I have just a quick answer to that one on whether we should change it or not. In adding one-sixteenth to the thickness of material for the unjacketed car, you are adding about 9,000 to 10,000 pounds to that car. Don't forget the gross freight load. I talked about it. Your top load is 286,000 pounds. If you put 10,000 pounds there, you give up 10,000 pounds on your capacity. On the jacketed, insulated car it's a little bit less; it's 7,000 to 8,000 pounds, so you are giving up 8,000 pounds of your loading capacity.
