D52 Locomotive
The D52 Series locomotive was a multi-purpose steam locomotive operated by the Department of Railways of the Republic of Indonesia (Djawatan Kereta Api or DKA). It was the only type of main-line steam locomotive ordered by Indonesia following its declaration of independence.
Following the post-colonization period, the Indonesian government implemented a policy to nationalize Dutch companies operating in the country. Among them was Staatsspoorwegen (SS), the state-owned railway company of the Dutch East Indies. This entity was subsequently renamed Djawatan Kereta Api (DKA).
DKA inherited a fleet of locomotives, passenger cars, and freight wagons that were aging, with many damaged due to the war. To modernize its rolling stock, DKA ordered new locomotives, passenger cars, and freight wagons from various overseas manufacturers. One of the models ordered was the D52 steam locomotive. A total of 100 units of these 2-8-2 wheel arrangement steam locomotives were ordered by the Indonesian government. All of them were manufactured by Fried Krupp in Essen, Germany, starting in 1950.
In Java, the main function of the D52 locomotive focused heavily on passenger services rather than freight transport. Some communities even idolized this locomotive for its reliability in carrying passengers to various destinations. A notable example was its service on the Madiun–Kertosono route operating as the Rapih Dhoho train. Meanwhile, in South Sumatra, this locomotive served primarily in freight transport, specifically for hauling coal trains.
The D52 Series locomotives were distributed across eight locomotive depots in Java and Sumatra, namely:
Jatinegara (22 units)
Cirebon (15 units)
Banjar (6 units)
Kutoarjo (3 units)
Yogyakarta (16 units)
Madiun (15 units)
Sidotopo (13 units)
Kertapati (10 units)
Some people often compare this locomotive to the Baureihe 41 locomotive owned by the German Federal Railway (Deutsche Bundesbahn), which was built by the same manufacturer during the same era. The D52 featured distinct characteristic German-built locomotive features, such as small smoke deflectors, a standard boiler, and several other technical details.
The D52 could easily be considered the most modern steam locomotive ever owned by Indonesia. With large driving wheels measuring 1,503 mm in diameter, this locomotive was engineered to reach a maximum speed of up to 90 km/h—a speed rarely achieved at the time. This made the D52 exceptionally well-suited for pulling express passenger and freight trains across flat lowlands, though it performed poorly on mountainous routes (particularly in West Java) due to its tendency to run at high speeds.

Additionally, this locomotive featured a very high steam pressure of 16 kg/cm², exceeding even that of Mallet locomotives such as the DD52. Upon initial delivery, the D52 locomotives operated on two types of fuel. Units numbered D52001 to D52050 ran on coal, while the remaining units utilized residual oil. Later, between 1956 and 1965, a total of 21 coal-burning D52 locomotives were converted to oil-burning units. The conversion work was carried out by the Madiun Railway Workshop (Balai Yasa Madiun), which today has transformed into PT INKA (Persero). A total of 29 locomotives remained unconverted, ten of which were shipped to Sumatra. Today, only one D52 locomotive remains preserved: unit number D52099, located at the TMII Transportation Museum in Jakarta.
