"So what will the future O'ahu rail system look like? A review of the 1992 plans suggests that it likely will be run above ground along the heavily traveled corridor from Kapolei to just outside downtown Honolulu, with about a dozen stops in between.Riders will be able to take buses or drive their cars to stations, then board 95-foot rail cars that will be electrically powered and equipped with rubber-dampened steel wheels."
