Rolling stock As of 2024, KAI operated: • 462
locomotive units; • 1020
electric multiple units carriages; • 90

freight cars The company is a major customer of the local railway equipment industry,
PT Industri Kereta Api, which produces its passenger coaches, freight wagons and electric multiple units.
Locomotives KAI's diesel-electric locomotives are mostly made in the United States or Canada, diesel hydraulic locomotives are mostly made in Germany, and electric units are mostly made in Japan. AIC assembles diesel-electric TRAXX Asia Locomotives in
Surabaya,
East Java, in cooperation with
Bombardier Transportation (now
Alstom). The steam locomotive classification was directly derived from the
Japanese 1928 numbering system (which was adopted by the
wartime Japanese occupation authorities). Tank locomotives were numbered from the 10s, while tender locomotives were numbered from the 50s. Letter combinations were used for
Mallet locomotives.
Named passenger trains KAI Limited runs six classes of coaches in its various named passenger trains in Java and Sumatra, namely the Luxury/Imperial (first class), Executive (first class), Business (second class), Priority (tourist/first to second class), Economy Premium (second class) and Economy (third class) classes. Alongside regular coaches, KAI operates a number of generator, baggage/parcels and dining cars which also compose these trainsets.
Exclusive carriages and "Bali'" tourist car attached to a regular train The
kereta wisata ( "tourist carriage") is a luxury class passenger car that can be rented and attached to a regular trainset for a specific journey. The main users of these exclusive carriages are government officials, corporate boards, extended families, and groups of artists or tourists. The rental fee is about for short trips such as Jakarta–Bandung or Jakarta–Cirebon and up to for long distance Jakarta–Surabaya trips. These carriages can accommodate up to 22 passengers, or 19 passengers for "Nusantara" tourist/observation cars with a large bedroom for two. Snacks, meals, and drinks are provided free of charge in these carriages. Since the 2020s, alongside these cars, KAI has debuted tourist versions of its long distance day trains for both local and international tourists. These trains have a capacity of 20 passengers on the "Imperial" class open coach/bar cars and "Retro" class lounge and dining cars, and 30 on the "Priority" class lounge/coach cars, but are powered by regular diesels as in the regular express trains. The first such train for tourists, the
Java Priority, debuted in 2024 after more than half a century, becoming the first tourist-only service in the KAI network in Java since the 1960s. All these cars, together with the panoramic observation style cars, the 2018 design open sleeper/coach cars and the younger 16-seat compartment sleeper-chair cars (debuted 2023) all attached to regular long distance trainsets, are all operated by subsidiary firm KAI Wisata and maintained for KAI by Industri Kereta Api (INKA) Limited.
Disability carriage On 18 October 2014, KAI launched the
Jayabaya train for disabled people traveling the Pasar Senen–Surabaya–Malang route and back. The train includes two accessible carriages, which feature disability-friendly toilets, doors, and spacious areas. Similar facilities are planned for implementation on other trains.
Freight , Palembang. To support operations, Suka Cinta Station was developed from a small remote station to a larger station with coal loading facilities. The company also operates
intermodal container trains.
Library train KAI operates a library train,
Kereta Pustaka Indonesia, which houses documentation of company activities, small size assets, and books. The library train holds an exhibition for one week at a station before moving to the next.

Yogyakarta, for maintenance of diesel electric and diesel hydraulic locomotives. In Sumatra, the maintenance shops are in
Lahat Regency (South Sumatra),
Padang (West Sumatra), and
Pulubrayan (North Sumatra). Other rolling stock workshops are present in Manggarai (Jakarta),
Tegal (Central Java), and Gubeng (Surabaya, East Java). These places are used for maintenance of passenger carriages and freight wagons. A large stabling point and maintenance facility for electric multiple units are located in
Depok,
West Java.
Motive power depots are located in Medan, Padang, Padang Panjang, Kertapati, Tanjungkarang, Rangkasbitung, Cipinang (Jakarta), Bandung, Cirebon, Purwokerto, Cilacap, Kutoarjo, Semarang Poncol, Ambarawa, Yogyakarta, Solo Balapan, Madiun, Sidotopo (Surabaya), and Jember. Large areas in front of Station (formerly a motive power depot) have been used to scrap disused economy-class electric multiple units since 2013.
Safety and security Polsuska (
Indonesian:
Polisi Khusus Kereta Api, Railroad Special Police) is KAI's security unit. It is responsible for maintaining law and order, including ensuring the security of
railway stations and train passengers. Polsuska functions as a special railroad police unit that issues tickets and patrols stations to supplement the work of the
national police. Polsuska officers wear black uniforms and orange
berets pulled to the left. The unit is trained by the
Indonesian National Police and operate under the command of the Indonesian Railway Company's Directorate of Safety and Security. The
commuter lines that serve
Greater Jakarta maintain a separate security force
Petugas Keamanan Dalam (PKD). Their service uniforms are dark blue and they wear white helmets (or peaked caps). Every railway station employs
security guards to assist Polsuska in maintaining order and security. During peak travel periods, such as national holidays, Polsuska may be assisted by members of the
armed forces and
police. ==Legislation==
