How is the action to be taken for Rule 231 signs defined in MATC mode?

The action to be taken for Rule 231 signs in MATC mode is defined by adherence to posted speed signs. This means that operators must observe and comply with the speed restrictions indicated by these signs at all times while operating the train. Rule 231 establishes guidelines for train movements, especially regarding the speed at which trains can safely operate under various conditions.

In the context of MATC (Multi-Asset Train Control) mode, ensuring that the train is operated within the limits specified by posted speed signs is crucial for maintaining safety, preventing derailments, and ensuring efficient scheduling. By adhering to these speed limits, train crews can enhance operational safety and reliability, aligning their actions with the intended safety protocols outlined in Rule 231.

This focus on speed adherence highlights the importance of signage in train operations, emphasizing the critical role that posted signs play in the safe management of railway systems.
