Basically the two mills I'm talking about, Longlac and Nakina, and also McKenzie and Hudson, are on the main line, and the main-line trains are already maxed out when they leave Toronto or when they're coming to Toronto, so they don't have the facility to pick up extra cars. If they're running three maxed-out trains a day, they don't want to incorporate the fourth one if it's not going to be 100% utilized at the same time.
So we've talked to them, and we say they're not going to grow their business if they don't start the fourth train, because we have cars they can pick up. And that's where the debate is. They're trying to maximize their assets to the point where—their term is “velocity”—it makes it totally efficient from their point of view, but totally inefficient for the people who are on their services.
If they're getting paid more for petrochemicals or more for other products than they are for lumber, then we sort of fall by the wayside, because they're trying to service those other industries where they can charge more because they are a commodity-of-the-time, such as oil and gas and stuff like that.
