What must be done before foul time is granted in signaled territory?

Before foul time is granted in signaled territory, it is essential to ensure that STOP signals have been displayed. This action is crucial because displaying STOP signals effectively communicates to train crews that their movement must be halted, ensuring safety while work is conducted in the area. By having these signals in place, it prevents any potential collisions or accidents within the signaled territory when foul time is in effect.

In a safe operational environment, confirming that STOP signals are displayed takes precedence as it establishes a clear and unambiguous directive to all train crews, allowing them to understand that they must stop and are not to proceed until clearance is given. Thus, this step is fundamental to maintaining safety and orderly operations before foul time can be officially recognized and granted.
