Yes. I guess part of what we looked at is the Kroeger study that was done in 1999 and 2000. At the end of it, the group recommended that a review be undertaken of “productivity gains and sharing of these gains...at a point in time when it is felt that most of the overall changes to the System...had likely occurred”.
We believe that there have been a large number of changes within the system, such as the ability for railways to group lots of cars together. We're seeing 110-unit train cars that we never saw in 2000. We're seeing efficiencies in locomotive diesel usage and labour. We're not pulling cabooses around the country anymore. These efficiencies have occurred. The Kroeger report said that we should have a review of those rates after efficiencies occurred.
