What is the device of "Necessary Track" used to change from one track to another?

• A. Lever
• B. Damper
• C. Gudgeon
• D. Switch

Answer: (D)

The device that changes a train from one track to another is the switch (also called points). The switch is the set of moveable rails at a junction that can be aligned to the straight track or the diverging track so the wheels follow the desired route. In practice, the switch is operated by a lever or motor to move the rails, but the essential component that actually redirects the train is the switch itself. A damper doesn’t direct routing, and a gudgeon is just a pivot pin used in other train components, not for switching tracks.
