Integrating KAI’s Intermodal Services to Connect Journeys Across Java and Sumatra
Traveling from Bandung to the office districts in Jakarta can now involve several train services. Customers can depart by Whoosh high-speed train, get off at Halim Station, and transfer to the LRT Jabodebek to continue their journey to the Kuningan or Dukuh Atas areas. In other cities, similar journeys are made possible through combinations of trains with Commuter Line services, airport trains, or urban transportation.
These options demonstrate how Indonesia’s transportation networks are becoming increasingly interconnected. PT Kereta Api Indonesia (Persero), or KAI, recorded 394,443,300 customers served by KAI Group from January to September 2026, an increase of 7.06% compared with 368,429,917 customers during the same period in 2025. This mobility is supported by various services with distinct characteristics, ranging from intercity travel to urban transportation and airport access.
KAI Vice President of Corporate Communication Anne Purba said that people need transportation services that enable them to complete their journeys from their departure points to their final destinations. Therefore, connectivity between services plays an important role in helping customers choose journeys that suit their needs.
“For customers, the most important thing is being able to reach their destinations through journeys that are easy to plan. Some travel by intercity train before continuing by LRT, others transfer to airport trains, while some use buses to reach residential areas or workplaces. These options are already available in several cities and help people with their daily activities,” Anne said.
In Jakarta, integration between Whoosh and LRT Jabodebek is available through the connecting bridge at Halim Station. Customers arriving from Bandung on Whoosh can reach Halim LRT Jabodebek Station without having to transfer to road transportation first. From there, they can continue their journeys to Cawang, Kuningan, Rasuna Said, Setiabudi, and Dukuh Atas stations. The Whoosh Halim Station area also provides access to Transjakarta services, buses to Soekarno-Hatta Airport, transportation to Halim Perdanakusuma Airport, taxis, and ride-hailing services.
Another connection is available between Cawang Commuter Line Station and Cikoko LRT Jabodebek Station. Commuter Line customers traveling from Bogor, Depok, or Jakarta can continue their journeys using the LRT Jabodebek through the connecting access between the two stations. On these services, the KAI Commuter Multi Trip Card (KMT) can also be used to pay for Commuter Line and LRT Jabodebek journeys. In the Dukuh Atas area, customers can transfer between Sudirman Commuter Line, LRT Jabodebek, MRT Jakarta, and other transportation services in the surrounding area.
On the Bandung side, Whoosh Padalarang Station is connected to feeder trains serving Cimahi and Bandung stations, with schedules arranged to facilitate customer transfers. The Padalarang area is also served by Bandung Raya Commuter Line, Trans Metro Pasundan buses, and feeder services to Kota Baru Parahyangan. With these options, Whoosh journeys can continue to central Bandung and other surrounding areas.
The scale of travel demand for urban and high-speed rail services is reflected in KAI Group data. From January to September 2026, LRT Jabodebek served 24,702,905 customers, an increase of 18.94% compared with the same period in the previous year. During the same period, Whoosh served 4,576,841 customers, representing growth of 1.16%, while KAI Commuter served 312,302,440 customers, an increase of 6.38%.
In Yogyakarta, integration takes place through four complementary rail service groups. Yogyakarta Station serves as a hub for long-distance and local trains, the Yogyakarta–Palur Commuter Line, the Yogyakarta–Kutoarjo Prameks service, and airport trains to Yogyakarta International Airport (YIA) via Wates. Customers arriving from Jakarta or Surabaya, for example, can continue their journeys to Solo using the Commuter Line, to Kutoarjo using Prameks, or to YIA by airport train. Yogyakarta Station also provides access to Trans Jogja services.
The extensive use of these services is reflected in KAI data through September 2026. Customer activity on long-distance and local trains operated by Daop 6 Yogyakarta reached 11,996,034, an increase of 11.00%. Meanwhile, the Yogyakarta–Palur Commuter Line served approximately 7.16 million customers, Prameks served approximately 870,000 customers, and YIA airport trains served approximately 2.01 million customers. Based on the consolidated number of customers boarding or recorded through gate-in across services, Yogyakarta Station recorded 5,488,259 customer movements, followed by Lempuyangan with 2,114,387, Solo Balapan with 1,958,718, Purwosari with 883,399, and YIA Station with 838,793.
“Yogyakarta is an interesting example because intercity, commuter, regional, and airport rail services converge in the same area. Customers can arrive from other cities and continue their journeys to Solo, Kutoarjo, or the airport. This connectivity gives people more travel options, including for education, trade, and tourism,” Anne explained.
In Semarang, connections between rail services and urban transportation are provided through the Trans Semarang Bus Rapid Transit (BRT) system. Corridor IV connects the Semarang Tawang and Semarang Poncol station areas with several locations across the city, including Jalan Pemuda, City Hall, Tugu Muda, Karangayu, and areas toward Ngaliyan and Cangkiran Terminal. Customers arriving at Tawang or Poncol can use the BRT network to continue their journeys to public service facilities, residential areas, and other activity centers. From January to September 2026, customer activity on long-distance and local trains operated by Daop 4 Semarang reached 10,949,458, an increase of 9.12%.
Meanwhile, in Surabaya, a concrete example of integration with urban transportation is provided by the WiraWiri Suroboyo feeder service on route FD07. Connecting Bratang Terminal with Surabaya Pasar Turi Station, the route passes through the Surabaya Gubeng Baru Station area, supporting customer journeys between two major station areas and several urban activity centers. In the Wonokromo area, access to bus networks and urban transportation services also provides additional travel options, subject to the available service stops. Customer activity on long-distance and local trains operated by Daop 8 Surabaya reached 9,738,167 from January to September 2026, an increase of 7.69% compared with the same period in 2025.
Similar connectivity is also available in Sumatra, with a strong focus on links between city centers and airports. In North Sumatra, the Srilelawangsa Train connects Medan Station with Kualanamu Airport Station, which is directly integrated with the airport terminal area. Customers can transfer from the train to the flight terminal through access within the airport complex. Meanwhile, in West Sumatra, the Minangkabau Ekspres Train connects Padang city with Minangkabau International Airport. Transfers from the station to the terminal are facilitated by a 136-meter-long skybridge, which resumed operations in June 2025.
In Palembang, the South Sumatra LRT connects Sultan Mahmud Badaruddin II Airport with various areas of the city, including Asrama Haji, Bumi Sriwijaya, Ampera, and DJKA. Its connectivity is complemented by the Musi Emas LRT feeder network. Documentation of the feeder network lists eight corridors, including Asrama Haji–Sematang Borang, Asrama Haji–Talang Betutu, Polrestabes–Kompleks OPI, DJKA–Pasar Plaju, and RSUD–Sukawinatan. These services help extend the reach of journeys from LRT stations to areas not served by rail lines.
From January to September 2026, the South Sumatra LRT served 3,303,595 customers. During the same period, customer activity on long-distance and local trains reached 4,123,614 in Divre I North Sumatra, 3,467,280 in Divre II West Sumatra, and 1,793,105 in Divre III Palembang. These figures illustrate the diverse travel needs across Sumatra, with integration arrangements adapted to the conditions of each region.
Anne said that connectivity between these services highlights the importance of cooperation among railway operators, local governments, airport managers, and urban transportation operators. Each region has different travel patterns, making convenient transfers, pedestrian access, service information, and onward transportation essential to meeting public needs.
“From Halim, which connects Whoosh and the LRT, to Yogyakarta with its four groups of rail services, Surabaya with its feeder transportation, and Medan, Padang, and Palembang with their airport connections, people already have a variety of travel options. We hope that the available intermodal connections will continue to be utilized to support economic activities, education, tourism, and daily mobility across different regions,” Anne concluded.
