If the City is having this much problems with phase 1, what makes you tihink they won't have even more problems with trying to build phase 2 to Manoa?  As it stands right now, buidling rail from the Ewa plain to Ala Moana Center will cost more than $10 billion dollars, and that is not factoring in the costs to maintain the rail system: phase 2 to Manoa would probably cost upwards of another 5 billion.  So why not instead plan a spur line to Wahiawa, and actually plan to cut down on traffic congestion?  UH Manoa can be better served by the Bus, than it would by rail.  think about it..............
