Thank you very much, Mr. Chair.
Thank you very much for coming forward today and for your wealth of information.
One of the things on which I would like to have a little bit more discussion is the length of the cars. We understand that speed is definitely a mitigating factor here. Do you consider the length of the cars and the weight of the cars to be very significant factors, as well? If so, is there a level of importance? Is one more important than the other when it comes to the safety issues that are being discussed?
