Traction can also refer to the maximum tractive force between a body and a surface, as limited by available friction; when this is the case, traction is often expressed as the ratio of the maximum tractive force to the normal force and is termed the coefficient of traction (similar to coefficient of friction).
The CC203 35 locomotive, a special loco for the New Argo Jati train in 2009.. A unique modification is the wide cab version of the 2,000 hp (1,500 kW) U20C used on the 1,067 mm (3 ft 6 in) gauge Indonesian railroad and operated by PT Kereta Api Indonesia (Indonesian National Railway Company).
Meanwhile, the tractive effort of these locomotives is as much as 248 kN (starting) and 207 kN (continuous). These locomotives are equipped with GE BrightStar™ computer systems, integrated with the GE Integrated Function Display™. The CC206s have different horns from the previous GE locos in Indonesia.
The term tractive effort is often qualified as starting tractive effort, continuous tractive effort and maximum tractive effort.These terms apply to different operating conditions, but are related by common mechanical factors: input torque to the driving wheels, the wheel diameter, coefficient of friction (μ) between the driving wheels and supporting surface, and the weight applied to the ...
The most powerful locomotive of the first LKM type had a power output of 90 horsepower (90 PS). In 1954 two prototypes of the Ns 4 were built for were for export to Hungary. In 1955 18 locomotives were built for Indonesia with the type designation of Ns 4 a. There is still at least one locomotive of Type Ns 4 a in Indonesia today.
The D52 was a mainstay for this train until the end of steam operation in Indonesia. In contrast to the Java-based units, Sumatra -based D52 locomotives were used for hauling freight trains, mainly coal trains from the Tanjung Enim coal mine, now owned by the PT Bukit Asam mining company, to the coal dumping sites at Kertapati and Tarahan.
INKA Ltd was established in by the Indonesian government in May 1981 to serve as the national rail locomotive and rolling stock manufacturer for the Indonesian Railway Company (PT Kereta Api Indonesia (Persero)) in its revenue lines in the islands of Java and Sumatra and to manage the steam locomotive PJKA in Madiun which was planned to be converted into a railway infrastructure factory.
