Which yard has Track 6 in its third rail?

Which yard has Track 6 in its third rail?

• A. Receiving Yard
• B. Advance Yard
• C. Neither yard
• D. Both yards

Answer: (B)

Electric tracks are identified by the presence of a third rail that powers electric locomotives or yard equipment. Each yard can have a different electrification layout, so knowing which tracks are on the third rail tells you where electric traction can operate. In this case, Track 6 is energized by the third rail in the Advance Yard. That means you can move cars on Track 6 there using electric power. The Receiving Yard does not have Track 6 on the third rail, so that track isn’t electrified in that yard. Since only the Advance Yard has Track 6 powered, it’s the correct choice. The idea that both, or neither, would have Track 6 on the third rail doesn’t fit the given setup.
