From your link: The Hawaii Convention Center cost $350 million to build originally payed with bonds then refinanced, & Hawaii taxpayers will eventually end up paying $767 MILLION in principal & interest just for the original construction cost of the center.  Add the $10 million in yearly operating cost FOREVER for the center & the net loss of close to $5 million per year.  Financing the Oahu train the same way as the convention center using bonds or whatever so if the train ends up costing $15 BILLION, after paying interest payments, Oahu taxpayers might end up with a $30 BILLION dollar price tag for the train & probably close to a 1/4 BILLION maintenance cost FOREVER (about $100 million to HECO to pay just for electricity used by the trains, $125 million to pay for train maintenance & at least $25 million to pay for HECO for maintenance of the new fossil fuel electrical generator and infrastructure that has to be built to power the train. (Add $200 MILLION to build the power plant)
