The GE CM20EMP diesel-electric locomotives are owned by PT Kereta Api and built by GE Rail. The GE CM20EMPs are multipurpose locomotives, not only for hauling passenger trains, but also freight trains. The locomotives' operation have started in 2013, and become Indonesian Railway's main workhorses for hauling trains. These locomotives are operated along the Java main line for hauling freight and passenger train, and along South-Sumatra and Lampung Line for hauling freights. They are double-cabin, and the most active double-cabin locomotives in Indonesia.
History
The first double cabin locomotives were the GE CM20EMP's predecessors, such as CC200s, BB301s and BB304s, and BB305s. 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for express passenger train duty, they are now mostly operated as switchers and haulers of local trains, or have been withdrawn.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. But, with the increasing cost of maintenance, parts, fuel and workers, caused by aging and inefficient locomotives, in 2010, the company decided to buy new diesel-electric locomotives to be added to its rolling stock and replace some aging locomotives. But, due to the latest rule from Indonesia Government's Ministry of Transportation, every new locomotive should have no 'long-hood' position, to decrease the number of accidents. This is related to limit sight of the engineer when the locomotives move on long-hood position. 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 Pengok, Yogyakarta, to be assembled with bogies from barata, and complete their dynamics and statics test. Additional 50 locomotives were ordered in 2014, with the first-39-locos arriving on 14 August 2015, and directly be brought to Pengok, Yogyakarta. After test, 28 locomotives numbered from CC 206 112 till CC 206 139 were transferred to Kertapati, South Sumatra by Panjang port, to haul coal trains in south Sumatra. The last-11-locos arrived in Tanjung Priok Port on 14 July 2016. Same as before, the locomotives were brought to Pengok, Yogyakarta, and start the same process as before. after test, the locomotives were transferred to south Sumatra again, to fulfill the lack of locomotives' need for coal trains.
Features
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, but the front windows are like the Indonesian GE U20Cs of class CC203. The headlights and cab doors are like another Indonesian U20C.
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 and 207 kN. 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
Some of CC206s are operated in Java and are allocated to all motive power depots except Madiun and Jember.. CC 206 numbered from 01 till 11 are operated in Java, While the rest of CC 206 which arrived in 2015 and which were arrived in 2016 are now operated in South Sumatra, and allocated to motive power depot Kertapati, Palembang.
Accidents
On 12 September 2013, a conflagration destroyed a residence settlement, at Malang. As a consequence, the locomotive numbered CC206 13 16 was burnt. The witness said that the fire started in a house, where someone was cooking and spread from there. After that, the fire flamed and licked a Honda Supra motorcycle parked 2 metres from the stove. Then, the fire burnt all of the kitchen. Because the kitchen's distance was just 2 metres from the rail that headed to Pertamina depot, the fire also burnt the CC206 13 16 that was shunting an oil train. The locomotive was heavily damaged on its A-side. All the victims were injured on their feet and faces.
On 4 April 2014, at 18:30 West Indonesian Time, the Malabar train was derailed at Tasikmalaya, West Java due to a landslide. Finally, the two executive class coaches numbered K1 0 67 27 and K1 0 67 22 and the locomotive numbered CC206 13 55 jumped off completely from the rail. Because of heavy mountainous terrain and inaccessible location, the evacuation of CC206 13 55 was obstructed.
On 4 May 2014, the locomotive numbered CC206 13 69 and a power car that hauled Bogowonto train was derailed after crashing into a modified container truck at Cirebon, West Java. There were no fatalities, but the locomotive driver and a number of passengers were injured. The incident caused interruption of timetables, and the evacuation ran with difficulties because of the heavy weight of the CC206.
