He definitely intends to replace the tanker cars. As far as transition is concerned, it will take a couple of years to be able to do it. An exact timeframe we have not come to yet, but we are in the process of developing that.
A key point to remember, though, is that the tanker cars at CP haul diesel fuel. Diesel fuel is dangerous, and I'm not suggesting it's not, but it's low risk relative to other items, and it's the same fuel that our locomotives burn. It's something we're seized with, we're concerned with. But I just want to make that point known: that is the only thing that CP hauls in those cars.
