Tail Track is best described as:

Tail Track is best described as:

• A. A signal that indicates switch alignment.
• B. A Mainline track designated for train storage outside of signal territory, usually located at a terminal.
• C. A track used for parking maintenance vehicles.
• D. A segment of track used exclusively for freight.

Answer: (B)

Tail track is a mainline-style track set aside for storing a train when it’s not in service, and it’s located outside of the signal territory, usually at a terminal. This setup gives you a dedicated place to park or stage a train without tying up the active mainline or interlocking signals, which helps keep mainline traffic flowing smoothly. It’s not specifically for signaling switch alignment, not limited to parking maintenance vehicles, and not restricted to freight—its purpose is general storage or staging at a terminal.
