Which term refers to a place at which a block-limit signal is displayed?

• A. Block Station
• B. Block-Limit Station
• C. Interlocking Station
• D. Passenger Station

Answer: (B)

Block-limit signals mark the boundary of a block of track, and the place where that signal is displayed is called the block-limit station. This term specifically identifies the location that defines the block’s limit, not a general station or a location tied to interlocking or passenger services. The other terms don’t refer to where the block boundary signal is shown: a block station is too generic for the boundary, an interlocking station relates to routes and switches, and a passenger station is simply a facility for riders.
