When operating in foggy conditions, what does NORAC require from train crews?

In foggy conditions, NORAC emphasizes safety and caution for train crews, which is reflected in the requirement to reduce speed and maintain vigilance. This approach minimizes the risk of accidents caused by limited visibility, allowing train operators to react promptly to any potential hazards. Reducing speed provides greater control over the train's movement and facilitates stopping short of any obstacles that may be obscured by fog. Additionally, maintaining vigilance ensures that crew members are alert to the signals along the track and can respond appropriately to any changes in circumstances surrounding the operation.

In contrast, increasing speed is counterproductive in low-visibility conditions because it reduces the time available to react to unforeseen obstacles. Continuously using the horn may alert others to the train's presence, but it does not address the core issue of navigating safely through fog. Finally, merely utilizing headlights does not compensate for reduced visibility, making it crucial to combine the use of headlights with a cautious speed. This comprehensive approach to safety aligns with best practices in freight operations under challenging weather conditions.
