Movable Point Frog refers to:

Movable Point Frog refers to:

• A. A fixed frog used on all main tracks.
• B. A frog that cannot move due to maintenance.
• C. Movable Point Frog
• D. A signaling device showing turnout status.

Answer: (C)

A movable point frog is a turnout crossing where the rails that form the points can move to align with either the straight main track or the diverging route. When the turnout is set for a chosen path, the point rails shift so the wheels can ride smoothly from the entering track onto the selected route. This moving-rail design improves alignment and reduces wheel impact compared to a fixed crossing. It’s not a fixed frog, nor a maintenance-disabled frog, nor a signaling device—it's the control of the crossing rails themselves that defines the movable point frog.
