Thank you.
I was just going to add two quick points to what's been said, because it's an important question. I think they both relate to the notion that we have a complex supply chain, so it wasn't—and rail is the easiest piece of it to target and look at and try to poke into, because there's a lot more opportunity, but we have other players in the supply chain. I'm thinking of people like ports and terminals. Part of what happened over the last several years was an outreach there, and we've collaborated with them a lot more efficiently and together we've come up with improvements in terms of the supply chain. So it hasn't just been rail, but part of it was that relationship-building.
The other thing that happened, I think significantly, is that we're starting.... We've been making a plea for some time now to give us more visibility in terms of the traffic that you as a customer or groups of customers want to deliver to us. When you do that, watch our service improve. The two are inextricably linked.
Those two things I spoke about have started to happen over the last four or five years. I think they're a big reason why, collectively, the supply chain is performing better.
