What does it mean when a train operator observes two short whistle signals from a conductor?

When a train operator observes two short whistle signals from a conductor, it indicates that the operator should prepare for departure. This signal is a standard communication method used in rail operations to convey readiness to leave the station. The two short whistle signals serve as a clear instruction that it is time to focus on departure procedures, ensuring that the operator confirms all is in order before proceeding.

Understanding this signal is crucial for maintaining safety and efficient operations, as it prompts the operator to verify the train’s readiness, check for passengers, and ensure compliance with all safety protocols before the journey continues. Familiarity with such signals enhances coordination between the conductor and the operator, which is essential in the railway environment.

The other options do not accurately represent the purpose of the two short whistle signals, as they refer to different actions or statuses related to train operations.
