What describes the connecting of two or more LRVs?

• A. A device that locks wheels
• B. The overhead support system
• C. The connecting of two or more LRVs
• D. The crossing gate

Answer: (C)

This question is about coupling LRVs. Coupling is the act of linking two or more LRVs so they can operate as a single train. When cars are coupled, they connect physically and share braking, propulsion, and control signals, allowing one operator to move and manage the whole train, which increases capacity and efficiency. The other options relate to separate components: a wheel-locking device is not about linking cars, the overhead support system provides power to the vehicles, and a crossing gate is a safety device at street intersections. So the idea described by connecting two or more LRVs is coupling.
