Our interpretation of that would be the fact that for us, again, because of our isolation in certain parts on the rail, the biggest challenge is to get people and product to the spill, accident, or whatever incident it might be. So, we're recommending, particularly with volatile products—crude oil, for example—that we would have a response car attached. It would run directly behind the engine and carry all the retardants—all the products we would need if there were an incident.
