I can comment on that.
Mr. Easter, what you're referring to is a process that actually was abandoned about 12 years ago. It was done basically in collaboration between the grain companies and the Canadian Wheat Board. They felt that keeping track of it was unfairly penalizing some groups, and it wasn't to the advantage of the actual sale of the grain. It was actually confounding the railway operations. They chose to abandon it roughly 12 or 13 years ago.
The system that was brought into place in behind that saw a more direct method of moving cars into position. What resulted from that was a far, far more efficient use of the railway equipment than what was used under that previous system.
