What components are included in the Hillside yard third rail?

• A. Tracks 1-7, hillside west lead & east lead tracks and transfer tracks A, B, M, & H
• B. Tracks 1-7, hillside west lead only and transfer tracks A, B, M, & H
• C. Tracks 2-6, hillside east lead & transfer tracks C, D, E, & F
• D. Tracks 3-9, hillside west lead & east lead tracks and transfer tracks X, Y, Z, & W

Answer: (A)

The main idea here is understanding what parts make up the powered section serving Hillside yard. The third rail setup includes every yard track that can be energized plus the access points that bring power to those tracks and the transfer links that connect the yard to other parts of the system. Specifically, it includes tracks 1 through 7, both hillside leads (west lead and east lead), and the transfer tracks A, B, M, and H. This full combination ensures all yard tracks are powered and that locomotives or cars can move between the yard and other lines via the transfer tracks. Other options miss components or use different designations, such as omitting one of the hillside leads, restricting the track range (e.g., not including all of 1–7), or listing transfer tracks that aren’t part of Hillside yard’s third-rail arrangement.
