For decades, the locomotive depot in Madiun, a quiet city in East Java, existed solely to overhaul aging steam engines for Indonesia's colonial-era railway.

On August 29 of that year, the old railway authority formally handed over the keys. Within months, the first Indonesian-made freight boxcars rolled off the line, and a country that had always imported its rolling stock began learning to manufacture its own.
