When Pantograph(s) are damaged what must be done?

• A. Stop immediately, report to the Train Dispatcher/Power Director, and await instructions.
• B. Inspect and then proceed.
• C. Notify conductor only.
• D. Continue to run, if speed is under 90 mph.

Answer: (C)

Pantographs damaged create an immediate safety concern in the traction power system because they affect how the train collects electric power from the overhead wire. The safest first step is to alert the person in charge on the train—the conductor—so they can take control of the situation, protect passengers, and coordinate with the engineer and the power control center as needed. The conductor serves as the onboard supervisor who initiates the proper safety actions and communicates with dispatch and the Power Director as required. Notifying the conductor ensures the issue is escalated through the correct chain of command and that appropriate steps—such as stopping the train or securing power—are implemented under guidance. Trying to inspect or continue operating without clear authorization can worsen the fault or create additional hazards, so the immediate focus is to get the conductor informed and let them direct the next actions.
