What does a yellow background speed limit sign indicate for freight trains?

• A. Proceed at maximum permissible speed
• B. Proceed at the higher speed indicated
• C. Proceed at the lower speed indicated
• D. Stop unless given clearance

Answer: (C)

A yellow background speed limit sign indicates that freight trains must proceed at a lower speed than indicated on the sign. This is a crucial safety measure that helps to ensure safe operation conditions, particularly in areas where the track may have specific restrictions or potential hazards. The lower speed allows for the train to maintain control and provide adequate response time should unexpected situations arise, such as track obstructions or other operational concerns. This type of signaling ensures that train operators are aware of and adhere to regulated speeds, which may be necessary to safely navigate track geometry, curves, or areas with reduced visibility. By following the instructions indicated by the yellow background speed limit sign, train crews contribute to both their safety and the safety of the rail network as a whole.
