The Project

The Honolulu Authority for Rapid Transportation (HART) is building America’s first fully-automated driverless, urban light metro rail system. It will provide reliable mobility in areas of the corridor where people of limited income and an aging population live and will serve rapidly developing areas by linking key employment centers, visitor destinations, and residential communities along the 20-mile east-west corridor on the south shore of the island of O‘ahu.

About the Project

The purpose of the Honolulu Rail Project is to provide high-capacity rapid transit in the highly congested east-west transportation corridor between Kapolei and Ala Moana Center. The Project is intended to provide faster, more reliable public transportation service than can be achieved with buses operating in congested mixed traffic. Rail will also provide additional transit capacity and an alternative to private automobile travel as well as improve transit links within the east-west corridor. Other benefits include:

  • Travel time from Kualaki (East Kapolei) Station to Kālia (Ala Moana Center) Station will be 42 minutes, which will include the time spent at the stations for
    loading and unloading passengers on and off the trains.
  • The Project will connect West O‘ahu with downtown Honolulu and Ala Moana Center via Daniel K. Inouye International Airport.
  • The system features modern electric steel-wheel trains that travel on steel-rail.
  • Future extensions could serve other areas including the University of Hawai‘i-Mānoa, West O‘ahu, Salt Lake, and Waikīkī.

Benefits of Rail

Rail transit will be a fast, affordable, safe, and reliable alternative to driving for many commuters.

The elevated rail system will provide passengers with a congestion-free commute.

More than 100,000 passenger trips every weekday are forecast for the rail system.

Rail construction has created thousands of jobs, and Transit-Oriented Development around rail stations will infuse our economy with billions of dollars after the rail project is completed.

The System

  • The 20-mile rail system will include 21 stations and will be the heart of O‘ahu’s public transportation system.
  • Rail will be fully integrated with the City bus system. A single system-wide transit smart card will be used by passengers to move seamlessly between TheBus and the rail system.
  • Educational institutions along the alignment include UH-West O‘ahu, Leeward Community College, Honolulu Community College, and Hawaii Pacific University. An extension to UH-Mānoa can be built as the project is expanded in the future.
  • The rail system will link the growing region of West O‘ahu with the Daniel K. Inouye International Airport, downtown Honolulu and Ala Moana Center.
  • Rail transit will be powered by electricity and benefits from the most promising advances in alternative energy sources, such as solar, wind and biofuels.
  • The rail system will be operated from the 43-acre Leadership in Energy and Environmental Design (LEED) certified Rail Operations Center (ROC), which is also where the train fleet will undergo servicing and maintenance. The ROC is located between Waipahu High School and Leeward Community College.
