When operating or verifying the position of a hand-operated switch or fixed derail, employees must?

• A. Visually determine that switch points fit properly and the target corresponds with the positions.
• B. Check that the electrical circuit is energized.
• C. Listen for audible indication.
• D. Only verify after movement is complete.

Answer: (A)

The key idea is to make a positive, direct confirmation of the switch’s setting. When operating or verifying a hand-operated switch or fixed derail, you must visually confirm that the switch points fit properly and that the indicator target shows the correct position for the intended route. This direct sight check is essential because mechanical issues, wear, or obstructions can leave the device in the wrong position even if other cues seem fine. Relying on sounds or electrical status alone isn’t reliable, and waiting to verify only after movement can miss a misalignment that could cause a derailment. By performing a clear visual check, you ensure the track is actually set correctly before trains proceed and after movement as a safeguard.
