What does 'limited visibility' refer to, and how should conductors react?

Limited visibility refers to situations where sightlines are obstructed, which could be due to various factors such as weather conditions, obstructions in the environment, or increased traffic around the train. In these scenarios, it is crucial for conductors to prioritize safety by reducing speed and increasing their alertness to effectively respond to any unforeseen situations or hazards that may arise.

By reducing speed, conductors can give themselves more time to react to obstacles or changes in the environment, while heightened alertness allows them to notice any potential dangers that might not be easily visible in limited visibility conditions. This proactive approach ensures the safety of both the train crew and passengers, as well as those in the surrounding areas.

Other choices do not encompass the broad definition of limited visibility scenarios, as they specify particular conditions or actions which do not align with the general definition and necessary conductor response in such situations.
