Behind the Train Journey: KAI Manages Rp1.23 Trillion in Spare Parts Inventory

PT Kereta Api Indonesia (Persero) is managing a net inventory of spare parts and materials worth Rp1.23 trillion as of 30 June 2026 to support the maintenance of its rolling stock and infrastructure. The figure comprises Rp1.12 trillion in rolling stock spare parts and Rp224.73 billion in infrastructure spare parts, before deducting impairment allowances.

Vice President Corporate Communication KAI Anne Purba said that spare parts readiness is a crucial part of operations, as KAI manages 12,856 units of rolling stock as of June 2026, consisting of 551 locomotives, 1,064 electric multiple units (KRL), 2,238 passenger carriages, 8,907 freight wagons, and 96 diesel-electric rail cars (KRDE/I).

“Passengers see the train when it is on the platform, but behind a single journey there is a lengthy maintenance process. More than 12,000 units of rolling stock require material support, technical personnel, workshops, depots, and disciplined maintenance schedules,” Anne said.

Rolling stock spare parts are used for routine and periodic maintenance of locomotives, passenger carriages, generator cars, diesel cars, electric cars, and freight wagons, carried out at workshops and depots across various Operational Areas and Regional Divisions.

Meanwhile, infrastructure spare parts are used to support the maintenance of railway tracks, bridges, level crossings, signalling systems, electrical installations, and communication installations. Their value reached Rp224.73 billion as of June 2026.

KAI’s asset management direction is also increasingly emphasising a data-driven life-cycle approach so that maintenance and renewal decisions can be made according to the condition and risk level of each asset.

“Journey reliability begins long before the train departs. Material management and maintenance are daily tasks to ensure that rolling stock and infrastructure are ready for use,” Anne concluded.
