I guess there's a combination of things. In the last couple of years we've had crops that have been far beyond what anyone had forecast. At the same time, I know people say you know winter's going to happen, but the reality in railroading is that winter causes you to run short of trains, which means you have more trains in your capacity slots. You need more crews. You need more locomotives, and all of that has quite an impact on the network.
It's a difficult situation if someone wants you to try to maintain all of this additional capacity for these surges under a regulated rate structure.
