As I said, Metrolinx embraces the whole notion of enhanced safety. We recruit APTA, the American Passenger Transportation Association, to come up and interrogate our systems for the appropriate levels of safety. They create a report, to which we respond. We do that and cycle it every three to four years.
In the last two weeks, we started a program about rail safety, sponsored by the Railway Association of Canada. The association does interviews top to bottom in the organization to get a sense of the safety culture. Then they come through with recommendations on things that should be done differently.
We are in the planning stages of rapid growth for GO Transit, where our services will increase dramatically. An assumption of this large program is enhanced train control, which is taking the positive train control that is being put in place in the United States and increasing it even further. Enhanced train control takes a certain amount of human intervention out of train management and train operation. We think that with the higher frequencies we're expected to deliver, that is a basic condition that we have to include.
