I don't believe that there necessarily would be a direct impact, let's say, to the cost of passenger rail, but there would certainly be more traffic on the lines, and that can create delays and other impacts.
Really, what we would be doing, if this were to come to pass and you ceased using Line 5 and put in these alternative methods, is just moving from a very low-risk, very cost-effective and low-emission means of moving a product to one that carries a lot more consequences.
