What term means to turn on electrical power to the catenary, messenger wire, and supporting equipment, at which time all devices connected are energized and live?

• A. False Occupancy
• B. Electric Switch Lock
• C. Energize
• D. De-Energize

Answer: (C)

Turning on traction power means applying electrical power to the overhead catenary, messenger wire, and supporting equipment so everything connected becomes live. This term describes the moment the system is energized, providing voltage to the trains and related devices. De-energize is simply the opposite—removing that power to make the system not live. The other terms don’t fit: false occupancy is a signaling status issue, not about powering the system; an electric switch lock is a safety device used to lock switches, not to energize the lines. So the correct term for making the system live is energize.
