GE CM20EMP

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 which have general purpose, not only for hauling passenger trains (i.e. executive class, business class, or economy class), 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^[1] for hauling freight and passenger train, and along South-Sumatera and Lampung Line for hauling freights. They have two drivers cabins, and the most active double-cabin locomotives in Indonesia.

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).^[2] 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for express passenger train duty, they are now mostly operated as switchers and haulers of local trains, or have been withdrawn.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). But, with the increasing cost of mainternance, parts, fuel and workers, causing by aging and in-efficient locomotives, in 2010, the company decided to buy new diesel-electric locomotives to be added to its rolling stock and replace some aging locomotives.^[3] But, due to the latest rule from Indonesia Government's Ministry of Transportation, every new locomotive should have no 'long-hood' position, to decreased numbers of accidents.^[4] 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. the first-39-locos arrived in August 14, 2015.,^[5][6] and directly be brought to Pengok, Yogyakarta. After test, 28 locomotives numbered from CC 206 112 (CC 206 15 12) till CC 206 139 (CC 206 15 39) were transfered to Kertapati, South Sumatera by Panjang port, to haul coal trains in south sumatera.^[7]

The last-11-locos arrived in Tanjung Priok Port on July 14, 2016.^[8] 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 sumatera 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 (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,^[9] the CC206 locomotives use Nathan P3.^[10]

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 (dipo induk in bahasa) except Madiun and Jember.. CC 206 numbered from 101 (CC 206 15 01) till 11 (CC 206 15 11) are operated in Java, While the rest of CC 206 which arrived in 2015 ( from CC206 15 12 till CC 206 15 39) and which were arrived in 2016 (from CC 206 16 01 till CC 206 16 11) are now operated in South Sumatera, and allocated to motive power depot (dipo induk) 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 (CC206 13 16) was heavily damaged on its A-side.^[11] All the victims were injured on their feet and faces.^[12]
• 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.^[13]
• On 4 May 2014, the locomotive numbered CC206 13 69 and a power car (P 0 08 01) 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.^[14]
