in a changing and developing industry.
Our ORIGIN
At a crucial moment in 1975-76, the inspiration for establishing the Association arose from groundbreaking advancements at the Melbourne Research Laboratories of Broken Hill Properties Co Ltd (BHP), focused on the Mt Newman Mining and Hamersley Iron railways in the Pilbara region of Western Australia.
The vision behind this work was to share the valuable insights gained in that research with heavy haul railways worldwide. Embarking on this journey, we discovered that global railways faced similar challenges. This shared recognition led to meaningful dialogues, seeking collective solutions. Thus began a global conversation, inviting railways transporting commodities like coal, grain, iron ore, and others to participate actively, giving rise to the IHHA.
“The IHHA has led the way in developing quality materials for railway professionals.”
