HOSTS

The International Heavy Haul Association (IHHA) is at the forefront of driving innovation and excellence in the world of heavy haul railway operations, engineering, maintenance, and technology. Since its founding in 1976, IHHA has remained committed to pushing the boundaries of the industry through cutting-edge knowledge exchange, delivering the latest technical advancements, and sharing best practices to meet the ever-evolving landscape of rail transportation.

The 2025 IHHA Conference, with the theme Inspiring Innovative and Resilient Railways, is set to be an exciting convergence of ideas, insights, and solutions. This global platform provides a unique opportunity for researchers, industry leaders, policy-makers, and innovators from around the world to share groundbreaking research, collaborate on transformative solutions, and forge new connections that will shape the future of rail transport.

The conference will be split into the following streams, covering a varied range of sub-topics:

• Sustainable innovation:
  Decarbonisation of rail | Alternate fuels | Resource efficiency | Circular economy | Sustainable innovation in heavy haul railway projects | Sustainability challenges and opportunities for heavy haul railways
• Vehicle track systems:
