A thousand kilometres of above-ground facilities, a thousand kilometres of electric line and a thousand kilometres of moving parts to move 15 million people.... I've done linear projects for 25 years. I think it's fair to assume that the estimates you have are probably not adequate anymore, but I won't commit to any further numbers.
One of the things we want is for this process to be competitive. We want the private sector to not only help us but to remain competitive and to compete with one another. We'll be in a position to provide better numbers in a few years' time.
