KAI to Complete Delivery of 16 KRL Train Sets from INKA by 2026, Additional 30 Train Sets Under Review Amidst Surging Commuter Demand

Jakarta, Indonesia – PT Kereta Api Indonesia (Persero) (KAI), through its subsidiary PT Kereta Commuter Indonesia (KCI), is on track to finalize the procurement of 16 electric multiple unit (EMU) train sets, commonly known as KRL, from state-owned train manufacturer PT Industri Kereta Api (Persero) (INKA) by 2026. This significant fleet expansion aims to bolster the capacity of the highly utilized KRL Commuter Line serving the Greater Jakarta area. Currently, six of these train sets are already operational, providing much-needed relief to millions of daily commuters.

Karina Amanda, Vice President Corporate Secretary of KCI, confirmed the timeline for the remaining deliveries. "Of the 16 train sets, six are currently operational. The remaining 10 train sets are targeted to be fully operational throughout 2026, in a phased manner," Amanda stated during a press briefing at Commuter Hall in Jakarta on Monday, April 20, 2026. This staggered deployment reflects the complex processes involved in manufacturing, delivery, and rigorous certification.

The seventh train set in this order has already reached the Depok Depot and is undergoing the critical certification process, a prerequisite for commercial operation to ensure safety and compliance with technical specifications. Meanwhile, the eighth train set is presently en route from INKA’s production facility in Banyuwangi, East Java, highlighting the extensive logistical chain involved in transporting these large components across the Indonesian archipelago. "One train set is already at the Depok Depot undergoing certification, and the eighth train set is in the process of being shipped from Banyuwangi," Amanda elaborated, providing a detailed snapshot of the ongoing progress.

This procurement of 16 train sets is distinct from a separate, larger request for an additional 30 new train sets, an initiative personally championed by President Prabowo Subianto. The discussions for this additional batch are reportedly nearing finalization between KAI and the government. "Currently, we are indeed focused on the completion of the 16 train sets that are being produced by our colleagues at INKA. In parallel, our capacity development division is also working on plans for fleet expansion beyond these 30 train sets," Amanda concluded, indicating a multi-pronged approach to addressing the escalating demand for public transportation.

Background and Context: The Growing Demand for Urban Mobility

The KRL Commuter Line is the backbone of public transportation in Jabodetabek (Jakarta, Bogor, Depok, Tangerang, Bekasi), serving an estimated 1.2 to 1.5 million passengers daily before the COVID-19 pandemic. While ridership saw a temporary dip during the pandemic, it has since rebounded strongly, often surpassing pre-pandemic levels on peak days. This surge is driven by several factors: rapid urbanization, population growth in Jakarta’s satellite cities, increased awareness of environmental benefits, and a persistent desire among commuters to avoid the notorious traffic congestion that plagues the capital region.

Jakarta, as Southeast Asia’s largest metropolitan area, faces immense challenges in urban mobility. Traffic jams cost the economy billions of dollars annually in lost productivity and fuel consumption. The KRL Commuter Line offers a reliable, affordable, and increasingly efficient alternative to private vehicles, connecting key residential areas with the city’s central business districts and other economic hubs. However, the existing fleet, while regularly maintained, has been under immense pressure to cope with the ever-growing passenger volume, leading to overcrowded trains, especially during rush hours.

The government, under various administrations, has consistently prioritized improving public transportation infrastructure as a cornerstone of national development. Initiatives like the Mass Rapid Transit (MRT), Light Rail Transit (LRT), and the continuous expansion and modernization of the KRL system are all part of a broader strategy to create an integrated, sustainable urban transport network. The procurement of new KRL train sets from a domestic manufacturer like INKA aligns perfectly with this national agenda, not only addressing immediate transportation needs but also fostering local industrial growth and reducing reliance on imports.

Timeline and Chronology of Fleet Modernization

The journey to modernize and expand the KRL fleet is a continuous one, punctuated by significant milestones. The current 16-train set order from INKA dates back to earlier strategic planning by KAI and the Ministry of Transportation, recognizing the impending need for fleet rejuvenation and capacity enhancement.

• Early 2020s: Initial planning and budgeting phases for new KRL procurements. Discussions with domestic manufacturers like INKA to assess production capabilities and timelines.
• Mid-2020s: Formalization of the order for 16 train sets with PT INKA (Persero). This marked a significant commitment to local production, following a strategy to reduce dependence on imported rolling stock.
• Late 2024 – Early 2025: Commencement of delivery and initial operational deployment of the first few train sets. The first six train sets were gradually introduced into service, allowing KCI to integrate them into their existing schedules and operational protocols.
• April 20, 2026 (as per news): Announcement of the status of the 16-train set order, confirming six operational, one in certification at Depok Depot, and one in transit from Banyuwangi. This indicates a steady, albeit complex, progression.
• Throughout 2026: Phased introduction of the remaining 10 train sets. Each train set undergoes factory acceptance tests, delivery logistics, static and dynamic testing at depots, and finally, operational certification by the Directorate General of Railways (DJKA) under the Ministry of Transportation before it can carry passengers. This meticulous process ensures safety and reliability.
• Beyond 2026: Potential finalization and commencement of production/delivery for the additional 30 train sets requested by President Prabowo. This would represent another substantial leap in KRL capacity.

The process for each train set, from manufacturing to operational deployment, can take several months, involving thousands of man-hours and stringent quality control. INKA’s facility in Banyuwangi plays a crucial role, serving as the manufacturing hub before the completed train sets embark on their journey to the operational depots in Greater Jakarta.

Supporting Data and Fleet Expansion Imperatives

The KRL Commuter Line currently operates with a diverse fleet, a significant portion of which consists of refurbished trains imported from Japan over the past two decades. While these imported trains have served the system well, their increasing age necessitates costly maintenance and eventual replacement. The long-term strategy involves a shift towards locally manufactured trains to ensure sustainability and support national industry.

• Existing Fleet: KCI operates several hundred KRL cars, forming dozens of train sets (typically 8-12 cars per set). Many of these trains are over 20-30 years old, having been acquired second-hand from Japanese railway companies.
• Ridership Growth: Post-pandemic, daily KRL ridership has consistently hovered around 900,000 to 1 million passengers, often peaking above 1.1 million on weekdays. This is a substantial increase from the initial years of the commuter line’s revamp. Projections suggest this number will continue to rise as urban populations expand and more people opt for public transport.
• Capacity Gap: Despite operational efficiencies, the existing fleet struggles to meet peak hour demand, leading to standing-room-only conditions and reduced comfort for passengers. The addition of 16 train sets (potentially 128-192 cars, assuming 8-12 cars per set) is expected to increase overall carrying capacity by approximately 10-15%, significantly alleviating congestion on various routes.
• Local Content Requirement: The procurement from INKA underscores Indonesia’s commitment to increasing the local content in its infrastructure projects. This not only saves foreign exchange but also builds domestic technological capabilities and creates skilled jobs.
• Infrastructure Development: Complementary investments in depot expansion, signaling system upgrades, and track improvements are essential to support an enlarged fleet. Without adequate maintenance and operational infrastructure, new trains alone cannot fully address the capacity challenge.
