In addition to the $10 - 15 bill, the projected cost to operate the rail is $120 mill a year.  Of course, you know the "actual" number will be north of $200 mill! There isn't enough people or money in Hawaii to fund and support rail.  Yes "a mere 2%"  and build a couple of townhouse projects and that wipes that out and we're back to where we started.  Quick road to bankruptcy.
