Which device is used to throw and lock a switch and indicate its position?

• A. Switch Stand
• B. Switch Point Signal
• C. Timetable
• D. Track Shunt

Answer: (A)

The switch stand is the device that directly operates a turnout: you move the lever to throw the switch rails to the chosen path and it locks in place to prevent accidental changes. It also provides a visible indicator showing which route the switch is set to (for example, straight or diverging), so the operator and crews can confirm the position before proceeding. The other items don’t perform both actions: a switch point signal only indicates position, not physically move or lock the switch; a timetable is just a schedule; a track shunt is used to detect train presence, not operate a turnout.
