KAI Commuter Cikarang Loop Line

The Cikarang Loop Line (formerly Bekasi Line and Cikarang Line), officially the Cikarang Commuter Line, is a commuter rail line in Jakarta, Indonesia which is operated by PT Kereta Commuter Indonesia (KCI). The line connects Kampung Bandan station in North Jakarta and Cikarang station in Cikarang, Bekasi Regency, West Java. On maps and diagrams, the line is shown using the color "blue". Jakarta Kota–Cikarang is the extension of previously Jakarta Kota–Bekasi line which connects to Cikarang since 8 October 2017.

As of 2015, the line is the third-busiest line in the KA Commuter system, after red line and yellow line.

Before 28 May 2022, there used to be two routes operating between Jakarta Kota and Bekasi. One serves via Manggarai and other one via Pasar Senen. Line and stations between Jakarta Kota and Manggarai were shared with the Jakarta Kota–Bogor line.

KAI Commuter announced in 21 May 2022 that the line will be renamed as Cikarang Loop Line with new abbreviation (C) by 28 May 2022, as part of Manggarai station upgrade. The line ceased operating to Jakarta Kota and no longer serves Jakarta Kota–Manggarai segment, which is served exclusively by the Bogor Line. Trains from Bekasi or Cikarang arriving at Jatinegara now continue through city loop previously used by Loop Line, clockwise or counterclockwise, and then return to Bekasi or Cikarang. Several trains end their journey at Angke or Kampung Bandan without looping. In response to passenger congestion at Manggarai, a feeder service serving Manggarai–Angke/Kampung Bandan portion of the line was introduced on 30 May 2022 to minimise waiting time.

Main line
There are eight main service patterns of the line.

Jakarta Kota branch line
In addition, there are two minority services serving Jakarta Kota that only operates at certain times outside of rush hour (such as midnight and early hours) and is not officially acknowledged on the map. Note: Pasar Senen is one-way only for counterclockwise trains heading towards Kampung Bandan or Jakarta Kota. Train heading towards Bekasi or Cikarang does not stop at this station regardless of which service pattern it belongs to.
