In fact, we encourage negotiation on everything in rail, but the long-haul interswitching provision is that if they cannot come to an agreement, then they go to the agency. It's the agency that actually sets the rate for the portion of the route where the product has to be carried to the interchange.
We've made the process quite efficient so that they would get a decision within 30 days. The rate would be based on comparable traffic moving in similar circumstances.
