On the issue of grade separation, you're quite right that one of the things that in fact has helped the Asia-Pacific gateway to de-bottleneck.... People previously had to wait half an hour while a very long train went by, or the train had to slow down and let rush hour traffic go through. Grade crossings did represent a significant bottleneck in the Asia-Pacific gateway, particularly in the greater Vancouver area. Some significant projects were put through to provide grade separation.
Grade separation can be important in de-bottlenecking so that nobody is stopped and everything moves smoothly, but there's another aspect of it as well that recently came to light, as you know, with the tragic event that occurred in south Ottawa where a VIA train struck a bus and there were, as I recall, six fatalities. The TSB examined it. One of the TSB recommendations to us at Transport Canada would be to look at perhaps putting together a set of guidelines that would dictate from a safety point of view when it would be appropriate to have grade separation from a safety point of view. That is something we just started recently to look at.
Of course, grade separation implies sometimes considerable costs, but we are looking at it from a safety point of view in the sense of putting out guidelines that could be used by municipalities and others.
