Well, I agree with Mark's comment in terms of a key measurement element that we can add to that. As I said, once the cars are filled and ready for pickup, then we need to continue to monitor, as we are now, looking at transit time by different corridors.
Our supply chain, especially in pulse and special crops, is very complicated. It's a move that involves steamship lines, it involves container lines, it involves transloading facilities at port position. When we have problems—and I like to use the example of a comparison to air traffic. It's like trying to make connections through multiple airports. When you have a problem early on in the voyage, it has ripple effects on down the line. We want to be measuring all of these elements together. I'm looking at vessel rollovers of containers. We want to be looking at cancellation of container bookings on through.
The key theme is that the focus shouldn't be on any one particular element. The railways clearly play a key role because of the movement to port. But our focus is not about simply looking at one element; it's about looking at all of these elements integrated together. I think this is the challenge.
The question the committee is asking is about the role of the federal government. Our view is that the federal government can play a very important role in monitoring system performance so that we're continuing to focus on becoming better.
