I wouldn't expect the TBM will be re-usable if it's built to dig one large tunnel, so it's a moot point on who buys it. It doesn't take much reading between the lines to see the tunnelling costs are going way over budget, hence the scramble to find the cheapest way to do it, but there really is no cheap way to tunnel through downtown. So watch for a request to increase the budget (hello city taxpayers if 6 billion is the number) or say goodbye to a couple of stations in a round of cost cutting.
