What would be your speed past a signal that becomes visible after entering yard limits?

Answer: C — Restricted speed

When you pass a signal that becomes visible after entering yard limits, the appropriate speed is restricted speed. Restricted speed is designed to ensure safety in areas where there may be other train movements, work crews, or obstructions that could pose a risk. This speed allows for the ability to stop within half the sight distance of the track ahead and is critical for navigating through yard limits where conditions can change rapidly. In yard limits, train crews must remain vigilant and prepared for any sudden changes in the situation. By adhering to restricted speed, conductors can maintain a level of safety and control, ensuring they can react to any unforeseen circumstances such as other trains on the track, equipment maintenance, or personnel on or near the tracks. This practice is essential within yard limits to protect both the crew and any operations taking place in the area.
