PT Industri Kereta Api (Persero) (translated as: The Indonesian Rolling Stock Manufacturing Corporation, Ltd.), abbreviated as Inka or INKA, is a government-owned corporation which was formed on 19 August 1981 as the successor of Balai Yasa Lokomotif Uap (steam locomotive workshop) owned by Perusahaan Jawatan Kereta Api (now PT Kereta Api Indonesia) in Madiun, East Java, Indonesia. As of mid-1970s, steam locomotives are no longer used in Indonesia and the defunct workshop was then converted into a railway rolling stock manufacturer.


The business activity of PT Industri Kereta Api Indonesia is growing from basic product to the higher value added product and services in railway and transportation business. The mission on business and technology competitiveness creation in railway and transportation products is focussed to dominate domestic market and to win competition in ASEAN region and developing countries.

High demand intercity railway is increasing in the high density region in the archipelago countries. New passenger coaches were introduced to capture the niche market with quality of services. In the beginning, value migration was created to absorb middle class passenger mobility. The next step development is prepared to adapt newest technology for diesel electric railcar on the medium distance railway corridor.

Those new technology is upgraded from the development of commuter electric railcar using light weight stainless steel carbody and modern AC traction control with IGBT VVVF inverter. Commuter railcar is the best solution for public urban transport. Based on experiences in commuter services, the modern electric railcar will be soon developed to more reliable design for future mass rapid transit.

In the developing countries, railway is expected to be backbone of land transportation. The large scale mining and industry commodities are better carried by bulk rail wagon. Various design of freight wagon can adapt the special demand of handling and higher capacity such as 18 ton axle load in the coal and pulp transportation. On the other hand, the modern container flat wagon is designed for speed up 100 km/h and light weight requirement.

The new railway line and double track projects in developing countries are increasing to cope the potential demand of goods transport as well as to improve line capacity. High quality hopper wagon and multi purpose track maintenance car is usually required in small lot. New approach on mutual collaboration with railway consultant and civil contractor will overcome an efficient turnkey project especially for plantation and mining area.


Without much publicity, PT. INKA has been producing a variety of locomotive, train, and car. Many of them are made in cooperation, there is also a body of a car and they were over. Some products even have been exported to foreign countries. With stiff competition between rail and air transportation in recent years, PT Inka is facing an increasingly tough domestic market.

In addition, PT INKA is also pioneering the production of a national car called GEA (short for Gulirkan Energi Alternatif) and a prototype was created in 2008.[1] In 2009, GEA began using the machine developed by BPPT, Rusnas, after previously using Chinese machinery. Carburator is the only imported component in the 2009 prototype.

PT. INKA also supply Compressed Natural Gas-powered (CNG) buses for TransJakarta, mainly known as the name brand Inobus (abbreviated as Innovation Bus)
