Which function is performed by the vigilance toggle?

The vigilance toggle serves a specific function in the operation of a remote control locomotive, primarily related to maintaining safe operational protocols. When activated properly, it ensures that the operator is actively engaged and aware of their surroundings. If the operator does not respond to the system's prompts or alerts, the vigilance toggle is crucial in stopping locomotive operations. While the selected answer indicates the release of brakes, the correct function encompasses more of a broader operational consideration.

Typically, activating the vigilance toggle will indeed allow the system to track and ensure that the operator is vigilant and ready to take over operations. Failing to respond could ultimately lead to stopping functions for safety. Therefore, understanding its role in the context of affirming operator engagement is essential within the remote control operation system.

Other options related to stopping the locomotive, activating alarms, or resetting systems highlight functions that may occur due to the failure of vigilance but are not the primary purpose of the toggle itself. Focusing on its design ensures safety through operator engagement rather than directly manipulating locomotive operations in a basic sense.
