What term describes turning off electrical power to the catenary, messenger wire, and supporting equipment?

• A. Energize
• B. False Occupancy
• C. Derail
• D. De-Energize

Answer: (D)

Shutting off electrical power to the overhead traction system is called de-energize. This action ensures there’s no current flowing in the catenary, messenger wire, or supporting equipment, which is essential for safe maintenance or inspections. Energize would be turning power on, which is the opposite of what’s needed here. False Occupancy and Derail are unrelated terms: false occupancy relates to signaling about track occupancy, and derail refers to a device or action that moves a train off the track. So the correct term for turning off the power is de-energize.
