As I said in my remarks, I believe the system is one of many pieces of the puzzle. I believe the railways have a strong role to play there and have made a strong contribution. As I mentioned, we have invested in our physical plant, we've invested in locomotives, we have hired people. We are in the business of transporting products. The grain companies and the country elevators have rationalized over the years. They have made changes to their network. If there are no elevators on a grain line and no grain coming to an elevator, other business decisions get made.
So I feel quite confident that we have done a lot of very positive things over the years. Again, I also believe it takes every part of the chain to work together to continue to improve.
