The railway will see what the shipper is asking for and have the opportunity to provide its own view of what service should be required, and then the arbitrator will make a decision.
There will also be in the process an opportunity for the two sides to question each other. The railway would be able in that kind of a situation to say, we've been serving you at this particular level for the last 10 years, and we don't understand you're now saying you need something different. It seems to work. That discussion could take place, and then the arbitrator would in the end, balancing everything, consider what makes sense.
