Kereta Api Indonesia

The company currently operates two types of railways, Cape gauge (1,067 mm (3 ft 6 in)) and standard gauge (1,435 mm (4 ft 8+1⁄2 in)). The 1,067 mm gauge is most common in Java and all regional divisions of Sumatra, while the railway uses 1,435 mm gauge. Historically, the company had operated 600 mm gauge and 750 mm gauge for some tramway lines.[3]

The total number of trackage laid in Indonesia was 7,583 kilometres (4,712 mi), although not all lines were in operation at the same time. 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). The present extent of the system is now 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).

Much of the branch lines constructed in the colonial era have been lifted up or abandoned in the 1980s. No major railway construction has since taken place; however, many of the busiest lines have been double tracked. 727 kilometres (452 mi) of the northern coast area lines of Java was double tracked in May 2014,[16] followed by the completion of a 1,000 kilometres (620 mi) double tracking project on the south coast by 2015.[17][18] 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.[19]

Significant projects being considered include:

• Quadrapling Manggarai-Cikarang line. The project will be divided into 2 segments: Manggarai-Bekasi, 15 kilometres long and scheduled to be finished in 2016 and Bekasi-Cikarang, 17 kilometres long scheduled to be finished in 2017[20]
• Airport line to the Sukarno-Hatta International Airport. A 33 kilometer line from Manggarai, Dukuh Atas in Sudirman, Tanah Abang, Angke, and Pluit and along the airport toll road to the airport. The cost was projected to be US$1.13 billion. Construction began 2012 and originally projected to be completed at 2014; though the completion of the railway had been delayed to 2017, when the train commenced operation.
• Rebuilding of the Aceh railway, with assistance from the French railway company SNCF.
• Building new 15-kilometres-long track between Cibungur and Tanjungrasa station. This shortcut will ensure trains from Bandung to Semarang do not need to go through Cikampek station.[21]

Future expansion plans of the railway will include linking of existing railway lines in Sumatra from Aceh to Lampung via both west and east coasts of the island. Railway lines are also planned to be built on the currently railway-free islands of Kalimantan[22] and Sulawesi.[23] A Memorandum of Understanding has been signed to build railway around Bali with length of 565 kilometers.[24] Nowadays, the first trackage project of the Trans-Sulawesi Railway with a length of 143 kilometres from Makassar to Pare-pare was initiated with 30 kilometres of land acquisitions, and initial construction began in June 2015, with 70 kilometres built in 2016 and the remaining 43 kilometres built in 2017. The train began service in 2018 with trackage wider than in Java to accommodate more weight and speed. The schedule for Pare-pare to Manado trackage will be completed in 5 years after it.[25]

There are also plans to reactivate non-operational railway lines in West Java, such as the Bandung-Ciwidey line, intended to ease road traffic congestion; and the Rancaekek-Tanjung Sari line. Four other non-operational lines are still in consideration.[26]

The Kedungjati-Tuntang trackage, a part of the Semarang-Ambarawa reactivated trackage, is the only railway in Indonesia without road crossings. It has 8 flyovers and underpasses to improve safety in congested traffic roads.[27]

As of 2016, KAI operates:

• 420 locomotive units;
• 578 electric multiple units;
• 121 diesel multiple units;
• 1,607 passenger coaches; and
• 6,782 freight cars[28]

The company is a major customer of the local railway equipment industry, PT Industri Kereta Api, using passenger coaches, freight wagons and electric multiple units made by the Madiun-based company.

KAIs' diesel-electric locomotives are mostly made in United States or Canada, while the diesel hydraulics are mostly German. Electric multiple units are mostly Japanese-built. Local industry is capable of building multiple units, both diesel and electric.

All locomotives of the KAI (with the exception of Steam locomotives for railway tours in Ambarawa) are diesel-engined. Most new locomotives use diesel-electric transmission, while older and lighter ones have hydraulic transmission. More than 400 locomotives (see below) are documented, but the actual number of operational locomotives is smaller. A recent source mentioned that the company have had 409 units of diesel locomotives. The oldest diesel locomotive in the system dates from 1953.

Based on Minister of Transportation's Regulation No. 45 of 2010, all of locomotives are required to use a combination of letters and numbers. A letter or a combination of letters is used to denote the wheel arrangement (currently there are C, D, BB and CC types), and a three-digit number is used to denote 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, has operated since 2013, and have a running number 31.
• CC 201 77 01^R: The 2nd generation of diesel-electric Co'Co' locomotives, has operated since 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, has operated since 1984, and have a running number 07 and has been repowered.

The steam locomotive classification was directly derived from Japanese practice (it was first 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 (in the case of Indonesia these were Mallets).

Electric locomotives in Indonesia had always been a minority, and no new electric locomotives had been acquired in the last 70 years. However, electric multiple units have been imported from Japan and elsewhere since 1976. These are operated by the Jabotabek commuter urban transport division of the KAI, which has been spun off in August 2008.

May 2011: After changing the rail between Purwosari station and Wonogiri station and also the bridges with R42 (37 kilometres), so line between Sangkrah station, Solo and Wonogiri will be served by heavy electric diesel locomotives.[29]

KAI diesel locomotive classes

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

The "exclusive wagon" is a luxury train car rentable for a certain route, and attached to a regular train. Exclusive wagons are also known as kereta wisata ("tourist wagon"). The main users of these exclusive wagons are the president, vice-president, corporate boards, big extended families, and groups of artists or tourists. The rental fee of a car 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. All cars can accommodate 22 passengers, and only 19 passengers for Nusantara cars with a queen bed. Snacks, meals and drinks are provided for free.[30] KAI recommends advanced booking with payment due to high demand.

On 18 October 2014, KAI launched the Jayabaya train with route Pasar Senen-Surabaya-Malang and back. The train contains two disability wagons, which include toilets for disabled persons, wide doors and spacious areas for wheelchairs. It will be implemented on other trains gradually.[31][32]

To anticipate a steady number of passengers, KAI has boosted cargo deliveries. On 3 May 2011 the company trialed the line from Cikarang Dry Port to Surabaya.

KAI and Danone Indonesia have made an agreement to carry Danone's water in 2013 to Jakarta. KAI will replace the track from R33 to R54 between Cicurug and Sukabumi with length 20 kilometres, spending Rp2 trillion ($222 million). One cargo train can replace 40 to 60 trucks.[33] In addition, the company serves trains of coal in South Sumatra.

The government has tasked KAI with connecting Cikarang Dry Port and Tanjung Priok Port to ease heavy traffic between two locations. Construction began in early 2015. Trucks and flatbeds can only run 1.5 trip per day, while a train can carry 40 TEUs (Twenty-foot Equivalent Units) per trip.[34]

To popularise their business, KAI launched the library wagon (Kereta Pustaka Indonesia) which displays documented company activities, small size assets and books. The library wagon staff holds an exhibition for one week in one station and then moves to other station.[35]

In front of KAI Locomotives and Rolling Stocks Workshop in Yogyakarta.

In Java, KAI located its main diesel workshop in Pengok, Special Region of Yogyakarta for maintenance of both diesel electric and diesel hydraulic locomotives. The separate systems in Sumatra have their shops in Lahat Regency (South Sumatra), Padang (West Sumatra) and Pulubrayan (North Sumatra).

Other maintenance facilities are present in Manggarai (Jakarta), Tegal (Central Java) and Gubeng (Surabaya, East Java). These are used to repair coaches and wagons.

A large stabling point and maintenance facilities for electric rail cars has been constructed in Depok, West Java.

Motive power depots are located in Medan, Tebing Tinggi, Padang, Padang Panjang, Kertapati, Tanjungkarang, Rangkasbitung, Tanahabang (Jakarta), Cipinang (Jakarta), Bandung, Banjar, Cibatu, Cirebon, Purwokerto, Cilacap, Kutoarjo, Semarang Poncol, Yogyakarta, Solo Balapan, Cepu, Madiun, Sidotopo (Surabaya), and Jember.

Large areas in front of Purwakarta station (formerly a motive power depot) have been used for scrapping of the unused economy class electric multiple units since 2013.

Polsuska (Indonesian: Polisi Khusus Kereta Api or Railroad Special Police) is a law enforcement unit under the auspices of the KAI. Polsuska in its role as a special railroad police is tasked with: applying sanctions in accordance with legislation and implement security, preventing crime, and preventing non-judicial actions within the scope of the Indonesian railways as a partner of the national police. Polsuska has responsibilities relating to law and order including security of railway stations and train users.[36] Polsuska officers wear black as their uniform and wear orange berets pulled to the left. Polsuska is trained by but not part of the Indonesian National Police. Polsuska is under the command of the Indonesian Railway Company's Directorate of Safety and Security.

The Commuter Lines which serve Greater Jakarta maintain their own security force who are categorized as security guards. Their service uniforms are dark blue and they wear white helmets (or peaked caps) and are known as (Petugas Keamanan Dalam/PKD). These are not part of Polsuska.

Every railway station in Indonesia also operates several security guards to assist Polsuska in the field of law and order including security. During peak seasons such as during the last days of Ramadan and other national holidays, Polsuska may be assisted by members from the armed forces and police to provide an additional security presence within the KAI system.
