Which of the following could constitute a 'special instruction' in a track warrant?

• A. All of the above: speed limits through switches, hold-at-point instructions, meeting points, crossing rules, or contact instructions for approaching signals
• B. Speed limits only
• C. Weather-related notes only
• D. None

Answer: (D)

Special instructions are the warrant-specific directives that change or add to the normal movement rules for a particular operation, and they apply only when conditions require an explicit modification to standard procedures. The items listed—speed limits through switches, hold-at-point instructions, meeting points, crossing rules, or contact instructions for approaching signals—are all typical, everyday operational controls that would normally be covered by the warrant’s standard rules or procedures. They aren’t unusual, warrant-specific deviations, so they aren’t considered separate special instructions. That’s why none of them qualifies as a special instruction, and the correct choice is that none apply. If there were a truly unusual, one-time condition affecting movement, that could be a special instruction, but not these standard controls.
