Let me answer the last question first. I don't think it's attributable to luck. A great deal of effort has been put into the whole issue of dangerous goods. We met with the Canadian Chemical Producers and talked to them about their procedures. They had a great deal of pride in what they were doing to reduce problems. We were impressed by the effort being put into the transportation of dangerous goods.
To go back to your first question, if you go to page 69, there's a quote in there from Faye Ackermans, of CP. The first sentence says it all: “[Changing culture] is a journey; the progress we have made is still fragile.” I don't think you ever achieve perfection in trying to create a safety culture.
There's also, in this particular section, an effort made by an individual to define what happens. On page 73, there's an interesting evaluation tool for measuring safety culture. There are five types of safety cultures that companies have. That particular example tries to describe what this culture is made up of in the various companies.
