From which track is Hillside yard accessible when traveling?

• A. Traveling east on track 10
• B. Traveling west on track 9
• C. Traveling east on track 9
• D. Traveling west on track 10

Answer: (A)

Access to Hillside yard depends on how the yard throat is connected to the mainline and which direction lines up with that turnout. In this layout, the yard feeds directly from the eastbound approach on track 10. When you’re traveling east on track 10, you encounter the turnout that leads straight into the yard, and the signals/switches permit that entry. Approaches from the other directions don’t line up with that yard throat or would require backing through switches, so they aren’t the direct, permitted way to enter Hillside yard.
