FYI: there are two stations on Kualakai Parkway (aka North-South Road). This station is closest to H1 and by University of Hawaii, West Oahu Campus. This is station 2 (station 1 is right by the Kroc Center).
Lots of parking here but I'm finding out that the lot fills up fast and although the grassy area across the street is not designated spots, I've seen cars parked there. If you insist on parking, try Station 3 (Honouliuli) as they have the most parking.
If you've never taken the rail before, it's not hard at all. You must have a Holo card with some funds on it. This card can be purchased at 7-11 or anywhere you get a bus pass. I was gifted my card and i charged/filled it with $20.00. It's basically $3.00 each direction. With that card, you tap the sensor and the gate opens. Walk, take the elevator or escalator to CP level and wait for your ride.
Since this is the second to the furthest west, the only stop west is station 1 (Kroc center and closer to Ka Makana Mall) or go east and get off on your desired stop.
The actual rail has forward facing and side facing (fold down) seats, as well as an area for luggage or big items. I've seen people come on with their e-bikes and regular bikes on here.
Hold on to your Holo card as you'll use it again when you disembark and leave the station. Simply tap the exit screen and the gate opens.
I've used the rail to and from the airport now and it's wonderful!! Only thing, there is no overnight parking for vehicle and the rail starts at 4am and runs to 10pm (for now). read more
