KA Gajayana Tambahan

Operated by Kereta Api Indonesia (KAI) as an intercity rail service (Kereta Antarkota), the Gajayana Tambahan represents an essential supplementary iteration of the flagship Gajayana train. The moniker "Tambahan" designates its operational status as an auxiliary service deployed to augment passenger capacity along one of the nation's most heavily demanded corridors. Connecting Malang in East Java with Gambir station in Central Jakarta, the service functions as a vital logistical bridge across the island of Java. It links the dense metropolitan center of the capital with major regional hubs, catering to high-volume passenger flows driven by tourism, education, and commerce.

Beyond its supplementary designation, the service plays a crucial role in regional mobility by absorbing excess travel demand during peak holiday seasons, weekends, and national celebrations. Utilizing dependable rolling stock, the service maintains high standards of operational reliability and mechanical safety, ensuring consistent transit across varied geographical terrains. By providing a direct, high-capacity link between Malang and Jakarta, the route mitigates highway congestion and fosters economic integration between East Java and the capital region, reinforcing the accessibility of secondary and tertiary markets along the corridor.

Under current operational parameters governed by Gapeka 2025, the service operates 2 scheduled trips and serves 22 scheduled stations along its primary path. The journey covers a total route distance of approximately 906 kilometers with an average transit time of 13 hours and 43 minutes. Designed to prioritize passenger comfort during long-distance travel, the train is configured with Executive Mild Steel class equipment, offering standardized seating and amenities suited for extended intercity voyages.
