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 linefor hauling freight and passenger train, and along South-Sumatera and Lampung Line for hauling freights. They have two drivers cabins, and the the most active double-cabin locomotives in Indonesia.

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for express passenger train duty, they are now mostly operated as switchers and haulers of local trains, or have been withdrawn.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). 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. But, due to the latest rule from Indonesia Goverment's Ministry of Transportation, every new locomotive should have no 'long-hood' position, to decreased numbers 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. the first-39-locos arrived in August 14, 2015., 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 a 'heavy-haul coal train' in south sumatera.
