Which tracks are main tracks and not part of the station track roster?

• A. 0 and 9
• B. 11 and 12
• C. 1 and 8
• D. 2 and 7

Answer: (A)

Main tracks are the through lines that trains use to pass the area without stopping at the station’s platform tracks. The station track roster, on the other hand, lists only the tracks that serve the station’s platforms and nearby facilities. Tracks that serve as through or bypass lines aren’t included in that roster because they aren’t used for platform access. In this layout, tracks numbered 0 and 9 function as those through/mainline tracks, so they aren’t part of the station’s track roster. That’s why they’re identified as the main tracks that are not part of the station’s roster.
