# Kereta Api Indonesia

PT Kereta Api Indonesia (Persero) (lit. 'Indonesian Railways (State-owned) Limited', abbreviated as PT KAI or simply KAI) is a major railway operator in Indonesia and one of the public railway companies in the country. It is state-owned and pays track access charges. Its headquarters are located in Bandung, West Java. In 2019, KAI carried 429 million passengers and 47.2 million tonnes of cargo.

## History

Kereta Api Indonesia is the latest of a long line of successive state railway companies dating from Dutch colonial days. On 27 August 1863, Indonesia's first railway company was named Nederlandsch-Indische Spoorweg Maatschappij (NIS). The colonial government of Dutch-East Indies gave the concession to W. Poolman, Alex Frazer and E.H. Kol on 28 August 1862. Samarang-Tanggung (Grobogan) was its initial route. The ground breaking was in Kemijen village, Semarang by L.A.J.W. Baron Sloet van de Beele on 17 June 1864. The line opened on 10 August 1867 was Batavia (Jakarta) – Buitenzorg (Bogor) and Samarang – Vorstenlanden (Surakarta and Yogyakarta). They faced big losses and faced bankruptcy. The colonial government assisted the company by forming Staatsspoorwegen, a state-owned company on 6 April 1875. Their route stretched from Buitenzorg to Soerabaja. The private company Deli Spoorweg Maatschappij operated exclusively in North Sumatra, to transport rubber and tobacco around the Deli area.
In 1939, the total operational trackage was 4,588 kilometres (2,851 mi) (it is unclear whether dual gauge tracks were counted once or twice).
Indonesia gained independence in 1945 and has its sovereignty recognized in 1949. The various railway systems (except the Deli Railway Company) were combined into Djawatan Kereta Api Republik Indonesia (DKARI, Railways Service of the Republic of Indonesia) in 1953. Non-state railway systems in Java retained their formal existence until 1958, when all railway lines were nationalised, including the Deli in North Sumatra, thereby creating the Perusahaan Negara Kereta Api (PNKA, State Railways Corporation) on 28 September 1960. On 28 September 1970 PNKA was changed to Perusahaan Jawatan Kereta Api (PJKA, the Railway Service Corporation).
Much of the branch lines constructed in the colonial era were lifted up or abandoned in the 1980s.
Railway operations in Indonesia were at one time regulated by Act No. 13 of 1992 on Railways. This legislation stated that the government operates railways (arts. 4 and 6), delegates operations to an operating body [then the Perumka, later PT Kereta Api] (art. 6) and provides and maintains railway infrastructure (art. 8). Private companies were allowed to co-operate in operation of railways (art. 6).
On 1 August 1990, PJKA changed to Perusahaan Umum Kereta Api (Perumka, the Railways Public Corporation), and as of 1 June 1999 converted into joint-stock company PT Kereta Api (Persero) (PT KA, Indonesian Railways Company JSC). In May 2010, it became PT Kereta Api Indonesia (Persero) (PT KAI).
Electric locomotives were always a minority, and no new electric locomotives were acquired until the 1970s. However, electric multiple units have been imported since 1976 for the Jabotabek commuter urban transport, which was spun off from KAI in August 2008.
After changing the rail between Purwosari station and Wonogiri station and the bridges with R42 (37 kilometres), so line between Sangkrah station, Solo and Wonogiri became served by heavy electric diesel locomotives.
On 3 May 2011 the company trialed a cargo train from Cikarang Dry Port to Surabaya. In December, a memorandum of understanding was signed between KAI and Bombardier Transportation. The project would have established final assembly of diesel-electric TRAXX Asia Locomotives in Surabaya, East Java for export and domestic use. The plant and project appears to have been abandoned as no TRAXX plant has been built in Surabaya.
In 2012, KAI and GE Transportation signed a Memorandum of Understanding to cooperate on train services. All services are provided locally by Indonesian workers. GE runs a traction motor remanufacturing center to serve all ASEAN countries.
In 2012, Indonesian Railways allocated Rp20 billion (US$2.2 million) to restore and renovate 20 heritage sites and historical railways on Java and Sumatra.
727 kilometres (452 mi) of the northern coast area lines of Java were double tracked in May 2014, followed by the completion of a 1,000 kilometres (620 mi) double tracking project on the south coast by 2015. On 8 June 2015 the Duri-Tangerang double track project was inaugurated for KA Commuter Jabodetabek, but it can be also used for airport trains. Construction began in early 2015 to connect Cikarang Dry Port and Tanjung Priok Port to ease traffic.
The first trackage project of the Trans-Sulawesi Railway with a length of 143 kilometres from Makassar to Pare-pare was completed in 2017. The train began service in 2018 with trackage wider than in Java to accommodate more weight and speed.

## Assets

Revaluation of assets was done by the Ministry of Transportation. The company owns Rp.35 trillion ($4.1 billion) as land and Rp.22 trillion ($2.6 billion) as other assets (bridges, signals, etc.). The exact value was to be determined by the end of 2011 or 2012, based on an audit by the Ministry of Finance.

### Trackage

The company operates cape gauge (1,067 mm or 3 ft 6 in) and 1,435 mm (4 ft 8+1⁄2 in) standard gauge lines. The 1,067 mm gauge is the most common, used in Java and the majority of Sumatra, while the 1,435 mm gauge is used only in Aceh, the Trans-Sulawesi Railway, and Jabodebek LRT. The company used to operate 750 mm (2 ft 5+1⁄2 in) gauge lines in Aceh and 600 mm (1 ft 11+5⁄8 in) gauge for some tramway lines.
The total trackage laid in Indonesia was 7,583 kilometres (4,712 mi), although not all lines were in operation at the same time. The system spanned 5,042 kilometres (3,133 mi) as of 2019, with the Aceh system, most of the West Sumatra system and most former steam tram lines abandoned, but including new tracks built alongside old tracks (double tracking projects).
Many of the busiest lines are double tracked.
A Memorandum of Understanding has been signed to build railway around Bali with length of 565 km (351 miles).
The Kedungjati–Tuntang railway line, a part of the planned reactivation of Semarang–Ambarawa line, is to be the only railway in Indonesia without road crossings. It was planned to have eight flyovers and underpasses to improve safety in congested roads.

### Rolling stock

As of 2016, KAI operated:
* 420 locomotive units;
* 578 electric multiple units;
* 121 diesel multiple units;
* 1,607 passenger coaches; and
* 6,782 freight cars
The company is a major customer of the local railway equipment industry, PT Industri Kereta Api, operating passenger coaches, freight wagons and electric multiple units made by the Madiun-based company.

#### Locomotives

KAIs' diesel-electric locomotives are mostly made in the United States or Canada, while the diesel hydraulics are mostly made in Germany. Electric units are mostly Japanese-built. Local industry is capable of building both diesel and electric units. AIC assembles diesel-electric TRAXX Asia Locomotives in Surabaya, East Java with Bombardier Transportation (now Alstom since 2021).
All locomotives of the KAI (with the exception of steam locomotives) are diesel. Most new locomotives use diesel-electric transmission, while shunters and older locomotives have hydraulic transmission. More than 400 locomotives are documented, but the tally of operational locomotives is smaller.
Based on Minister of Transportation's Regulation No. 45 of 2010, locomotives are required to use a combination of letters and numbers for designations. A letter or a combination of letters denote the wheel arrangement (currently there are C, D, BB and CC types), and a three-digit number denotes the class (2xx for classes with electric transmission and 3xx for classes with hydraulic or mechanical transmission), starting from 0. A two-digit number shows the year of operations, and two- or three-digit after the year shows the running number.
Examples
* CC 206 13 31: The 7th generation of diesel-electric Co'Co' locomotives, entered service in 2013, and have a running number 31.
* CC 201 77 01$^R$: The 2nd generation of diesel-electric Co'Co' locomotives, entered service in 1977, and have a running number 01 and has been repowered.
* BB 304 84 07$^R$: The 5th generation of diesel-hydraulic B'B' locomotives, entered service 1984, and have a running number 07 and has been repowered.
The steam locomotive classification was directly derived from the Japanese 1928 numbering system (it was adopted by the wartime Japanese occupation authorities). Tank locomotives were numbered from the 10s, while tender locomotives from the 50s. Letter combinations were used for articulated locomotives (Mallets).

#### Named passenger trains

KAI runs three classes of named passenger trains on Java: Executive class (1st class), Business class (2nd class), and Economy class (3rd class).

#### Exclusive carriages

The "exclusive carriage" is a luxury passenger carriage that can be rented and attached to a regular train for a specific journey. Exclusive carriages are known as kereta wisata ("tourist carriage"). 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 Rp 15,000,000 for short trips such as Jakarta–Bandung or Jakarta–Cirebon and up to Rp 27,000,000 for Jakarta–Surabaya trips. The carriages can accommodate up to 22 passengers, or 19 passengers for "Nusantara" carriage with a queen bed. Snacks, meals and drinks are provided for free.

#### 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 contains two disability carriages, which include accessible toilets, doors and spacious areas. It is planned to be implemented on other trains.

#### Freight

KAI operated coal trains under partnership with Bukit Asam (PTBA) in Southern Sumatra. The coal were transported from Tanjung Enim in South Sumatra to Tarahan Rotary Car Dumper in Lampung, which were then shipped to Java. Other service which was operated under partnership with PTBA transports coal from Tanjung Enim to Kertapati Apron Feeder in Palembang. After that, the coal will be transported using barges for export and domestic supply.
KAI also made partnership with several private coal mining companies in South Sumatra. The first private coal train (Baraswasta) was launched in 2011 from Suka Cinta in Lahat to Kertapati in Palembang. To support operational, Suka Cinta station which was previously just a small remote station was developed to a larger station with coal loading facilities.
The company also operated intermodal container trains. In comparison, trucks and flatbeds can only carry 1.5 trip per day, while a train can carry 40 TEUs (Twenty-foot Equivalent Units) per trip.

#### Library train

KAI operates a library train (Kereta Pustaka Indonesia) that documents company activities, small size assets and books. The library train holds an exhibition for one week in one station and then moves to another.

### Depot and facilities

In Java, KAI's main diesel workshop is located in Pengok, Special Region of 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 Purwakarta station (formerly a motive power depot) have been used for scrapping of the disused economy class electric multiple units since 2013.

### Safety and security

Polsuska (Indonesian: Polisi Khusus Kereta Api or Railroad Special Police) is KAI's security unit. Polsuska works as a special railroad police that is charged with issuing tickets and patrolling stations to supplement the work of the national police. Polsuska has responsibilities relating to law and order including security of railway stations and train users. Polsuska officers wear black uniforms and orange berets pulled to the left. Polsuska is trained by the Indonesian National Police. Polsuska is 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). They are categorized as security guards. Their service uniforms are dark blue and they wear white helmets (or peaked caps). They are not part of Polsuska.
Every railway station employs security guards to assist Polsuska in maintaining order and security. During peak days such as national holidays, Polsuska may be assisted by members from the armed forces and police.

## Legislation

Act No. 23 of 2007 took effect on 25 April 2007. In this law, track maintenance is more directly handled by the government via the Directorate General of Railways, under the Ministry of Transportation.

## Subsidiaries

KAI operates multiple subsidiary businesses.
The Railway Employee Welfare Center Foundation (Yayasan Pusaka), one of PNKA's foundations, established PT Karya Pusaka (founded on 5 December 1967) and renamed it PT Pusaka Nusantara on 18 April 1970. Pusaka focuses on restoration, outsourcing, and cleanliness of train infrastructure and facilities.
The first subsidiary of PT Kereta Api was Reska Multi Usaha [id]. This company focuses on business services to support railroad operations, such as restoration, parking, cleanliness on the train, restaurants and cafes, train washing, and comfort support. The company was formed on 2 July 2003. Reska owns the LoKo trademark, a restaurant chain with the theme of rail transportation that operates many station restaurants.
Jabotabek Urban Transport Division manages electrified commuter service in Jakarta metropolitan area (currently KRL Commuterline) as a subsidiary under the name PT Kereta Commuter Indonesia (KCI).
Kereta Api Pariwisata (branded as KA Wisata, formerly IndoRailTour) provides rail tourism services. KA Properti Manajemen (KAPM) provides property management. Kereta Api Logistik (Kalog) provides logistics. A KAI joint venture with Angkasa Pura II operates an airport train service, under the name Railink [id] via the Kualanamu Airport Rail Link train.
PT KAI is in a consortium with Wijaya Karya [id] (Wika), Perkebunan Nusantara VIII [id] (PTPN VIII), and Jasa Marga, under the name Pilar Sinergi BUMN Indonesia for the Jakarta–Bandung high-speed train project operated by Kereta Cepat Indonesia China (KCIC).
Pursuant to Indonesia's "two shareholder minimum" on limited companies, Yayasan Pusaka owns less than one percent of shares in KAI's consolidated subsidiaries except KAI Bandara and PSBI/KCIC.

### Rail replacement through transport (Angkutan terusan)

PT Kereta Api Indonesia (KAI) through transportation is a service provided to facilitate passenger travel, both those who are going to the station and those who are going to continue their journey after getting off the train. Some of PT KAI's through transportation routes include:

#### Semarang to Demak, Kudus, and Pati

This through transportation serves a round-trip route from Semarang Tawang Station or Poncol Station to the three cities. This through transportation uses Isuzu Elf which is equipped with AC, reclining seats, entertainment, and USB chargers.

#### Purwokerto to Wonosobo, Banjarnegara, and Purbalingga

This through transportation serves the route from Purwokerto Station to the three areas, and vice versa. This through transportation uses an Elf fleet with a capacity of 12 seats.

## Former Subsidiaries
### Dinas Pelayaran

Dinas Pelayaran (Sailing Services) is one of the divisions of Railway Bureau Company (PJKA) which operates in the field of water transportation. This service was formed in the 1950s after the merger of the Republic of Indonesia Railway Department (DKARI) and the Staatsspoorwegen en Verenigde Spoorwegbedrijf (SS/VS) to become the Railway Department (DKA)—formed to serve passengers who would cross the Madura Strait, Bali Strait, Sunda Strait, and Sunda River. Ogan]], and Musi River. The crossing service provided is continuous transportation for train passengers who wish to continue their journey by crossing the rivers or straits served. In 1989 PJKA dissolved this service along with the formation of PT ASDP. Other reasons, namely the construction of the Ampera Bridge in Palembang and the decommissioning of the railway line on Madura Island which made the fate of this division even more gloomy.

#### History

Along with the merger of DKARI and SS/VS into the Railway Service (DKA) in the early 1950s, several ferries and tugboats or pilot boats were also provided to DKA. Ferries were specifically for canal transportation that served passengers, goods, and vehicles that would cross the Sunda Strait, Bali Strait, and Madura Strait, as well as the Musi River and Ogan River. While tugboats/pilot boats were used to guide large ships entering and leaving the port.
At that time, DKA received the handover of the railway station in the port complex along with its dock which had originally been managed by railway employees such as Merak Station with Merak Port, Long Station with Long Port, Ujung Station with a pontoon dock, Kamal Station with a pontoon dock, and Banyuwangi Lama Station which was integrated with DKA's feeder bus and crossed by DKA's ferry to Gilimanuk Port, Bali.
The operation of the Railway Service's ferry as a connecting transport has many benefits and has successfully attracted many enthusiasts. The Railway Department provides shipping with several routes, such as Merak Port-Long Port and the Musi River crossing to support the Jakarta-Palembang connection via train, Ujung Station pontoon pier–Kamal Station pontoon pier to support the connectivity of the Surabaya railway line with the Madura railway line and the mobility of its residents, and Gilimanuk Port-Banyuwangi (former Boom Port). On the Gilimanuk Port-Banyuwangi shipping route, the Railway Department also provides feeder bus services. The connectivity of Banyuwangi with Bali Island greatly supports the creation of connectivity and social mobility in the region, especially in the tourism sector.
In addition to ferries, the Railway Service also has a number of tugboats that are on duty at the port/pier near Kertapati Station to guide barges from Palembang Port to the port/pier Kertapati Station. These tugboats are under the inspection of the South Sumatra Exploitation Leadership.
Inter-island crossing activities in Indonesia have been pioneered by the Government in this case the Railway Service (DKA, PNKA, PJKA). Historical facts record that the ship Taliwang was one of the first connections from the Merak -Panjang route in 1952.
In 1960, the Dutch Government provided a grant to the Indonesian Government in this case the Railway Department (DKA) in the form of three 2,314 GT ships imported directly from the Netherlands, namely KM Halimun C/S PKMH, and KM Krakatau in 1961, and KM Bukit Barisan in 1962. Unfortunately, KM Bukit Barisan caught fire and sank while unloading at Pelabuhan Merak in 1977. The three ships were built at the Zaandam Shipyard with a Werkspoor 750 DK × 2 production engine, used to serve crossings from Pelabuhan Panjang (Lampung) to Merak Port (West Java) which is currently part of the Banten region.
The main service on this route is only passengers and goods, if there are vehicles crossing, they will be transported to the deck of the ship using a crane, the number of which is also very limited considering that the three ships are not equipped with a ramp door. The expansion and development of Ports III, IV, and V Merak operated by ASDP is currently a silent witness (formerly) was a port that was once used by Perusahaan Jawatan Api (PJKA) for loading and unloading activities of its fleet of ships.

#### Services

Here are the services that have been operated.
| Location | Crossing | Fleet | Description |
| Sunda Strait | Merak-Panjang | KT Terate KT Seroja KT Anantasena KM Halimun KM Bukit Barisan KM Krakatau KM Karimun | The assets that still exist today are managed by PT ASDP Indonesia Ferry and PT Dharma Lautan Utama |

| Musi River and Ogan River | Palembang-Kertapati | K.T. Bhakti KM Reni KM Cendrawasih KM Srigunting | The assets that still exist today are managed by PT ASDP Indonesia Ferry and PT Dharma Lautan Utama |

#### Closure

Over time and changing regulations, PJKA stopped operating all of its fleet of ships and handed them over to be operated and managed by PT ASDP in 1989. Furthermore, PJKA only focused on its main business, which was managing trains.

### PT. Rama Restorka (PO Mutiara)

In the 1990s, PO Mutiara (PT Rama Restorka) was used a bus as a continuing transportation for train passengers from Banyuwangi Baru Train Station (Ketapang) to Ubung Bus Terminal Denpasar and the Perumka representative office on Jl. Teuku Umar Denpasar, Bali.
