Well, to follow that further, if you were to increase the thickness of the hull of a particular car, you could lower the capacity to carry a particular dangerous good, for example, to offset the increase in thickness. That could lengthen the train as well, though, could it not? If someone is committed to carrying a certain capacity of a dangerous good, they could presumably lengthen a train. If the choice were to have a thicker hull with less capacity, it could lengthen the train, I guess is what I'm trying to say. Is that fair enough?
