I'm not aware that we're doing that, but you have to look at things from a logistics point of view. These railways were built throughout Canada, and cities grew up along the railways. They grew up there because that's where their industries are.
For instance, if you want to route everything around the city of Montreal, but the goods are going to the port in Montreal, you're going to end up with a rail line—I don't know—way north or way south of Montreal, and then how are you going to get the goods in? You're going to have to truck them in.
I think that sometimes easy solutions are not the way to go. You have to look at the network. You have to look at the realities on the ground, and you have to bring the risks down within the system that's there.
