The reality of it is for every 20 projects that any of our companies hear about, maybe one actually turns into a real project. A large part of what we do is talking to governments, different levels of government, and really trying to filter out which ones have the strong political will behind them, because that's the main determinant of whether a project goes forward or not, how much political decision-making has occurred and how much force there is to really put money behind it, fund the project and make it happen. Generally, there's a whole industry that does planning studies, Marshall Macklin Monaghan, IBI Group, Delcan, Hatchmont MacDonald. You can go to any one of these companies and they'll have dozens of studies for integrated transportation systems. That's their business.
Our business is much more limited. We'll come in, we'll join forces with the construction company, and we'll build something. We'll provide the rolling stock, the electrification. Generally, we're not even the operators. There's a whole industry that are operators and they do operations. They'll run the systems for you. We'll do maintenance. Generally, that's something we're very good at, because it's our equipment. But there are limitations to what we can do, as manufacturers.
