Masinis

Masinis is the Indonesian term for a locomotive engineer or train driver. The masinis operates the locomotive and is responsible for the safe and timely movement of trains on passenger and freight services. The role covers both diesel-electric and electric locomotives within national rail networks.

Masinis work in coordination with conductors and other railway staff to ensure smooth operations and passenger safety.

Training and certification: Masinis undergo comprehensive training provided by the railway operator and/or national regulator, combining classroom instruction, driver simulators, and on-the-job coaching. They must obtain a professional license or certification, pass medical examinations, and participate in periodic retraining to stay current with signaling systems, procedures, and safety requirements. Ongoing assessments help ensure adherence to safety standards and operational guidelines.

Working conditions and scope: Masinis may work irregular hours and long shifts, operating on urban commuter lines or long-distance routes across varied terrain and weather. The term reflects a long-standing railway tradition and remains the standard designation for the person responsible for steering the locomotive in Indonesian rail transport.
