What term defines a track segment connecting the yard or yard tracks with the mainline?

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

Answer: (A)

Yard lead is the track segment that connects the yard to the mainline, providing the route for movements between yard tracks and the mainline. This lead lets locomotives and cars move in and out of the yard, serving as the entry and exit path for yard operations. The other terms describe different things: yard limits are the boundary within which yard-specific rules apply; a diverging route is any track that leaves the mainline toward another line, not specifically the yard connection; the normal switch position is simply the default alignment of a turnout and not the connection itself.
