Industri Kereta Api

PT Industri Kereta Api, commonly known as INKA, is Indonesia's state-owned rolling-stock manufacturer. Established in 1981, the company was created to develop domestic railway-manufacturing capability and to transform the former railway workshop in Madiun, East Java, into an industrial production facility. Its principal customers have included Indonesia's national railway operator and government transport agencies, while its export customers have included railway organizations and transport companies in Malaysia, Thailand, Bangladesh, the Philippines, Australia, and New Zealand. INKA's core business covers the design, manufacture, refurbishment, and maintenance of railway vehicles. Its portfolio includes passenger coaches, economy and executive-class cars, electric multiple units, diesel multiple units, locomotives, freight wagons, container and flat wagons, rail buses, airport railway vehicles, light-rail vehicles, and inspection or specialized railway equipment. The company has been an important supplier to the Indonesian railway system since the 1980s, supporting the expansion and modernization of intercity, commuter, airport, and urban rail services across Java, Sumatra, and other Indonesian regions. The company's early development focused on conventional passenger coaches and freight cars. It later expanded into electric multiple units through licensed cooperation with Japanese manufacturers and subsequently developed greater local production capability. During the 1990s, INKA broadened its engineering base through projects involving long-distance trainsets and locomotives, including cooperation with General Electric. Its export program also grew during that decade, beginning with freight wagons for Malaysia and later extending to Thailand and other markets. INKA has worked with international technology and manufacturing partners while progressively increasing its own design and production capabilities. Its railway products have incorporated steel and stainless-steel car bodies, modern traction systems, air-conditioning equipment, and configurations adapted to local operating conditions. The company has also produced rolling stock for Indonesia's airport rail link, Palembang LRT, Jabodebek LRT, and national commuter services. It has supplied diesel multiple units and rail buses for regional services and has produced specialized freight equipment for coal, containers, and other cargo. Although railway vehicles remain its defining business, INKA has pursued adjacent transport activities. These have included the proposed GEA small vehicle, CNG-powered Inobus buses for urban public transport, the Kancil compact vehicle project, and electric-bus development. These initiatives reflect an effort to apply the company's manufacturing and engineering capabilities beyond rail, although the available reference material does not establish all of these activities as continuing major businesses. INKA operates manufacturing facilities in Madiun and Banyuwangi. In 2020, INKA, Indonesia's national railway operator KAI, and Stadler Rail were reported to have planned a Banyuwangi facility for crash, tilt, and rollover testing in accordance with International Union of Railways standards. The company's more recent work has included additional commuter rolling stock for Indonesia, passenger and freight vehicles for overseas customers, and continuing development of locally produced railway and electric-transport products. Ownership and governance remain associated with the Indonesian state; the available reference material identifies the Indonesian government as the majority owner through Danantara but does not provide a complete current corporate ownership schedule.

INKA was established by the Indonesian government in May 1981 as part of a national strategy to create domestic railway-manufacturing capacity. Its formation involved the transfer of management of a railway workshop previously operated by PJKA, the predecessor of Indonesia's national railway operator, in Madiun, East Java. The formal workshop handover took place on 29 August 1981. The site was subsequently developed from a maintenance-oriented facility into a manufacturer capable of producing complete rolling stock. In 1982, INKA began building passenger coaches for the Indonesian railway network and produced an Indonesian-made enclosed box wagon. By 1985, it was manufacturing steel economy and executive passenger coaches, both with and without air conditioning. These products established the company as a significant domestic supplier and gave it a base for more technically demanding projects. INKA entered electric multiple-unit production in 1987 by assembling Rheostatic EMUs under license through cooperation with a Japanese consortium led by Nippon Sharyo. Full production of Indonesian-made EMUs followed in 1994 through cooperation involving BN-Holec. During the same period, the company expanded its product range into long-distance trainsets. It developed trainsets for the Argo Bromo and Argo Gede services in 1995 and produced further Argo Bromo Anggrek trainsets in 1997. International work became an increasingly important part of the company's development. INKA exported freight wagons to Malaysia in 1991 and supplied hopper wagons to Thailand in 1998. In 1996, cooperation with General Electric through PT GE Lokomotif Indonesia supported locomotive production, including locomotives exported to the Philippines. The company also exported train-car bodies and related structures to Australia in 2004 and supplied passenger coaches to Bangladesh in 2006. A larger Bangladesh order followed in 2016. The company continued to diversify its Indonesian railway portfolio in the 2000s. It introduced the EA201 electric multiple-unit series for the KRL commuter system in 2001, developed regional rail buses such as Kertalaya and Batara Kresna, and began diesel multiple-unit production in 2007. Its projects also included economy-class air-conditioned trainsets, GE C20EMP locomotives, freight wagons for coal and container traffic, and specialized railway equipment. During the 2010s, INKA became involved in several prominent Indonesian transport programs. It supplied vehicles for the Soekarno-Hatta Airport Rail Link and produced light-rail vehicles for Palembang. It subsequently completed the first Jabodebek LRT series. The company also introduced I-COND train air-conditioning equipment and expanded into buses, including CNG-powered Inobus products and the E-Inobus electric-bus concept. INKA's railway activities continued to include international projects. Its reported work for the Philippines included PNR 8000- and 8100-class diesel multiple units, PNR 8300-class coaches, and CC300 diesel-hydraulic locomotives. In 2020, INKA, KAI, and Stadler Rail were reported to be establishing a Banyuwangi facility for rolling-stock crash, tilt, and rollover testing under International Union of Railways standards. In 2023, INKA produced 133 flat wagons for KiwiRail in New Zealand. A later commuter project listed in the reference material is the iE305 series for KAI Commuter in 2025, while an underframe project involving GE-UGL C44 ESACi was listed for 2026. INKA has operated manufacturing facilities in Madiun and Banyuwangi. Its principal role remains the design, production, refurbishment, and support of railway vehicles for Indonesia and selected overseas customers. The company has also explored automotive and bus manufacturing, including a proposed GEA national-car project and the Kancil small vehicle, but railway rolling stock remains its defining business. The available reference material does not identify current individual executives or provide a complete current ownership breakdown. It describes INKA as state-owned and identifies the Indonesian government as the majority owner through Danantara.
