Which of the following is NOT a focus of a conductor's role?

The role of a conductor primarily revolves around the safe operation of the train, ensuring passenger comfort and communication, and adhering to regulations. Setting train fares and pricing typically falls under the purview of revenue management and marketing departments rather than the responsibilities of a conductor. Conductors focus on on-board operations, such as monitoring safety systems like positive train control, communicating with passengers regarding schedules and delays, and ensuring safety protocols are followed, which includes evaluating the condition of the train and its immediate environment. Therefore, the correct response highlights that fare setting is outside the direct responsibilities of a conductor.
