Which of the following lists all five items that a train dispatcher can verbally change on a track warrant for bulletins?

• A. Date
• B. Engine Identification
• C. Speed Limit
• D. Track Warrant Number

Answer: (C)

Speed limits are the element that a dispatcher typically changes verbally on a track warrant through bulletins because they reflect dynamic operating conditions and need to be updated quickly for safe movement. A bulletin can alert crews to a temporary or adjusted speed restriction so trains can slow down or proceed with caution in response to track work, weather, or other hazards.

Dates, engine identifications, and track warrant numbers are formal identifiers tied to the official record of the warrant. Changing them verbally would risk misidentifying the authorization or corrupting the documentation, so they are not typically altered by bulletins. The date marks when the warrant is issued, the engine identification specifies which locomotive is in service, and the warrant number is the unique reference for the document; these elements require proper formal amendments rather than quick verbal edits.
