I do want to come back to the point about economics, because there are challenges with the economics of rail in New Zealand, and we need to be upfront and clear about those challenges. New Zealand is a long, thin country with a small population base, and rail makes sense to transport quite a few goods—bulky goods, logs, other goods—and in the golden triangle of Waikato and Auckland and Tauranga, it makes a big contribution. Down the West Coast, as Maureen Pugh would tell me, there's a real role for rail. But we need to be pretty clear-eyed, I think, about the challenges that rail presents in other parts of the country, and I want to come back to those comments. So we need to be realistic. But rail is very important, particularly in our metro centres.
