Train drivers, or locomotive pilots, are strictly prohibited from sleeping while on duty to ensure the safety of passengers and cargo. Modern trains are equipped with a Vigilance Control Device (VCD), which requires the driver to press a pedal or button at regular intervals (often every 60 seconds); if the driver fails to respond, the system initiates an emergency brake application. To manage fatigue, rail authorities enforce strict rest periods between shifts—typically a minimum of 12 to 14 hours. During long-haul journeys, "crew changes" occur at designated stations so that one set of drivers can disembark for a full rest in a "Running Room" or lobby while a fresh crew takes over. While some newer 2026 regulations allow for very short, scheduled "power naps" of 10–20 minutes during long stationary breaks in specific freight contexts, sleeping in the cab while the train is in motion remains a serious disciplinary offense.
