Speaking for myself only, the primary problem with the HART rail project is that it's long been treated by many of its primary advocates as a cash cow. While it's already progressed too far to call a complete halt to it, nevertheless something must be done to rein in the project's escalating costs. In that regard, Wilson's idea deserves serious consideration by city officials. We should not allow the same people who drove us down this fiscal cul-de-sac to dismiss it in their effort to return to business as usual. Bringing the train town to street level after Middle Street and converting the project to light rail will not only save us a lot of money, but will also offer the city future opportunities for a relatively quick and economical expansion of the system eastward to UH, Waikiki and Kahala Mall, as may be desired and / or needed. And that's something which won't be easily accomplished, if HART continues to insist upon an elevated heavy rail system terminating at Ala Moana Center.
