That is perhaps one of the factors. In the case of the Canadian railways now that are aware of this recommendation, because they operate across the border and because there will be positive train control being implemented in the U.S. in the next few years, they want to make sure that whatever system they're going to implement in Canada is going to be compatible since they cross the border. That may explain, to some extent, the timing of their investments. This is a significant technological investment. We still believe solutions are available. Some companies in Canada may be experimenting with some of those now. The longer we wait, the more risk there will be in the system.
