I wanted to go back to the issue of data, because it has come up a number of times in previous studies, including this one. Somebody in one of the earlier panels talked about the granularity of the data. In other words, what kind of detail is there in the data that would be helpful to shippers and in their negotiations with the rail companies?
Mr. Johnston, maybe you could speak to that. Data is one thing, but what kind of data? What do you really need to know that you would like to have, practically real time?
