Portal Stanchions are a type of which railway infrastructure component?

• A. Stanchions
• B. Signals
• C. Cable Trunking
• D. Conductor

Answer: (A)

Portal Stanchions are a type of stanchion—the structural frames that hold up the overhead electrical line. A stanchion is basically the support that keeps the conductor in the correct position and away from the track, with insulators and hardware mounted on it. The “portal” design refers to a frame spanning the track, forming a doorway-like support structure for the conductor across gaps or entry points. They aren’t signals, which control train movement, nor cable trunking, which houses cables, nor are they the conductor itself. The purpose of a portal stanchion is to provide the physical support for the overhead line, making it a clear example of a stanchion.
