your math is nonsensical.  commuting goes both ways and commuting time is 2 hours in the morning and 2 hours in the afternoon.  And this goes on for 200 days a year for 40 to 50 years.   and not to mention other times when tourists and other passenger uses the train. Plus the current spine will allow for expansion to UH manoa, waikiki and west kapolei, picking up more ridership.  it is this kind of misguided thinking that you antis make, totally ludicrous statements.
