What should be done before the scheduled departure time concerning the engineer's readiness?

Before the scheduled departure time, it is crucial for the engineer to be in the cab. This action signifies the engineer's readiness to assume control of the train and ensures that they are present to monitor any final preparations or communications from the train crew or dispatch. Being in the cab allows the engineer to familiarize themselves with the operational environment, review controls, and be prepared for any immediate operational needs or last-minute changes.

While conducting a safety briefing, completing a checklist, and initiating the systems check are all important tasks that contribute to the overall safety and efficiency of train operations, being in the cab is essential for confirming the engineer's physical presence and mental readiness at the time of departure. Physically being in the cab is often seen as the final step before actually departing, as it allows for immediate engagement with the train's operation and adherence to departure protocols.
