We think there should be. The example of the United States is that Congress took that responsibility by enacting legislation that there would be positive train control. Now there are some logistical problems in when it will actually be completely rolled out, but the railways are already investing heavily there because they have to.
In the rest of the world, those kinds of investments have already been made. Positive train control in the United States actually goes back to the 1920s, when it was first introduced. Yet in Canada, with the single exception I mentioned of the O-Train in Ottawa, a passenger railway, we don't have it on any of our federally regulated rail lines that carry passenger traffic.
So yes, federal government action is required there. We're moving much too slowly in the wait-and-see attitude to see how it works in the United States after the railways there have made these investments, including Canadian-owned railways. CN and CP are making those investments in the U.S. portions of their network.
I think that's something the government must do.
