KA Commuter Line Merak

The Commuter Line Merak, historically operated as Local Merak, is a vital regional passenger rail service managed by KAI Commuter, a subsidiary of Indonesia’s national railway company, Kereta Api Indonesia. The service name derives from its primary western terminus at Merak Port, strategically linking the maritime gateway of Banten Province with the interior hub of Rangkasbitung. Serving as an indispensable socio-economic corridor, the line bridges coastal maritime transport with the Greater Jakarta rail network, facilitating daily commerce, labor mobility, and regional integration across western Java.

As a primary artery for passenger mobility, the service acts as an economic lifeline for rural communities, traders, and commuters traveling between coastal Banten and inland industrial centers. Despite operating in a challenging coastal environment, the service maintains high operational reliability through dedicated locomotive-hauled rolling stock designed to withstand regional climates. By connecting isolated rural stops directly to major transit hubs, the route significantly enhances regional connectivity, bridging the infrastructural gap between remote coastal districts and rapidly developing urban centers.

Under the current national rail graph schedule (Gapeka 2025), the service operates 14 scheduled daily trips across a route distance of approximately 69 kilometers. The journey traverses 11 scheduled stations with an average transit time of 1 hour and 48 minutes per end-to-end trip. To cater to the diverse socioeconomic needs of its passenger base, the service provides targeted seating configurations, specifically utilizing Economy Petani & Pedagang (Farmer and Trader) cars alongside standard Economy Public Service Obligation (PSO) carriages, ensuring affordable and accessible transport for all segments of the regional population.
