Which component collects 600V DC power?

• A. Pantograph
• B. Third rail shoe
• C. Transformer
• D. Rectifier

Answer: (B)

In a 600V DC system, power is carried by a fixed rail along the track. The train uses a third rail shoe to press against and slide along this energized rail, drawing the current needed for the traction motors and systems. The pantograph is used on overhead-wire systems, not a rail, so it isn’t the collector here. A transformer changes levels or provides isolation, and a rectifier converts AC to DC when needed, but neither is the device that collects the power from the rail. So the component that collects the 600V DC power is the third rail shoe.
