What is the recommended action when operating a train under low adhesion conditions?

When operating a train under low adhesion conditions, it is recommended to reduce the operating speed. This action is essential because low adhesion can significantly reduce the train's ability to maintain traction on the tracks. By lowering the speed, the engineer can enhance the train's control and minimize the risk of slipping, which can lead to loss of control and potential accidents.

In low adhesion scenarios, such as those caused by rain, ice, or the accumulation of leaves on the tracks, trains may struggle to start, stop, or maintain speed. Reducing speed allows for safer and more manageable operation, ensuring that the train can respond appropriately to any changes in adhesion conditions without compromising safety. By taking this cautious approach, the engineer can navigate the challenges posed by low adhesion while ensuring the safety of the passengers and the integrity of the train system.
