Exactly!
Tren Urbano doesn't serve the areas that it needed to enhance its capacity design.
It served the contractors and developers bank accounts probably also public officials. 
It was said that the bidding process was wrought with favoritism and sweetheart deals especially with real estate acquisitions.
It still serves over 10000 people per day and has the infrastructure to handle 4x more.
It was completed and operational way before hart's rail.
How's that for a place that isn't even a state as yet.
Although I don't consider a complete success of rail with this project in comparison with Hart it can attribute many similar issues with anti rail movements that intended to stall and resulted in steep cost escalations.
That is the poker hand that stabs the residents of an island metropolis like Oahu.
The developers and contractors can see your cards and count  on anti rail devolopment to up the ante toward the cards they can redraw.
