Which device is used to throw, lock, and indicate the position of a switch, consisting of a base, spindle, lever and connecting rod?

• A. Tail Track
• B. Switch Stand
• C. Switch Point Signal
• D. Traction Power System

Answer: (B)

The switch stand is the device used to throw, lock, and indicate the position of a railroad turnout. It sits on a base and includes a spindle, a lever, and a connecting rod that transfers the operator’s movement to the switch rails. When the lever is moved, the mechanism shifts the rails to the desired position (throwing the switch). The stand also has a locking feature to secure the rails in place and a visual indicator that shows whether the switch is set straight or diverted. This combination—control, locking, and position indication—defines the switch stand.

Tail Track is simply the secondary track behind a turnout and does not include the mechanism to operate or lock the switch. Switch Point Signal is a signaling device that tells trains the status of the turnout, not the mechanical means to move and lock the switch. Traction Power System provides electrical power for trains and equipment, not switch operation.
