As I indicated in my presentation, standards are developed through the involvement of industry manufacturers, regulators, government, and interest groups.
It was determined that the DOT-111 tank car could be used and is an appropriate means of containment to transport certain types of dangerous goods, like petroleum crude. We are always looking at and improving the safety features of a means of containment to make sure every dangerous good is transported safely.
As I said, we will publish the next standard quite soon. It will help with the safer transport of petroleum crude through Canada by improving certain safety aspects, such as thicker steel, protective head shields, and certain types of components that will make it better.
But we're always looking at ways of improving and of making sure dangerous goods are transported safely.
