I'm happy to give you my views.
We know that the railways are heavily capital intensive, with 20% of the revenues going back into the system, meaning the equipment, track, and rolling stock. A lot of it, to be honest with you, is going into positive train control right now. We're seeing legislation happening in California to deal with this in the U.S. by 2015. They're going to have to make sure that components are talking with each other electronically to make sure it's as safe as possible for people and dangerous goods.
We'll probably see something similar to that investment happening in Canada. However, the railways are always expanding. As soon as they were deregulated and were able to invest on their own, we saw a huge expansion in rail lines. We saw increased capacity.
Working with government, with all the gateways, has been a phenomenal success. I'm talking about Halifax, Montreal, Prince Rupert, Vancouver, and others. There's always going to be that large, heavy investment in infrastructure. We have to make sure that we're working closely with government for the level crossings and the rights-of-way. If we get faster and faster and more efficient at this, there are going to be some implications for more investments for dark territory or cold weather hazards to make sure that we can calculate as best we can.
We produce the software. We produce this technology to help the railways. The suppliers that do this get to tell their message about how good they are in this area, but at the end of the day we're working with them to produce this technology. We don't see a decline in that investment. If anything, we see that if we do rebound, we need to position ourselves to capture a lot of that market, because we're saving a lot of time from the port in Los Angeles. We know it's just a disaster down there, and we can offer a competitive advantage.
