Which term best describes a section of track whose use is controlled by signals?

• A. Auxiliary Track
• B. Bulletin
• C. Block
• D. Bumping Post

Answer: (C)

In railroad signaling, the track is divided into blocks—sections whose use is controlled by signals to manage train movements safely. Each block is protected by signals so trains can only enter when the block is clear. When a train is in a block, the signal for the next block will restrict entry until the block is vacated, preventing two trains from occupying or conflicting within the same section. This block-based system is what keeps trains spaced and moving in a controlled, predictable way. Auxiliary track refers to a siding or extra track used for storage or maneuvering, not the main signal-controlled section. A bulletin is a notice about conditions or rules for crews, not a track section. A bumping post is a safety device at the end of a track used to stop equipment, not a signal-controlled segment of track.
