What term designates a point designated by yard limits signs which separates the mainline from the yard when exiting at the CROF and NWROF facilities?

• A. Normal Switch Position
• B. Yard Limits
• C. Diverging Route
• D. Trailable Switch

Answer: (B)

Yard limits designate the boundary between the yard area and the mainline. The signs placed at this boundary mark where yard operations end and through mainline operations begin, which is exactly the point described when exiting at the CROF and NWROF facilities. This term specifically identifies the boundary you cross when moving from yard into the mainline, and signals, speed rules, and authority typically change at that point. The other terms refer to equipment or routes rather than the boundary itself, so they don’t describe this crossing point.
