What does 'restrictive speed' imply in rail operations?

• A. A maximum speed regardless of conditions.
• B. A speed limit only at night.
• C. A reduced speed under certain conditions to allow safe stopping within a limited distance.
• D. Free-flow speed in all track segments.

Answer: (C)

Restrictive speed means you operate at a reduced speed because conditions require you to be able to stop within the distance you can observe or within the limits of the track block. This level of speed is chosen to ensure you can stop in time for signals, potential hazards, or changes in track conditions ahead. It’s about being prepared to stop quickly when visibility is limited or when conditions could require an abrupt stop, not about a universal maximum or a time-of-day rule. So you slow down to safely manage stopping distance under those specific circumstances; it’s not free-flow speed or only a night-based limit.
