That's a good question. We go through fleet-sizing exercises on a continuous basis. We do a multi-year plan. We work with our commercial people in terms of what the demand is. We work with the operations people on what the cycles are going to be, and then we come up with a plan.
What we're seeing right now is largely an improvement in cycle time. Demand, especially on grain, can be highly variable. We have a tendency to think of growth all the time in a lot industries, but in grain, the volumes we're seeing now may or may not be larger or smaller than in the future.
So it's really an exercise. I think this is a key thing. You have to have this process and this flexibility to be able to address demand as it comes, whether it's up or when it's down.
