If the aerial is popular in town, it may be possible to create additional connections for rail users, such as a Waianae to East Kapolei route, Mililani to LCC route, or perhaps all the way to Hawaii Kai.
These routes are approximate, and station locations may need to be adjusted. For privacy considerations, the view from the lower half of the car windows could be obstructed. Riders wouldn't look down on residents' houses and backyards, but could still enjoy sweeping vistas.
