I'll jump in first.
In terms of tripling between now and 2045, I haven't done the math on it. It seems a little aggressive. Long term, if you look at rail demand, it's something in the range of the GDP. There are clearly variances in crop production or the opening of a new mine, let's say for potash. We're not looking at something that's triple, but we certainly have to continue to invest. We have to continue to grow our network capacity, and we have to continue to improve our efficiency.
