It was really before 2007-08. We implemented what we call our scheduled or our precision railway. So we had a lot of insular focus on ourselves in managing our traffic patterns, how we were going to move and block and marshal the traffic from our hub-to-hub. I think what came out of the rail freight service review was that we were very good from hub to hub; it was just, as we've been talking about, the first mile, last mile, and the intricate connection to our customers, that needed work.
