Flutterby™! : Cheapest != Cheapest

When it comes to mass transit, the lowest bidder doesn't seem to equate to the lowest cost implementation. Bloomberg discusses how the NYC Second Avenue line cost $5B and how the proposed Northeast corridor high speed rail will cost more than Japan's underground mag-lev. I've been seeing the same results with RTD FasTracks which was originally supposed to extend to Longmont this decade but now gives a best possible scenario of 2035 with significant tax increases.
