Certainly that's our experience in terms of the freight railways. The decision is already made that they're going to implement an operational change, whether they want to leave westward trains out of Winnipeg, for instance, or give them about seven miles so that they're braking and come back up to 100%, but those decisions have already been made. Operationally then they just send out the crew, their team, to conduct the risk assessment and the risk assessment once it's completed gets thrown in a file and off we move.
In the risk assessment process, as Jerry said in his opening comments, there's never been one in my experience where the railways have done the risk assessment and said, “My goodness, this is way too dangerous. We're not doing it”. They simply don't do it. It doesn't matter whether it's even in the face of prior events, all the risk assessment does is just provide a bit of a lens and they say, “Well, let's try to do these items to mitigate the risk.”
