It's not prudent to continue a project when there's no money available to finish it.  Nobody is even proposing any funding ideas.  There will be more traffic when rail finally takes on passengers compared to traffic before rail construction started.  That's because traffic is always increasing, and the City is not stopping residential construction in rural areas.  Hoopili means that 12,000 new homes will be built on the Ewa Plain.  Some who will live there will take the rail, but many who will commute into town will take their cars.  Koa Ridge means that 3,500 homes will be built in Central Oahu, and the same commute pattern holds for those future residents.  Rail will take so few people off the roads that it can't even accommodate the increase in traffic during its construction period.  And now we find out that it may cost twice as much to finish it.
