What must a transmitting employee say to indicate communication is complete and a response is expected?

In communications, particularly within the context of BNSF Maintenance of Way Operating Rules, it's crucial for clarity and understanding between employees. The term "Over" is a standard closing signal used in radio communication that indicates the transmission is complete, and a response is expected. By saying "Over," the transmitting employee signals to the receiver that they have finished their message and are now awaiting a reply.

This practice helps eliminate any confusion about whether the transmission is still ongoing or if it is time for the listener to respond. Using "Over" establishes a clear protocol that ensures effective and efficient communication, which is essential for safety and coordination in the maintenance of way operations. Other terms like "End," "Done," and "Finished" are not standard phrases in radio communications and do not carry the same universal recognition, potentially leading to misunderstandings in critical situations.
