Crew fatigue, particularly in the context of freight operations, is primarily defined as a condition that adversely affects both physical and mental capability. When crew members experience fatigue, their cognitive functions, decision-making skills, reaction times, and overall operational effectiveness are significantly impaired. This deterioration can lead to increased risks in safety and operational efficiency, which are critical in freight operations where attention to detail and responsiveness are vital for safe handling of trains and cargo.

Understanding crew fatigue is essential for creating effective work schedules and implementing rest periods that allow for recovery, thus mitigating the risks associated with fatigue. The other definitions offered do not capture the essence of fatigue; a normal state of alertness and readiness or a level of stress that enhances performance do not accurately reflect the risks and consequences associated with fatigue, while a period of rest is a mitigating factor rather than a definition of fatigue itself.
