Green Line KRL Commuters Complain of Overcrowding and Long Waits, KCI Responds
Jakarta, CNBC Indonesia - Regular users (train children/commuters) of the KRL Commuter Line on the Tanah Abang-Rangkasbitung route are increasingly complaining about the fullness of the KRL during busy hours on weekdays, and these complaints have flooded several social media platforms. Many Tanah Abang-Rangkasbitung KRL users are complaining about the difficulty of boarding the KRL when going to and from work.
PT KAI Commuter has responded regarding the increasing number of complaints from regular passengers on that route during peak working hours, namely in the morning and evening.
Corporate Secretary Vice President of KAI Commuter, Karina Amanda, said that the increasing density of the Tanah Abang-Rangkasbitung KRL during peak hours is due to a rise in the number of passengers, but not accompanied by an increase in the number of trains, although KAI Commuter has added two extra trips during peak hours.
“The number of passengers is increasing every year; in 2025, the number of passengers on the Tanah Abang-Rangkasbitung KRL route rose 11% to over 77 million people, from over 69 million in 2024. We have added 2 extra trips during peak hours, which previously were 204 trips in 2025, becoming 206 trips this year,” Karina told CNBC Indonesia on Friday (27/3/2026).
She added that for peak hours, the distance between KRLs or headway is still around 10-15 minutes, so congestion during peak hours still occurs.
“For the Tanah Abang-Rangkasbitung trip headway, it is generally 10-15 minutes, where the Tanah Abang-Serpong line headway reaches 10 minutes, while Serpong-Rangkasbitung can be 15 minutes during peak hours,” she added.
Karina explained that the reason the Tanah Abang-Rangkasbitung KRL headway is still around 10-15 minutes during peak hours is because the infrastructure is not yet adequate to shorten the headway.
“The headway cannot yet be shortened because the signalling infrastructure on that line still uses a closed automatic block system, so the trips between KRLs can only serve trips from one station to another,” she explained.
Another constraint, according to her, is that the electrical capacity on that route is also not yet capable of operating longer KRLs, such as KRL with a 12-car formation.
“The infrastructure capacity constraints, namely the overhead line electrical power (LAA) and platforms that cannot yet accommodate SF 12 KRL, are also contributing to the suboptimal operation of the KRL,” she said.
Nevertheless, they continue to maintain headways during peak hours at around 10-15 minutes. Other efforts include ongoing coordination with PT Kereta Api Indonesia (Persero) or KAI, the Ministry of Transportation (Kemenhub), and related parties so that the infrastructure on that route can be updated, allowing headways and KRL capacity to increase.
“Not long ago, KAI Commuter conducted a trial of KRL trips with SF12 on the Rangkasbitung line as a form of our commitment to increasing train capacity. In addition, by maintaining trip headways during peak hours, we continue to coordinate with the government and KAI for its development,” she concluded.
