What action is NOT part of preparing a train for departure?

The correct answer is based on the tasks that are directly related to the operational readiness and safety of the train. Preparing a train for departure involves crucial safety checks and logistical planning. Conducting a brake test ensures that the train's stopping systems are operational; inspecting safety equipment confirms that all safety measures are in place for a safe journey. Reviewing the train's schedule is essential for ensuring timely operations and adherence to planned routes and stops.

Checking passenger tickets, while important for ticketing and fare enforcement, does not relate to the operational preparation of the train. It is a passenger management task typically handled by onboard staff or at ticketing locations rather than a prerequisite for train departure. Thus, this action stands apart from the core responsibilities of preparing a train for its journey.
