What is the primary function of the Low Adhesion feature?

The primary function of the Low Adhesion feature is to prevent station overruns and operational difficulties. This feature is crucial during adverse weather conditions, such as rain, snow, or ice, where the train's wheels may have reduced traction on the tracks. By recognizing low adhesion scenarios, the system can adjust the train's braking and acceleration behaviors, ensuring that trains maintain control and adhere to safety protocols. This proactive measure significantly enhances operational safety by preventing potential accidents or unwanted stopovers and ensuring trains can operate within safe limits, especially when approaching stations.

Contextually, the other options do not align with the primary purpose of the Low Adhesion feature. For instance, it does not increase train speed under adverse conditions, as safety and control take precedence. Similarly, while it can lead to reduced maintenance checks by promoting safety in operations, that is not its primary purpose. The feature does not enable automated braking in all conditions; rather, it specifically assists in instances where low adhesion is detected, ensuring that the trains do not exceed safe operational standards.
