Who issues a new or extended warrant when the current warrant expires or continued movement is required?

• A. The Dispatcher issues.
• B. The Train Crew issues.
• C. The Interlocking Operator issues.
• D. The Station Master issues.

Answer: (D)

The person who issues a new or extended track warrant is the Dispatcher. In Track Warrant Control, movement authority is granted by the Dispatcher to the Train Crew, and when the current warrant is about to expire or the train needs to keep moving, the Dispatcher issues a fresh warrant or extends the existing one so the train can continue legally and safely. The Train Crew can request a renewal, but they don’t issue warrants themselves. The Interlocking Operator manages signals and switches, and the Station Master handles station operations, but neither typically issues mainline warrants. The new warrant replaces the old authority and covers the next segment or period of movement as directed by the Dispatcher.
