What action is recommended when operating in low adhesion conditions?

When operating in low adhesion conditions, the recommended action is to reduce operating speed and brake earlier. This approach is essential for maintaining safety and control of the train under such challenging conditions, where traction may be compromised due to factors like rain, snow, or ice on the tracks.

Reducing speed allows for better handling of the train, helping the engineer maintain greater awareness of the conditions and enabling a more gradual application of brakes. This is particularly important because lower adhesion means that the train requires a longer distance to stop. By braking earlier, the engineer can ensure that the train comes to a stop safely within the available distance, while also minimizing the risk of skidding or sliding.

Maintaining a higher speed in low adhesion conditions can lead to a loss of control and an increased risk of accidents or derailments. Furthermore, ignoring adhesion conditions or proceeding normally can exacerbate the situation, making it difficult to stop, change direction, or respond to unexpected obstacles. Using emergency brakes immediately is also not advisable unless absolutely necessary, as it can lead to excessive wear and potentially destabilize the train if it is moving too fast. Therefore, the recommended practice focuses on proactive measures to ensure safe and effective operation in low adhesion conditions.
