Are tracks 11 and 12 main tracks?

Explanation:
Tracks that carry through traffic are called main tracks, but when a group of tracks is within an interlocking, every movement on them is controlled by signals and switches that are interlocked to prevent conflicts. If tracks 11 and 12 are described as completely interlocked, that means they fall under this protected interlocking area, and their movements are governed by the interlocking system. Because of that, they are interlocking tracks rather than main tracks. Yard tracks, on the other hand, are for storage and typically aren’t described as being under the same interlocking protection.
