I think Kevin might want to jump in on this one as well. In the States, for example, you can trade whole trains. For example, if one of Kevin's members really needed 100 cars and he just couldn't get the cars here, he would go to another company and say, “Look, why don't I give you $3 or $4 per tonne and I'll take your train that's almost in Vancouver and just send it over to my terminal?”
You can see a lot more of that sort of stuff happening in the American system, where you can buy and sell that as more of a commodity. We don't see that in Canada. Again, we're regulated in such a way that doesn't happen. I think that's one possible suggestion of what could be done.
The other one would be that maybe there's a financial incentive where instead of the railways offering $4 per tonne for loading a unit train, they'd offer $5 per tonne if you could wait an extra three weeks when we're not as busy with our engines and crews. I think financial incentives are always a better way to go than a stick, if at all possible, to help level off the humps. There are several things that we haven't looked at, even in Canada, to help do that.
Kevin, would you add to that?
