Yes, it's a nice problem to have. I think it shows the support for rail.
But just to answer your question specifically, I believe there's a lot more scope for electrifying commuter rail first, but of course those things require public investments. Part of the importance of looking at the rail industry and at the innovation and the technologies available, certainly from a public policy standpoint, is for people to understand that when we make those investments as a society, there are benefits that flow to all of society.
First of all, people will use the trains when they're built. If you talk to the general manager of GO Transit, he'll tell you that when he puts a new car on, within two weeks it's full, and the complaints start up again that there's no room. He has gone, in 10 years, from a capital budget of about $100 million to over a billion dollars in capital budget.
So when you build it, they will come. I think where you want to look for electrification to the extent possible, there are also a lot of challenges there with interchange and everything else, but that's probably the place to start.
