Which is a stanchion type?

• A. Portal: Frame you drive through
• B. Cantilever: Half Frame
• C. Stand Off: Mainly situated on curves
• D. Support: Holds the rails

Answer: (C)

Stand-off stanchions are designed to be placed mainly on curves. Stanchions are the posts that support the overhead line, and on curved sections the line needs extra offset from the track to maintain proper clearance and contact wire geometry as it follows the bend. The stand-off arrangement accomplishes this by projecting the support away from the track, keeping the wire at the correct height and distance. The other designs have different roles: a portal creates a frame spanning across the track, a cantilever uses an arm extending from one side, and a plain support that holds rails isn’t a stanchion type used for overhead lines.
