A defined area with limits is called what?

• A. Absolute Block
• B. Emergency
• C. Block
• D. Consist

Answer: (C)

A block is a defined stretch of track with set boundaries used in signaling to control train movements. Each block has fixed limits, typically marked by signals and interlocking, so only one train can occupy that section at a time. This arrangement creates safe headways by preventing trains from entering a section when another is still in it, and it’s monitored by track circuits or other occupancy detectors. The term describes the general concept of a defined area with limits. A more specific system is the absolute block, which is a stricter form of block control, but the broad term for any defined track section is simply a block.
