I think it should be said as well that there is a differentiation between railways and the railway manufacturers. We all hear that the railways are making a lot of money now. If you'd bought into shares of CP and CN, you're doing quite well. It's the manufacturing sector for railway suppliers that we're concerned about.
There are 500 companies now that either manufacture or supply goods to the railways, and as we see, Bell Canada and Telus are new members, with their GPS systems and RFIDs. It's very high-tech now.
We have to make sure that when there's capacity or when we're trying to meet capacity and demand with the Pacific gateway or urban transits, the companies that are building it are healthy here in Canada and there is a healthy economic incentive to manufacture and supply these goods, as opposed to going elsewhere internationally.
