Construction of Karet–Sudirman Integration Underway, Travelator Assembly Begins at Sudirman Baru
The integration work between Karet Station and Sudirman Baru Station is progressing. As of October 2026, construction work is underway in the Karet Station area, while the travelator equipment has arrived at Sudirman Baru Station and is currently being assembled.
The development of these facilities is part of the arrangement of access between the Karet and Sudirman Baru areas following the relocation of Commuter Line Jabodetabek passenger boarding and alighting services from Karet Station to Sudirman Baru Station starting September 1, 2026. The integration work is scheduled to continue through December 31, 2026.
Vice President of Corporate Communication KAI Anne Purba said that the work is being carried out while taking into account customer journeys and community activities in the surrounding area.
“Construction work in the Karet area is continuing. At the same time, the travelator equipment has arrived at Sudirman Baru and entered the assembly stage. KAI continues to oversee every stage of the work to ensure that this connecting facility can support customer access between the Karet and Sudirman Baru areas,” said Anne.
As part of the development, KAI is preparing one 20-meter-long horizontal travelator and two vertical travelators. The improvements also include pedestrian corridors, station landscaping, drop-off areas for onward transportation, and other supporting facilities in the Karet area. On the Kendal side, the work includes the addition of access escalators, a canopy along the walkway, and improvements to the pedestrian corridor.
Daily Activity at Sudirman Baru Increases from 6,100 to 21,500
Following the service relocation on September 1, changes in customer travel patterns have begun to emerge at Sudirman Baru.
In August 2026, before the service relocation, Commuter Line Jabodetabek activity at Sudirman Baru Station totaled 190,060, or an average of 6,131 activities per day.
In September 2026, after passenger boarding and alighting services from Karet were relocated to Sudirman Baru, the activity increased to 646,411, or an average of 21,547 activities per day.
This means that the average daily Commuter Line Jabodetabek activity at Sudirman Baru increased by approximately 251.45% in one month.
In detail, average gate-in activity increased from around 3,691 customers per day in August to 11,804 customers per day in September. Meanwhile, average gate-out activity increased from around 2,440 to 9,743 customers per day.
On weekdays, the change was also significant. Average activity at Sudirman Baru increased from around 7,862 activities per day in August to 26,178 activities per day in September, an increase of approximately 233%.
“Before the relocation, average activity at Sudirman Baru was around 6,100 per day. In September, the figure had exceeded 21,500 per day. On weekdays, the average even reached more than 26,000 activities. This data shows that customers have begun adjusting their travel patterns since services were centralized at Sudirman Baru,” said Anne.
For comparison, Karet Station recorded 606,724 customer activities in August 2026, or an average of around 19,572 activities per day, before passenger boarding and alighting services were relocated at the beginning of September.
Activity at Nearby Stations Also Increases
Changes in passenger volume were also seen at Sudirman Station, which is located in the surrounding area.
Activity at Sudirman Station increased from 2,304,280 in August to 2,474,878 in September 2026.
On a daily basis, the average increased from around 74,332 to 82,496 activities, or approximately 10.98%.
On weekdays, the average activity at Sudirman Station also increased from around 82,881 to 91,745 activities per day.
The data shows that the growth at Sudirman Baru occurred alongside high travel activity in the Sudirman area, although the increase at Sudirman Baru was significantly greater following the relocation of services from Karet.
Commuter Line Airport Activity at Sudirman Baru Remains Relatively Stable
Sudirman Baru also serves Commuter Line Airport customers. Activity for this service is recorded separately from Commuter Line Jabodetabek.
In August 2026, Commuter Line Airport activity at Sudirman Baru totaled 78,587, or an average of around 2,535 activities per day.
In September 2026, the volume reached 75,654, or an average of around 2,522 activities per day.
Therefore, average daily Commuter Line Airport activity at Sudirman Baru remained relatively stable, declining by around 0.52% compared with August.
This means that the significant increase in activity at Sudirman Baru in September was primarily driven by Commuter Line Jabodetabek services, in line with the relocation of passenger services from Karet starting September 1.
“Customer data is one of our references in assessing developments in this area. The largest increase occurred in Commuter Line Jabodetabek activity, while Commuter Line Airport services remained relatively stable. Therefore, the facility improvements are being developed in line with the travel needs currently seen in the field,” said Anne.
Before the service relocation, from January to August 2026, Karet Station and Sudirman Baru Station together recorded 6,702,680 customer activities, consisting of 4,909,334 activities at Karet and 1,793,346 activities at Sudirman Baru.
KAI aims for the Karet–Sudirman Baru integration work to support easier customer movement through a more accessible connecting route, while also improving pedestrian and onward transportation access in the area.
“We want this work to provide easy-to-use access for daily activities. Construction and travelator assembly are continuing, while we continue to evaluate customer travel patterns throughout the integration period,” Anne concluded.
