Honolulu Skyline Rail: Stations, Fares, and Park-and-Ride Lots

The Honolulu Skyline opened to the public on June 30, 2023, making it the first urban rail system in the state of Hawaii. It is one of the few fully automated, driverless metro lines in the United States, running along elevated guideway roughly 60 feet above existing roads.

The Honolulu Authority for Rapid Transportation (HART) handles construction, while daily operations fall under the city’s Department of Transportation Services. The original Phase 1 segment serves nine stations across roughly 10.75 miles between East Kapolei and the Halawa platform at Aloha Stadium; Phase 2 added four more stations to the airport and Middle Street when it opened October 16, 2025.

For households relocating from the mainland and weighing where to live, Skyline reshapes the commute math. A West Oahu home that once meant a 45-minute morning crawl along the H-1 freeway can now be paired with a $3 fare and a published travel time of about 21 minutes to Aloha Stadium. Phase 2 extended service to the airport and Middle Street when it opened October 16, 2025, and Phase 3 is underway toward the Civic Center, which will bring the full system to roughly 18.65 miles and 19 stations.

How the system works at a glance

Skyline trains run on a fully automated, third-rail electric guideway with no driver onboard. Following the Phase 2 opening in October 2025, service operates daily from 4 a.m. to 10:30 p.m., with trains arriving every 10 to 15 minutes. Trains arrive roughly every 10 minutes during peak periods on weekdays and every 15 to 20 minutes during off-peak windows.

End-to-end travel from East Kapolei to Aloha Stadium currently takes about 21 minutes when service runs on schedule. Each four-car train can hold roughly 800 passengers under crush load. The cars are built by Hitachi Rail and were partially assembled at a facility in Pittsburg, California, before shipping to Oahu.

Skyline charges a flat $3 per adult single ride, regardless of how many stations a rider crosses. Youth fares run $1.50, and a day pass tops out at $7.50 for adults and $3.75 for youth. The fare also covers transfers to and from TheBus within a 2.5-hour window, an important feature for households arriving without a vehicle.

Phase 1: the nine stations now open

Skyline’s first operating segment runs from the Kapolei plain on the leeward side of Oahu eastward through the Ewa plain and along the Pearl Harbor coast. Each station carries a Hawaiian place name beside its English wayfinding name, recognizing the ahupuaʻa or locality it serves.

The current termini are East Kapolei (Kualakaʻi) on the west and Aloha Stadium (Hālawa) on the east. Two of the stations function as full park-and-ride anchors, while the others connect to bus routes, the University of Hawaii West Oahu campus, and Leeward Community College.

East Kapolei (Kualakaʻi)

The western terminus sits near Kualakaʻi Parkway and Kapolei Parkway, with a multi-level park-and-ride garage offering more than 625 free stalls. The station serves the rapidly growing Kapolei and Ewa Beach areas, including new master-planned developments. Riders heading downtown from Kapolei homes have a fixed 21-minute trip to the current eastern terminus and a flat $3 fare.

UH West Oahu (Keoneʻae)

Located on the western edge of the UH West Oahu campus, this station was built into the original alignment to support student and faculty travel. The campus enrolls roughly 3,100 students, and the station provides a direct alternative to driving along Farrington Highway during peak class hours. A pedestrian bridge connects platforms to campus walkways.

Hoʻopili

The Hoʻopili station sits next to the master-planned Hoʻopili community, which is expected to add roughly 11,750 housing units when fully built out. The station opened without a dedicated park-and-ride lot, on the premise that residents would walk or cycle from nearby blocks. Local feeder buses serve riders from Ewa Beach.

West Loch (Honouliuli)

West Loch serves the older Honouliuli neighborhood and feeder buses moving through Waipahu’s western edge. The station functions primarily as a walk-up and bus-transfer point rather than a park-and-ride. It is also one of the closest stations to West Loch Shoreline Park, a small ocean-side green space along the Pearl Harbor coast.

Waipahu (Pouhala)

Located adjacent to the Waipahu Transit Center, this station carries one of the heaviest bus-transfer loads on the line. Roughly a dozen TheBus routes meet at the Pouhala platform, including the 40 and 432, which both feed neighborhoods south of Farrington Highway. A small surface lot provides about 40 spaces for short-stay parking.

Leeward Community College (Hālaulani)

The Hālaulani platform was constructed inside the Leeward Community College campus, which enrolls more than 6,000 students each semester. Campus parking serves the station with a posted permit, and a dedicated walkway leads from the platform to the main academic quad. The location shortens commutes from the Ewa plain and Mililani toward classes on campus.

Pearl Highlands (Waiawa)

Pearl Highlands sits at the H-1 and H-2 freeway interchange, the busiest road junction in the state. A park-and-ride garage of approximately 1,600 stalls was planned at this location, sized to capture central Oahu commuters from Pearl City, Mililani, and Wahiawa. The garage has been a major driver of the Phase 2 schedule slippage covered by Honolulu Civil Beat throughout 2024 and 2025.

Pearlridge (Kalauao)

The Pearlridge platform connects directly to Pearlridge Center, the largest enclosed shopping mall in Hawaii with about 170 stores. A pedestrian bridge crosses Kamehameha Highway between the station and the mall’s Uptown wing. There is no dedicated park-and-ride at this station, but mall parking is generally open during retail hours.

Aloha Stadium (Hālawa)

The current eastern terminus serves Aloha Stadium, undergoing reconstruction as the New Aloha Stadium Entertainment District. The site provides surface parking that fluctuates with construction phasing, generally around 600 stalls on normal weekdays. Buses connect from this platform to Joint Base Pearl Harbor-Hickam, drawing steady military commuter ridership.

Fares and the Holo card

Skyline shares its fare system with TheBus through the Holo card, a reloadable contactless smart card managed by the city. A Holo card costs $2 to obtain and can be loaded with stored value or passes online, at retailer kiosks, or at ticket vending machines installed on every Skyline platform. A single ride deducts $3 from the stored balance, and any second tap within 2.5 hours becomes free as a transfer.

Fare capping is one of Skyline’s most useful features for new arrivals. Adult riders cap at $7.50 in a single day, so any taps after the second $3 ride add no charge until midnight. Monthly fares cap at $80 for adults regardless of how many rides are taken. Youth, senior, and disabled riders use sharply reduced fare ladders.

Tapping is the only accepted fare action. Skyline does not sell paper tickets aboard trains, and cash is not accepted at fare gates. New arrivals can buy a Holo card at the airport, ABC Stores, Foodland, Times Supermarkets, or the city’s downtown service center on King Street. The card can also be reloaded by phone using the Holo Card app for iOS and Android.

How Holo handles family travel

Each rider needs their own Holo card. Adults cannot tap twice on a single card to pay for two passengers, and a family of four traveling together must each carry their own card. This is a meaningful detail for visiting relatives — a household hosting in-laws over Thanksgiving will want to pre-load four cards before the airport pickup.

Mobile wallets and credit card taps

As of the most recent rollout, Apple Pay, Google Pay, and contactless credit cards are not yet accepted at Skyline fare gates. The system runs on the Holo network only. A test of open-loop payments has been planned by the city’s Department of Transportation Services, but no public launch date has been announced for Skyline platforms.

TheBus transfers and integrated transit

Skyline’s most important everyday feature for non-car households is the free transfer between train and bus within 2.5 hours of the first tap. A rider who taps into Skyline at Pearlridge and then onto a route 40 bus at Waipahu pays $3 total, not $6. The Holo card tracks the transfer automatically, which keeps fares predictable for someone learning how to live on Oahu without a personal vehicle.

Most Skyline stations connect to multiple TheBus routes, with the busiest transfer hubs at Waipahu Transit Center and Aloha Stadium. Waipahu’s transit center includes bus bays for routes feeding Ewa Beach, Makakilo, and the central business district along Farrington Highway. Aloha Stadium’s platform serves shuttle and express buses heading downtown along H-1.

Bus connections at East Kapolei are still being expanded as ridership data informs route changes. The CountryExpress route C, for example, was reshaped in 2024 to feed Skyline rather than run continuously to downtown, shortening some buses and tightening headways on the Skyline approach. Local reporting at Hawaii News Now covered the route revisions when they took effect.

Park-and-ride lots at terminal stations

Park-and-ride capacity is concentrated at the system’s eastern and western anchors, plus the planned mega-garage at Pearl Highlands. Smaller surface lots exist at Waipahu (about 40 stalls), and on campus at Leeward Community College and UH West Oahu, though campus lots carry their own permit rules. Park-and-ride parking at Skyline-owned lots is currently free for transit users.

East Kapolei’s garage holds roughly 625 stalls across a multi-level structure built on the south side of the platform. The lot is signed for transit users, and overnight parking is not permitted. Aloha Stadium provides about 600 surface stalls in the asphalt fields around the platform, with counts fluctuating as the New Aloha Stadium Entertainment District redevelopment proceeds.

Pearl Highlands: the keystone of Phase 2

The Pearl Highlands park-and-ride garage is designed to handle commuters from Mililani, Wahiawa, and Pearl City who reach the H-1/H-2 interchange and would otherwise sit in traffic for another 30 to 45 minutes to downtown. The garage was originally targeted to open alongside Phase 1 in 2023, but design and construction revisions pushed completion into a later schedule.

HART and the city deferred the Pearl Highlands garage from the project, citing excessive construction costs at the originally planned location. The agency is exploring alternative park-and-ride sites to serve Mililani, Wahiawa, and Pearl City commuters, though no replacement design had been confirmed as of mid-2026. Households researching Pearl City budget tradeoffs should not plan car-free living around a Pearl Highlands garage in the near term.

Phase 2: extension toward Pearl Highlands and the airport

Phase 2 of the project is bundled with completion of the Pearl Highlands garage and continuation of revenue service east toward the Honolulu International Airport. The extension adds approximately 5.2 miles and pushes Skyline closer to the urban core. New stations include the Honolulu Airport platform, Lagoon Drive, the Pearl Harbor Naval Base, and an interim terminus at Middle Street.

The airport station is the segment’s headline draw. Travelers will be able to board Skyline at the inter-island terminal and reach Aloha Stadium in roughly 10 minutes, or East Kapolei in about 30 minutes. The airport platform is sited between the inter-island and mainland terminals, with a sky bridge of about 850 feet connecting platforms to the terminal complex.

Pearl Harbor Naval Base station

The Pearl Harbor Naval Base platform sits within the secure perimeter requirements of Joint Base Pearl Harbor-Hickam, and access protocols are still being worked out between HART and Navy security. Public riders boarding at the station will use an entrance separated from base-side egress. Roughly 17,000 active-duty personnel are assigned to the joint base.

Honolulu Airport station

The airport platform is designed for visitor luggage as well as commuter loads. Trains include standing space and limited seating, so families with multiple checked bags should expect a tight ride during morning peaks. The baggage policy mirrors TheBus rules — riders are limited to two carry-on-size bags per person aboard the train.

Middle Street terminus

Middle Street will function as Phase 2’s eastern terminus and a major bus-transfer point for downtown-bound commuters. The existing Middle Street Transit Center already handles dozens of TheBus routes, and Skyline trains will share that footprint. This interim terminus is intended to be the largest bus connection on the line until Phase 3 reaches downtown.

Phase 3: alignment to the Civic Center

Phase 3 carries Skyline from Middle Street through Kalihi, Iwilei, Chinatown, and downtown Honolulu to a final terminus at the Civic Center, near Honolulu Hale and the State Capitol. The alignment shifts from elevated guideway along H-1 to a more urban path through dense city blocks. Construction is the most demanding section of the project, with utilities, historic structures, and tight rights-of-way along the route.

Stations planned for Phase 3 include Kalihi, Kapalama, Iwilei, Chinatown, Downtown, and Civic Center. The Civic Center platform is intended to serve roughly 40,000 daily workers in the downtown core. As of 2025, HART was estimating Phase 3 substantial completion in the early 2030s, with revenue operations targeted at varying dates depending on funding decisions. The Star-Advertiser has tracked the funding negotiations across multiple legislative sessions.

Operating hours, frequency, and rolling stock

Skyline trains now operate daily from 4 a.m. to 10:30 p.m. following the Phase 2 expansion in October 2025. The City and County of Honolulu expanded hours when Phase 2 opened, delivering a service window substantially longer than the original Phase 1 schedule of 5 a.m. to 7 p.m.

Peak frequency is roughly every 10 minutes during weekday rush hours, with off-peak headways running every 15 to 20 minutes. The Hitachi Rail four-car trains can theoretically run as frequently as every 3 minutes, but staffing, ridership, and customer service center hours have kept actual frequencies more conservative through 2025.

Vehicle specs

Each train is a four-car driverless vehicle built by Hitachi Rail. Trains run on a 750-volt DC third rail. The maximum operating speed is 55 miles per hour, but average commercial speed including station dwell averages about 30 to 32 miles per hour. Each car carries approximately 200 passengers under crush load conditions.

Accessibility

Every Skyline station is fully ADA-compliant with elevators, tactile guidance strips, and audible alerts. Platforms are level with train floors, eliminating the boarding gap common at older transit systems. Service animals are permitted, and the line accommodates wheelchair, scooter, and walker users without crew assistance — a relevant feature for relocating seniors or households with disabilities.

Practical use cases for relocating households

For families moving from the mainland and weighing West Oahu housing against urban rents, Skyline reshapes the typical Oahu commute calculation. A two-bedroom condo in Kapolei may rent for about $2,400 a month, while a comparable unit in Makiki often runs $2,900 or more. The Skyline trade-off is roughly 21 minutes by train versus 35 to 60 minutes by car along the H-1 corridor during peak periods.

A second use case is car-free or car-light living. The H-1’s average peak speed drops to under 20 miles per hour during morning and evening rush, making the rail-and-bus combination time-competitive between the Ewa plain and central Oahu. Households researching Honolulu cost of living often find that one fewer car saves $750 to $900 per month including insurance, gas, and parking.

Reverse commutes and weekend use

Reverse commutes — riders living near Pearl City or Aiea and working in Kapolei industrial zones — are some of Skyline’s most underused trips. Trains run both directions on the same headways, so a 6:00 a.m. westbound train carries far fewer passengers than its eastbound counterpart. Anyone with a flexible work site at UH West Oahu, Kapolei, or the leeward industrial parks benefits from emptier westbound trains.

Visitor logistics

For visiting family arriving at the airport, Skyline now connects directly to Daniel K. Inouye International Airport via the Phase 2 extension, which opened October 16, 2025. Travelers board at the airport platform and reach Aloha Stadium in roughly 10 minutes, or continue west to East Kapolei in about 30 minutes. The airport station uses the same flat $3 fare with free TheBus transfers, making it the most affordable ground transport option from the terminal for households relying on transit.

Sticker-shock comparisons with mainland transit

Skyline fares are modest by mainland metropolitan standards. New York’s MTA charges $2.90 per ride, Washington’s Metro charges up to $6.50 at peak distance, and the San Francisco BART can exceed $11 for long suburban runs. Skyline’s flat $3 fare with free TheBus transfers compares favorably for a 19-station eventual system, particularly when combined with the $80 monthly cap.

Pairing rail with food and fitness routines

Households planning car-light routines often build errands around the line. A Pearlridge tap lets riders walk into the mall and connect to Honolulu poke counters via TheBus 32, while Aloha Stadium connects to gym networks listed in coverage of Honolulu gyms. Pre-loaded Holo cards and well-planned transfers turn a $3 tap into a half-day errand loop without parking fees.

Funding, oversight, and where to follow updates

The Skyline project is funded through a combination of federal Full Funding Grant Agreement money from the Federal Transit Administration, a half-percent general excise tax surcharge collected by the state Department of Taxation, and a portion of the transient accommodations tax. Total project budget estimates have climbed from $5.2 billion at the original 2009 estimate to over $9.9 billion through 2025.

Project oversight is shared between HART, the City and County of Honolulu, the State of Hawaii, and the FTA. Public HART board meetings are streamed monthly, and project updates are posted on the agency’s website. The Hawaii Department of Taxation tracks the GET surcharge that flows into the project budget, and longer-form investigations into project finance appear at Civil Beat.

Frequently asked questions

How much does a single Skyline ride cost?

A single adult ride on Skyline is $3.00, paid by tapping a Holo card at the fare gate. Youth fares are $1.50, and seniors or disabled riders pay $1.25 per ride. The fare includes free transfers to and from TheBus within 2.5 hours, and daily fares cap at $7.50 for adults regardless of how many additional taps occur during that day.

How many stations does Skyline have right now?

Skyline currently has thirteen operating stations across two segments. The original nine (East Kapolei to Aloha Stadium, 10.75 miles) opened June 30, 2023. Four additional stations — Joint Base Pearl Harbor-Hickam, Daniel K. Inouye International Airport, Lagoon Drive, and the Middle Street Transit Center — opened October 16, 2025, extending service into the urban core. Phase 3 will add six more stations toward downtown Honolulu and the Civic Center.

Where can riders park near a Skyline station?

The largest free park-and-ride lots are at East Kapolei with about 625 stalls and Aloha Stadium with roughly 600 surface stalls. Waipahu has a smaller 40-stall lot. The future Pearl Highlands garage will add approximately 1,600 spaces once it opens. Campus stations at UH West Oahu and Leeward Community College have limited spaces available with appropriate parking permits.

Does the Holo card work on both Skyline and TheBus?

Yes. The Holo card is the shared fare medium for Skyline, TheBus, and connector services such as the Waikiki Trolley’s blue line. A single tap covers travel on either system for 2.5 hours, including free transfers between train and bus. Cards can be purchased for $2 at retailers, online, the city service center, and ticket vending machines on every Skyline platform.

When will Skyline reach the Honolulu airport?

Skyline reached Daniel K. Inouye International Airport when Phase 2 opened on October 16, 2025. The airport platform is sited between the inter-island and mainland terminals, connected by a sky bridge. A single $3 Holo card tap at the airport includes a free transfer to TheBus, and service runs daily from 4 a.m. to 10:30 p.m. Riders heading to Waikīkī or downtown should transfer at Lagoon Drive or Middle Street to one of the rapid bus routes that connect Phase 2 stations to Ala Moana, UH Mānoa, and the Waikīkī resort corridor.

Are Skyline trains air-conditioned?

Yes, every Hitachi Rail train running on Skyline is fully air-conditioned, which matters during summer months when Honolulu daytime highs regularly hit 88 to 90 degrees Fahrenheit. Platforms are open-air with shaded canopies, so brief exposure to heat is expected before boarding. Some stations include cooled waiting areas, and service animals are accommodated without an additional fare.

Can riders take bikes on Skyline?

Skyline allows full-size bicycles in the designated areas of each train car, and bike racks are installed at every station. There is no additional fare for bringing a bike aboard, though riders are asked to avoid the most crowded peak hours. E-bikes and scooters with batteries under standard size limits are permitted, with foldable bikes treated as carry-on baggage during peak service windows.
