Reasons for Crowded Green Line Commuter Trains Despite Passenger Numbers Being Half of Red Line

The carriages of the Jabodetabek Electric Rail Train (KRL) on the Rangkasbitung-Tanah Abang route are often seen crowded with passengers, particularly during morning and evening rush hours. Nevertheless, the Rangkasbitung-Tanah Abang KRL route, and vice versa, is not the busiest in terms of passenger numbers. According to the latest March 2026 data from KAI Commuter, the passenger count on this route is only half that of the Jakarta Kota-Bogor route and vice versa. From 1 to 29 March 2026, the Bogor line (Red Line) still holds the top position with the highest number of passengers at 11.9 million. Next is the Cikarang Line with 6.69 million passengers over the same period, followed by the Rangkasbitung Line with 6.29 million passengers. This situation is caused by several factors, from the number of train carriages to the train interval (headway). Currently, the Green Line KRL is served by 10-car train sets, while the Bogor route KRL actively uses 12-car train sets. The fewer number of carriages makes the Green Line KRL appear more crowded during rush hours. “We are currently in the trial phase to ensure that supporting infrastructure can accommodate the operation of Commuterline with 12-car configurations on the Green Line,” said VP Corporate Secretary of KAI Commuter, Karina Amanda, as reported by Kompas.com on Monday (2/3/2026). Karina confirmed that the 12-car KRL trial is to accommodate the high passenger growth on the Green Line route. A 12-car KRL is projected to carry 20 percent more passengers compared to a 10-car set. “If based on the evaluation it is still not feasible, then of course KAI, together with the Directorate General of Railways (DJKA) of the Ministry of Transportation, will continue to strengthen the infrastructure,” she said.
