When there are visible defects or obstructions in the catenary that may damage Pantograph(s), what action is required?

• A. Keep Pantograph(s) up and proceed with reduced speed.
• B. Drop Pantograph(s) and report the defect to the Train Dispatcher/Power Director.
• C. Inspect the Pantograph from the cab and continue.
• D. Notify the conductor only.

Answer: (B)

When you see visible defects or obstructions in the catenary that could damage the pantograph, you must drop the pantograph and report the defect to the Train Dispatcher or Power Director. The overhead wire carries high voltage, and any defect or obstruction can cause arcing or further damage if the pantograph remains in contact. Lowering the pantograph removes contact, reducing the risk until qualified personnel can inspect and, if needed, isolate power for repairs. Simply continuing with the pantograph up at reduced speed doesn’t eliminate the hazard or prevent damage, and notifying only the conductor doesn’t address the required power-control actions.
