Electricity alone paid to HECO for the rail will cost well over $100 million.  Add $50 million HECO will charge for maintenance and salaries for the NEW HECO fossil fuel electric generator needed to power hungry Oahu train to nowhere.  Add another $150-200 million to maintain a steel on steel turn of century heavy rail which was NEVER designed to run in humid, tropical,  year round corrosive salt air environment that is merciless to the steel train and all of it metal propulsion and electrical components need to make the train run.  More accurate yearly maintenance for the Oahu train alone is more like over $300 MILLION per year.
