Center (TOCC). After this phase, combined static and dynamic testing of Segment 2 with Segment 1 began in September 2024. Earlier this year, several major milestones were completed, including the migration of communications, SCADA, fire detection, traction electrification and their related subsystems from the TOCC into Segment 1 and the existing main and backup Operations Control Center (OCC). Integrated system testing for both segments is conducted during non-revenue service hours at night to ensure uninterrupted passenger service on Segment 1 during regular operating hours. Lea+Elliott also continues to support the coordination of documentation and reviews that are needed to verify Operational Readiness per the FTA’s OP54 checklist. We support HART with the provision of verification evidence to Hawaii Department of Transportation (HDOT), the FTA’s State Safety Oversight Agency in Hawaii. These ongoing efforts are positioning the project for a successful transition into the Trial Operation phase and ultimately, full passenger service.

HONOLULU - The Honolulu Authority for Rapid Transportation (HART) is progressing toward Operational Readiness later this year for Segment 2, which connects the Aloha Stadium Station to the Kalihi Transit Center Station. Achieving Operational Readiness for this segment will allow HART to formally turn this segment over to the City and County of Honolulu’s Department of Transportation Services (DTS) for the commencement of passenger service as well as operations and maintenance. This second, elevated segment will add 5.2 miles of guideway and four additional stations extending the system to almost 16 miles long with 13 stations. Just as with Segment 1, Lea+Elliott staff have been actively supporting HART in overseeing the Core Systems work and coordinating efforts with other consultants, contractors and stakeholders throughout the design, construction and testing phases of the Project and this segment. Following the opening of the initial 10.75 miles segment on June 30, 2023, this 5.2-mile rail extension will provide transit riders with improved access to key destinations, including Daniel K. Inouye International Airport and Pearl Harbor, a major employment hub. The system testing teams are completing the system Integration Testing phase, the final step before entering Trial Operations and achieving full Safety Certification of the system. Most of the static and dynamic testing on Segment 2 was independently conducted using the Temporary Operations Control
