Cayetano is a fricken idiot. He sucked as a governor and now he's going to run for mayor just because he doesn't like the rail idea? Sound like another personal agenda to me. Id rather see bu'laia run for mayor then cayetano. 
I've ridden forms of the rail all over the world. Once the main line is connected to the transfer stations it would be beneficial to the island. Hawaii people are so afraid of change. That's probably the reason why we can't get concealed carry permits. Paranoia. 
Let's review some facts of RAIL. Originally Mufi promised RAIL would be $3B, others said it would be $5B. We are currently projecting potentially into the $6B range. In order for RAIL to have been approved to even move forward Mufi had to secure the vote from the Salt Lake folks with the guarantee that the RAIL would run through Salt Lake and not bypass them. This turned out to be a lie. As we now know the Salt Lake contingent got the shaft and are now bypassed. The C&C for at least a year held onto a routing that they knew was too close to the runway approach for HNL International Airport. The rerouting cost the C&C (that means you and me) $125M and lost momentum for the project. Am I not supposed to assume that this was a political handout to the designers by the Hanneman Administration? Unless you've forgotten the C&C lied and said they did not know anything about it, but later records clearly indicated otherwise.
Now with regards to the "main line" get connected to transfer stations? There are no transfer stations, there is a single line running into town that's it. No spurs out to other communities at this time. The RAIL is being built from Kapolei into town. The RAIL riders cannot hit downtown until the entire line is completed. Instead of building from downtown outwards the construction is slated to go in the other direction.........stupid. Any proposed RAIL spur to UH is not even on the horizon and there is absolutely no money to build it. Heck there is not enough money to build the current RAIL.
Now let's take a look at the RAIL stations themselves. You need to condemn land and kick people out to build the stations, the parking lots (yes there will need to be parking lots at the stations), and rerouted The Bus to service the stations and implement new routes. So.........the morning commuter catches The Bus to the station, waits at the station, gets let off somewhere outside of downtown Honolulu (until say 10 - 13 years from now), then catches another Bus to work? Does that make sense? It doesn't to me. Even when the RAIL is completed you catch a Bus, get on a train, get on a Bus and repeat on the way back.
All this talk of RAIL and no one in the current administration or the former Hanneman Administration is talking about mandated changes to the current sewer system on Oahu. These changes are at least in the $3B mark.........yes that's right just as much as the RAIL was to originally cost. There is no money for those repairs.
Now why GZ should we listen to you? Well I have a BSc in Civil Engineering, I work in the construction industry (yes I'm in construction and don't want RAIL and am not alone) and have nearly 20 years in, and finally I've read the RAIL plan and proposed alternate plan. Nothing from my schooling to experience say that RAIL has ever been a good idea.
We're currently into the construction guys and systems people for some serious money, but that doesn't mean we should continue to throw away money and money that we don't even have.
