A Train Engineer is a professional responsible for operating and driving trains. They ensure the safe and efficient transport of passengers and cargo across various routes. Train engineers must be knowledgeable about train systems, signals, and safety protocols to navigate tracks and manage the train's speed and braking. To become a train engineer, individuals typically need a high school diploma and specialized training, often through an apprenticeship or a formal program. They must also obtain a license from the relevant regulatory authority, such as the Federal Railroad Administration in the United States, to operate trains legally.
