The way the railways operate their networks, rail service operates very much like a bus route operates. So what you're looking at are the needs of everybody along the route and you're trying to come up with a schedule and an approach to serve everybody's needs in an efficient way. From that optic, the arbitrator, in receiving a demand from a shipper, will look at what the shipper needs, considering what the railway service is on that route for all of the shippers on the route.
It's a factor they take into account. If the shipper is saying, “I absolutely need more for my business”, and makes a case for that, then the arbitrator has the discretion to respond to that.
