We haven't tabled this, but we certainly could. When Lac-Mégantic happened, 80% of the tank cars in service for crude oil were DOT-111 or the CPC-1232 unjacketed, which we have called the least crash-resistant or the less robust tank cars. As of today, virtually all of those have been removed from service in North America, and now 80% of the cars are of a much higher quality. We are still looking at, and will continue to look at, when an accident happens, what happens to the cars involved.
In the most recent accident, only six or seven—we're not quite sure yet of the number—cars out of 37 that derailed were damaged. In Lac-Mégantic about 65 cars derailed and 63 were damaged in the accident. There's clearly a difference in the containment capability, but it will take more accidents for us to be able to have good numbers.
