Train engineers must be knowledgeable about the train's systems and signals, as well as the rules and regulations of the railway. To become a train engineer, individuals typically need a high school diploma and must complete a training program. This training often includes both classroom instruction and hands-on experience. Engineers must also pass a certification exam to ensure they can operate trains safely and efficiently, contributing to the overall safety of the railway system.
