When preparing to depart from a switch location, it is crucial to confirm that the main track switches are restored to their normal position and securely locked. This ensures the safe routing of the train onto the correct main track, minimizing the risk of accidents or derailments that could occur if the switches remain in the wrong position. Properly locking the switches is essential as well, as it prevents any unintended movements that could disrupt train operations.

Other options, while potentially relevant in various contexts, do not address the critical safety aspect required before a train departs. The color of the paint on the switches, for instance, may indicate maintenance status but does not guarantee operational safety. Visual inspection of the switches may be part of routine checks, yet it is insufficient on its own if the switches are not locked in place. Finally, ensuring all crew members are present, while essential for operational integrity, does not directly relate to the functionality and safety of the switches themselves.
