I don't have the numbers here. Last year, the Railway Association of Canada put forward some numbers that were part of a memorandum of understanding between the railways and the federal government. The railways are already meeting Kyoto objectives, even in their existing operations. This is quite apart from what could be achieved if there were a substantial shift from a fossil fuel system to an electrified one. We're behind the rest of the world in rail electrification, and we know there is renewed interest in this matter in Ontario and Quebec. The potential benefits are significant, but I can't give you the numbers right now. Of course, you'd have to reallocate the routes and schedules to rebalance the traffic on the system.
