Track warrants are used to control movement in which contexts?

• A. They are used for bulletins and for movement
• B. They are used only for movement
• C. They are used only for bulletins
• D. They replace signals at crossings

Answer: (A)

Track warrants provide authority for trains to occupy and move through a defined block of track, issued by the dispatcher to manage movement. They also handle bulletins, which are separate messages that convey temporary instructions or conditions—such as speed restrictions, track work ahead, or other notes the crew must follow while the warrant is in effect. Using warrants together with bulletins lets dispatchers control both where trains can go and under what updated conditions, ensuring safe operation. They don’t replace crossing signals, and they aren’t used only for movement or only for bulletins, so the combined use for both movement authority and bulletins is the best fit.
