The GE CM20EMP (also known as CC206 in Indonesia) are diesel-electric locomotives owned and operated by Kereta Api Indonesia (Indonesian Railways Co.) and built by GE Transportation. The GE CM20EMPs are multipurpose locomotives, not only for hauling passenger trains (i.e. executive class, business class, or economy class), but also freight trains. [2] [ citation needed ]
The locomotives' operations started in 2013, and become Indonesian Railway's main workhorses for hauling trains. These locomotives are operates along the Java main line [3] for hauling freight and passenger train, and along South Sumatra and Lampung for hauling freight trains, mainly unit coal trains from Tanjung Enim to Kertapati. They are double-cabin, and the most active double-cabin locomotives in Indonesia.
Before there was the GE CM20EMPs, there were older double-cab locomotives used in Indonesia, such as the CC200s (Alco-GE UM 106T), the BB301s and BB304s (Krupp M1500BB), and the BB305s (built by CFD). [4] While they were once used for express passenger trains, they are now mostly operated as switchers, and a large majority have been withdrawn.
In the mid 2000s, the Indonesian State Railways Co. decided to modernize its existing mainline fleet, with locomotives such as the recently introduced CC204s (C20EMP locomotives). However, with the increasing cost of maintenance, caused by aging and inefficient locomotives, in 2010, the company decided to buy new diesel–electric locomotives to be added to its roster. [5] [6] Due to the latest law from Indonesia Government's Ministry of Transportation, every new locomotive should no longer have a 'long-hood' position, to decrease the number of accidents. [7] This is related to limited sight of the engineer when the locomotives run on long-hood position.
By September 2012 the company had signed a contract for 100 locomotives of the CM20EMP type and these were introduced in 2013. The locomotives were supplied without bogies ━ the bogies were assembled by Barata Indonesia. After arrival in Indonesia, the locomotives were moved to Yogyakarta Workshops to be trialed and tested.[ citation needed ]
Additional 50 locomotives were ordered in 2014, with the first 39 locomotivess arriving on 14th of August 2015, [3] and were directly brought to Yogyakarta Workshops. After undergoing testing, 28 locomotives were transferred to Kertapati, South Sumatra to haul unit coal trains in South Sumatra. [8]
The last 11 units arrived in Tanjung Priok on 14th of July 2016. [9] As was before, the locomotives were brought to Yogyakarta Workshops to be trialed and tested. After undergoing testing, these 11 units were transferred to Kertapati, South Sumatra to fulfill demands for locomotives to haul unit coal trains.
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.[ citation needed ]
The locomotives uses a newer 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 has a different horns from the previous GE locos in Indonesia. While its predecessors use Wabco AA2 with factory note tuned to D, G (play perfect 4th mid C), the CC206 locomotives use Nathan 3rd gen P2 (Bell No. 1&4) with factory note tuned to D, A (play perfect 5th mid C), (Unlike the other P2 using Bell No. 1&2 play minor 3rd).
One CC206 locomotive can haul up to 16 passenger cars or 30 freight cars.
Initially, all CC206 of 2013 batch (no. 13 01 – 13 100) and some units of 2015 batch (no. 15 01 – 15 11) were allocated to various motive power depots across Java, while the rest of 2015 batch (no. 15 12 – 15 39) and all of the 2016 batch (no. 16 01 – 16 11) were allocated to Kertapati depot in South Sumatra. [10] [11]
In February 2021, two 2015 batch units (CC206 15 09 and CC206 15 10) of the Sidotopo depot in East Java were transferred to the Kertapati depot. [12] Further two units of 2015 batch (CC206 15 08 and CC206 15 11) from Sidotopo's fleet were transferred to Kertapati in March 2024. [13]
