What does a flashing yellow light indicate on a shunt ahead signal?

• A. Proceed at normal speed
• B. Change of direction required
• C. Restricted speed to the Shunt limit board
• D. Immediate stop is necessary

Answer: (C)

A flashing yellow light on a shunt ahead signal indicates that a train must proceed at a restricted speed to the Shunt limit board. This is critical for maintaining safety and ensuring the smooth operation of rail movements, especially in areas where there may be equipment, other trains, or personnel on or near the tracks. This signal serves as a warning to operators to prepare for potential conditions ahead that require cautious movement. By adhering to the instruction to proceed at restricted speed, train operators can successfully navigate the area while remaining alert to any changes or obstacles that might necessitate a halt or further caution. The specific mention of the Shunt limit board provides clear guidance on the expected action and helps maintain safety protocols in shunting operations.
