One of the things I'd like to make clear is that the work that's going on is very focused on ensuring we have a safe protocol for handling the crude oil. It was noted that there is a variety of different kinds of crude oil, and the ones that are the most volatile are the ones that need to have the first access to modern transport capabilities. The plans of this working group are very much focused on ensuring a safe transition away from the old legacy cars that are safe in service for certain kinds of product, toward the transition to the new cars over the shorter period of three to five years, or one to five years, or whatever. The work of that committee has been very much focused on trying to ensure there will be a safe transition to that product handling.
