The normal schedule of conferences and specialist technical sessions is as follows:
International Conferences -- every four years. These conferences will be hosted by one of the members in their country and will incorporate a program that includes the full spectrum of heavy haul subjects. Technical tours are scheduled before and after the meetings. Normally the conference and tours will cover a period of five days.
Specialist Technical Session (STS) - every four years and scheduled to fall in between the International Conferences (two years before and after). These are smaller conferences focused on critical issues of heavy haul operations. For example, in 1999 in Moscow, Russia a STS meeting was held on the subject of Wheel/Rail Issues of heavy haul railroads.
