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

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

Answer: (A)

A yard lead is the track segment that connects the yard to the mainline, providing the access path for moves between yard tracks and the through line. It “leads” from the yard onto the mainline, and is typically controlled by signals and interlocking to ensure safe entry and exit. This distinguishes it from a diverging route, which is a mainline branch that leaves the main and goes to another line (not specifically the yard connection). A trailable switch describes a type of switch, not the connecting segment itself, and the normal switch position refers to the default alignment of a turnout rather than the name of the connecting track.
