I think that's an issue that is in front of all of us that we need to try to figure out. We do have an issue with the hopper cars. It was government that had invested in them in a significant way in the last round. The cars are coming to the end of their useful lifespans. There is a significant problem with the maximum revenue entitlement and how it treats investments, which is what we refer to as the free rider problem, meaning that if CN goes and buys 1,000 new hopper cars, the formula by definition gives 50% of the benefit of that investment to my competitor.
I think there's work that needs to be done with modernizing the maximum revenue entitlement if we hope to have a situation where either railway companies or customers have an incentive to reinvest in the fleet.
