The GE CM20EMP diesel-electric locomotives (also known as CC206 in Indonesia) are owned by PT Kereta Api (Indonesian Railways Co.) and built by GE Rail. The GE CM20EMPs are export locomotives that were originally used for freight trains, but which can now haul passenger trains (i.e. executive class, business class, or economy class). The locomotives are still in operation and operate along the Java main line. They have two drivers cabins.
Contents
Started operations in 2013, the CC206 locomotives are now Indonesian Railway's main workhorses for hauling express passenger and heavy freight trains in Java and Southern Sumatra.
History
The first double cabin locomotives were the GE CM20EMP's predecessors, such as CC200s (Alco-GE UM 106T), BB301s and BB304s (Krupp M1500BB), and BB305s (built by CFD). While they were once used for express passenger train duty, they are now mostly operated as switchers and haulers of local trains, or have been withdrawn.
Between 2000 and 2010 the Indonesian Railways Co. decided to buy more powerful, computerized diesel-electric locomotives such as previously owned CC204s (C20EMP locomotives). In 2010, the company decided to buy new diesel-electric locomotives to add to its rolling stock and replace old locomotives.
By September 2012 the company had bought 100 locomotives of the CM20EMP type and these have been operated since 2013. The locomotives were supplied without bogies and the bogies were assembled by Barata Indonesia. When the ship that carried the locomotives arrived in Tanjung Priok Port, the locomotives were brought to Indonesian Railways Locomotive Workshop in Jogjakarta.
Additional 50 locomotives were ordered in 2014, with the first 10 locos began to arrive in August 2015.
Body
The CM20EMPs were made when Indonesian Railways Co. needed a double-cab locomotive. The cab and body are similar to the British Rail Class 70 (GE PowerHaul series), but the front windows are like the Indonesian GE U20Cs of class CC203. The headlights and cab doors are like another (unspecified) Indonesian U20C.
Engines, specifications, and electronic devices
These locomotives use a new version of the GE 7FDL-8 engine that meets the same emission standards as the GE Dash 9 Series locomotives. The power output of CM20EMPs is 2,250 horsepower, equal to that of EMD G26, and 100 hp more than the 2,150 hp CC203s/GE U20C. 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. While its predecessors use Wabco AA2, the CC206 locomotives use Nathan P3.
One unit of CC206 locomotive could haul up to 16 passenger cars or 30 freight cars.
Allocations
All the CC206s are operated in Java and are allocated to all motive power depots except Madiun and Jember.Most of the locomotives delivered in 2015 will also be based at Tanjung Karang in Southern Sumatera.
