What must be done after a hand-operated dual control switch returns to power operation?

After a hand-operated dual control switch returns to power operation, it is crucial to notify the control operator. This action is essential because it ensures that the control operator is aware of the status of the switch and can manage train movements accordingly. Communication with the control operator maintains the operational safety and efficiency of the rail system, allowing for proper coordination among various teams, especially when switches are involved that can affect train routes and movements.

Notifying the control operator also serves to confirm that all procedures have been followed correctly and that any necessary actions can be taken based on the updated status of the switch. Keeping all relevant parties informed is a critical aspect of railway operations to prevent any potential conflicts or accidents that can arise from miscommunication or lack of information about track conditions and switch operations.
