The city Department of Transportation Services will hold night training exercises at the Halawa/Aloha Stadium rail station on Tuesday from 7 p.m. until 11:30 p.m., according to a social media post from the Honolulu Police Department and a HART news release.

“Emergency vehicles will be responding and residents may hear loud noises, including simulated gunfire,” according to HPD.

Drivers are asked to beware of increased traffic in the area. All roads will remain open, police said. The training exercise will happen after the line stops running on Tuesday.

“The emergency training exercise is a routine part of rail operations and will be similar to the training event that occurred in late 2022 at the Kualakaʻi East Kapolei Station,” according to a city news release that noted the exercise is closed to the media. “Motorists, residents and public transit riders should not alarmed at the sight of multiple first-responder vehicles at the station, which will include TheBus, The Handi-Van, the Honolulu Fire Department, the Honolulu Police Department, and Emergency Services Department vehicles.

The city is advising drivers and pedestrians to pay attention to the road during this event. Officials emphasized that the exercise “is a first responder training exercise, and to NOT call 911 related to the event.”

“The training is closed to the general public. Drones will not be permitted in the exercise area,” read the release. “Unlike the previous full-scale exercise, there will be no media availability.”
