I'll deal generally with crossings and how crossings are managed in Canada. As you've heard, there's a new regulation that came into place last year on grade crossings. We participated in the making of that regulation, and I'll cut to the chase here. We are compliant with the regulatory requirements, but we believe they fell short. The reason they fell short is that we're not looking at a corridor when we're talking about grade crossings. We're talking about single crossings.
One of the problems we have here is that we're upgrading, or being asked to upgrade, every single crossing without asking the question of whether the crossing needs to be there to begin with. Is it safe? Why do we have it? In our view we should look at the corridor, identify the safe locations to cross, make them as safe as we possibly can, and close the rest. That's the approach we believe should be taken. That's difficult to achieve in our current regulatory environment.
