What is a pantograph in a light rail system?

• A. A device affixed to the top of an LRV used to conduct electric power from the overhead contact wire.
• B. A ramp on each end of the platform used for boarding and alighting passengers with mobility impairments.
• C. An unforeseen event or occurrence which results in injury or property damage.
• D. Information communicated by radio to all trains which must be acknowledged back to Control by all Train Operators in train number sequence and recorded on their clearance.

Answer: (A)

A pantograph is a device mounted on the roof of an electric light rail vehicle that slides along the overhead contact wire to collect electrical power for the train’s traction motors. It stays in constant contact with the live wire, allowing current to flow into the train while the vehicle moves, with the return path completed through the rails. This setup is used in systems where power is supplied from an overhead line. The other options describe features or events unrelated to how the vehicle receives electricity.
