What is the speed that permits stopping at half the range of vision and looking for BROKEN RAIL?

• A. Normal speed
• B. Restricted Speed
• C. Clear Proceed
• D. Medium speed

Answer: (B)

The concept being tested is the need to protect stopping distance when visibility is limited by track conditions or hazards. Restricted speed is defined as the speed at which a train may proceed so that it can stop within the range of vision, and in some formulations, within half that range, to enable a prompt stop for an observed hazard such as a broken rail. So, when you’re looking for a broken rail or other danger and only part of the track ahead is visible, you must slow to restricted speed. This ensures you can bring the train to a stop within the distance you can see, giving you time to inspect the track and respond safely. Normal speed would not provide that guaranteed stopping distance, and other terms like clear proceed or other nonstandard speeds don’t reflect this safety requirement.
