I think the current revenue cap is a pretty flexible policy tool. We're worried about natural monopolies in railways, so we want to regulate them somewhat and monitor their costs, because they have the ability to price pretty harshly against competition. They could basically price against trucking as their only major competition, so it could really get out of hand. However, when they now have the flexibility of the revenue cap to charge for specific services that consumers want or to manage things in a certain way, I think that's actually a pretty good piece of regulation.
For that reason, I don't know that rail transportation is as serious a problem as other people think it is.
