The train itself is made in Japan it seems. So tell the manufactures that HNL will not pay the for the next 30 or so years and to get the funding from the Japanese Gov. In the current economic state, Japan has given loans to many of its heavy machine manufacturing industry to export Japanese goods to other countries. The Japanese gov has limited choice. Take advantage. Its called being savvy. 
I think that the HNL gov are bad business people and lousy leaders. And considering that mayors do not seem to last more than one term, they are no good at politics as well.
