KA Commuter line Jatinegara–Bogor or the Jakarta loop line was a commuter rail line in Indonesia, operated by PT Kereta Commuter Indonesia (KCI). The line connected Jatinegara station in East Jakarta and Bogor station in Bogor, West Java. On maps and diagrams, the line was shown using the colour "yellow" ( ). The Jatinegara–Bogor line was the second busiest line in the KA Commuter system.[1] Covering the distance of 69.35 kilometres, it was the longest KA Commuter line, combining the loop-line on Jatinegara–Kampung Bandan–Tanah Abang–Manggarai with Manggarai–Depok–Bogor lines.
The yellow line, especially the loopline corridor between Jatinegara and Manggarai stations was the main trunk line or feeder for KA Commuter line system. It connects to pink line at Kampung Bandan, brown line at Duri, green line at Tanah Abang, and blue line at Jatinegara and Manggarai. The line and stations between Manggarai and Bogor were shared with the red line. There was a branch line connecting Duri in West Jakarta to Nambo station in Bogor Regency, the intersection is located after Citayam.[2]
KAI Commuter announced in 21 May 2022 that the line would be deactivated by 28 May 2022, as part of Manggarai station upgrade. Its inner city loop section would be absorbed by a new alignment of Cikarang Line, to be known as Cikarang Loop Line, which operate in a full loop in addition to existing Jatinegara-Cikarang section. Its branch to Nambo would be redirected to Jakarta Kota instead of Angke as part of Bogor Line (currently known as Central Line) .[3]
