I can only speak to the maintenance issue because that's where we went through a fairly extensive study. It was not difficult to get figures from those that carry out maintenance on similar kinds of equipment throughout North America. In that case, I think we were able to come up with a number that, quite frankly, is significantly lower than the costs being charged in the revenue gap.
I think the point we were trying to make in this submission as well is in our recommendation number six. What it costs the railway is one issue; the second issue is that we should have a mechanism whereby if the private sector shops can do it for a lower cost, it should be relatively easy for that to happen.
I don't think the legislation as it currently exists and the practices by Transport Canada historically have allowed those private shops to actually compete for the work.
