I would say there are multiple layers of defence and response.
To Jim's point, the conductors are trained in haz-mat response and haz-mat handling. We have haz-mat specialists across the property that are there immediately. They're on call 24-7 to at least counsel and coach those who are on the ground. As you go up through the organization to the mechanical officers, to the train masters, all of those individuals have had training, and we're in the process of providing additional training.
As far as response time is concerned, it's immediate. The degree of response escalates as time goes on and gets stronger and stronger. It is an area that we feel is very strong. Even to that point, we've been in collaboration with CN prior to Lac-Mégantic, to decrease our response time, to increase our ability, sharing each other's resources, sharing each other's employees, sharing each other's knowledge, and our supplies in the event of a haz-mat accident.
