KA Cilawalu Tanker

The Cilawalu Tanker is an established Indonesian freight train service dedicated to the bulk transportation of petroleum and liquid fuels, operated by Kereta Api Indonesia (KAI) in synergy with state energy enterprise Pertamina. Historically serving as a vital logistics backbone for the southern corridor of Java, the service underpins regional energy security by seamlessly connecting the primary fuel terminal at Rewulu in Yogyakarta with the major distribution hub in Cilacap, Central Java. This rail corridor holds profound economic significance, bypassing highway congestion to ensure a steady, uninterrupted flow of combustible resources essential for industrial and domestic consumption across the provinces.

As a cornerstone of modern supply chain efficiency, the service delivers exceptional operational reliability by mitigating the logistical risks and environmental liabilities associated with long-distance road tanker fleets. The deployment of dedicated rail tankers leverages the inherent advantages of intermodal transport, consolidating massive volumes of hazardous materials into a single, highly regulated transit system that significantly reduces carbon emissions per ton-kilometer. By integrating directly with regional terminal infrastructure, the Cilawalu Tanker optimizes terminal turnaround times and maintains a dependable inventory cadence for downstream distribution networks.

Operating under the national rail graph Gapeka 2025, the Cilawalu Tanker executes a structured operational schedule consisting of 2 scheduled trips daily across a route distance of approximately 159 kilometers. The service efficiently navigates a network comprising 6 scheduled stations along the Central Java corridor, achieving an average transit time of 4 hours and 25 minutes. These specific technical parameters reflect a highly optimized operational tempo, balancing stringent safety protocols for hazardous cargo with the agility required to maintain fluid movement through densely populated and topographically diverse rail corridors.
