Trainmen are individuals who work on trains, specifically in the operation, maintenance, and safety of trains. However, there are other terms that can refer to trainmen in different contexts. For example, in the British railway system, trainmen are called "guards." In North America, conductors are often used interchangeably with trainmen. Other terms used to refer to trainmen include engineers, operators, and brakemen. These terms were typically used in early railway systems when trainmen had specific roles such as operating the train's engine or braking system. Though the term trainmen is still common, other synonyms reflect the changes in railway operations and roles.
