Jakarta – Indonesians will soon commemorate
National Railway Day, observed every September 28. The historic commemoration marks the courage of Indonesian railway workers who took control of railway companies from the Japanese authorities on September 28, 1945.
On September 28, 2026, PT Kereta Api Indonesia (Persero), or
KAI, will celebrate its
81st anniversary.
The development of Indonesia’s railway industry is supported not only by reliable operators such as KAI, but also by the growing capabilities of domestic manufacturers. One of its main pillars is
PT Industri Kereta Api (Persero), or PT INKA, the state-owned rolling-stock manufacturer headquartered in Madiun, East Java.
Established in 1981, INKA has strengthened its position as
Southeast Asia’s first integrated railway manufacturing company. Its products are used not only on Indonesia’s railway network but have also entered international markets, including
Bangladesh, the Philippines, Malaysia, Thailand, Singapore, and Australia.
INKA has a broad manufacturing portfolio covering passenger coaches, electric multiple units (KRL), diesel multiple units (KRD), light rail transit (LRT) vehicles, locomotives, freight wagons, and various special-purpose railway vehicles.
Here Are 20 Major Railway Products Manufactured by PT INKA
