Trial Operations Begin on Segment 2:

HART's Construction Progress and Updates:

Trial Operations for Segment 2 began on July 26, 2025. This phase includes rigorous testing of 26 different operating scenarios and a System Service Availability Demonstration, which measures the system’s performance and reliability. Hitachi Rail Honolulu, the City’s contracted operator of Skyline, must achieve an availability of 98.5% average over a 30-day rolling period, which is projected to be completed by mid-September. 

The current projected date for opening Segment 2 is October 15, 2025. As with Segment 1, this date is contingent on meeting the necessary safety and service availability requirements.

Once the required testing and safety documentation is completed, Segment 2 assets will be transferred to the Department of Transportation Services (DTS) for passenger service.

During Trial Operations, HART reminds the public that eastbound passengers must disembark the train at Aloha Stadium Station before it enters Segment 2. The train will then travel through Segment 2 without passengers on board. Once it returns westbound to Aloha Stadium Station, passengers may board the train to continue their trip.

Segment 2 - Airport Guideway & Stations:

  • Rail guideway construction and trackwork are complete; the four stations in this segment are expected to be completed in Q1 2025.

  • Core systems is nearly complete.

  • The third rail is now energized, and vehicle train testing is underway.

  • The anticipated transfer of assets to DTS is planned for late 2025 for the opening of service.


Business and Community Meeting:

Segment 3 - City Center Section:

Utilities relocation is underway:

  1. Downtown: Completion expected in Q1 2025

  2. Dillingham: Completion expected in Q1 2026

HART and its contractors held an online business and community meeting on Thursday, January 30, 2025 via Zoom. The meeting covered ongoing projects, lane closures, and public impacts in the City Center segment of the Honolulu Rail Transit Project, including areas such as Kalihi, Iwilei, Downtown, Chinatown, and Kaka’ako.

Please see the below traffic plans and mark ups for a general look at the road conditions.

Traffic Plan Summary:

  • Kamehameha Highway and Dillingham Boulevard, from Middle Street to Kaaahi Street, will operate with one traffic lane in each direction 24 hours a day, 7 days a week. There will be coning and tapering on the road to ensure a safe and smooth transition around the work zone.

  • Left turns from Kamehameha Highway and Dillingham Boulevard are restricted, as well as left turns from businesses and residential driveways onto Kamehameha Highway and Dillingham Boulevard.

  • Left and right turns from the cross streets onto Kamehameha Highway and Dillingham Boulevard are allowed. However, left or right turns from the cross streets may be temporarily restricted during nighttime hours.

  • Alakawa Street is the only exception where left turns are permitted from Dillingham Boulevard onto Alakawa Street. This is to alleviate traffic in this congested area.

Utilities Construction Work Along the Project:

  • Middle Street to Puuhale Road: Day time and night time work on gas, water, and electrical utilities.

  • Mokauea Street to McNeill Street: Intermittent day time and night time intersection work on telecommunication and electrical upgrades, streetlight and traffic signal improvements, and property restoration.

What is the HART Rail Guideway Mauka Shift?

The Mauka Shift refers to a plan to move a section of the rail guideway from the center of Dillingham Boulevard to the mauka side of the street. This mauka shift saves time and money for the Project by eliminating the need to relocate certain utilities.

Currently there is a complex web of electricity, water, sewer and fiber optics lines that run under Dillingham Boulevard. There are also two 138-kilovolt power transmission lines above ground on either side of Dillingham Boulevard. On the makai side, there are also 12- and 48-kilovolt power lines. For HART to move all of these power lines underground would be extremely difficult as there is not enough room to provide the clearances needed to service existing utilities. Moving the guideway to the mauka side of the street eliminates the need to bury all of the power lines on the makai side and avoids the need to move other existing underground utilities, thereby improving the Project schedule and reducing costs by approximately $150 million.
