Yes, it was done with Alstom. We worked with a group of engineers. We worked as three groups: our own employees, the engineers from outside firms, and the suppliers.
We did the same thing for our new system, a system called iBus. We hired people who know the technology, and now we are bringing them to our system. We put the people together so that when they leave we will know how to run things and achieve the assets. Afterwards we can do it in-house. That is the way we're doing it. We're working with a lot of universities to accomplish some things with our employees.
