What indication will display on the CBTC-TOD for employee pick-up?

In the context of the PATH Train operations and the use of the CBTC-TOD (Communication-Based Train Control - Train Operator Display), the indication that is displayed for employee pick-up is specifically designed to inform the train personnel about this operational necessity.

The correct response highlights that there is a dedicated visual or signal that directly communicates the requirement for an employee to be picked up, which is a crucial part of train operations involving personnel movements. This indication serves as a direct alert to the train engineer or the operator about the status of trains in relation to employee logistics.

Other options such as train arrival, emergency alerts, or indication of revenue service focus on different operational aspects but do not specifically refer to employee pick-up. Each of these aspects plays an important role in train management; however, they do not pertain to the specific function of indicating a need for an employee to be picked up. Thus, the clear distinction of the correct choice reinforces the specialized language and indicators used within the CBTC-TOD system for effective communication among train personnel.
