Which term denotes a territory where cab signals are used to convey information to the operator?

• A. ABS
• B. Line-Of-Sight
• C. Right-Of-Way
• D. Cab Signal Territory

Answer: (D)

Understanding terminology for areas served by cab signaling. Cab signal territory is the designation for a section of track where signal information is conveyed to the operator inside the locomotive cab. That makes it the best answer because it directly identifies the region where cab signals provide the information the engineer uses.

Other terms refer to different concepts: Automatic Block Signaling describes a wayside-based system of blocks and signals rather than cab-provided information; Line-of-Sight relates to signals read visually by the driver rather than cab displays; Right-Of-Way is about legal authority to use a track, not a signaling method or designated territory.
