KAI Commuter Loop Line

KAI Commuter Loop Line (also known as Jatinegara–Bogor Line) 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. 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 the Tanjung Priok Line at Kampung Bandan, Tangerang Line at Duri, Rangkasbitung Line at Tanah Abang, and the then-named Cikarang Line at Jatinegara and Manggarai. The line and stations between Manggarai and Bogor were shared with the then-named Central Line. There was a branch line connecting Duri in West Jakarta to Nambo station in Bogor Regency, the intersection was located after Citayam.

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 was absorbed by a new alignment of the Cikarang Line, which was renamed Cikarang Loop Line, with trains running in a full loop in addition to existing Jatinegara-Cikarang section. Its branch to Nambo was absorbed by the Central Line, which was renamed Bogor Line, with trains running to and from Jakarta Kota instead of Angke.
