I took at look, in the last few days, at how long some of these unit oil trains are. Typically, when we have an accident, they seem to be about 100 cars long, according to the data we have. In fact, the oil trains don't seem to be abnormally long compared to some of the other trains that the railroads put together.
With respect to capacity, the new cars have less capacity than the old ones because there's extra steel and extra insulation, so they actually hold a little bit less oil in each tank car.
