Before foul time becomes effective for an employee, what must they do?

The correct answer emphasizes the importance of clear and precise communication in the dispatching process, particularly when it comes to safety protocols such as foul time. For foul time to effectively start for an employee, they must copy and repeat the information back to the dispatcher. This step ensures that the employee fully understands the instructions and confirms that they have received the correct details. By repeating the information, the dispatcher can verify that there are no misunderstandings or miscommunications which is critical in the high-stakes environment of train dispatching.

Clear communication is essential because it helps prevent accidents and ensures everyone is on the same page regarding safety procedures. This protocol also establishes accountability, as both the dispatcher and the employee confirm that the instruction has been given and received correctly. The other options do not fully encompass the safety and communication protocols necessary in this context.
