Honolulu’s much-debated elevated light metro rail system has begun its “Trial Running” phase, per Honolulu Authority for Rapid Transit‘s (HART) press release. Considered the final set of tests prior to launching the service, this phase will test all systems including train cars, rail stations, and personnel, over a period of weeks.

Per the press release, multiple cars will be running between Kapolei and Aloha Stadium, 24 hours a day, 7 days a week. Testing is expected to continue until operations are deemed ready for public service. It may be a welcome sight for drivers to see train cars moving on the billion-dollar rail project, but officials urge commuters to keep their eyes on the road, and not at the train cars.

The final station east-bound has been a hot topic among residents, where many feel the ridership will suffer greatly if the system isn’t fully-built to Ala Moana Center or even University of Hawaii’s Manoa campus. Federal rail funding will likely play into the final result of the system, though officials have said it may be extendable in the future with additional funds.
