The Australian Rail Industry Standards Organisation (ARISO) is seeking nominations from experts with experience in rolling stock dynamics and design and/or maintenance of suspension systems, to join a Development Group to review AS 7509 Rolling Stock – Dynamic Behaviour.
How will this help the rail industry?
