What do distant signals govern in CSS territory?

Distant signals in Centralized Traffic Control (CSS) territory are primarily utilized to indicate the approach to home signals. These signals serve as an advanced warning to the train crew of the upcoming conditions ahead. When a distant signal displays a clear aspect, it reassures the crew that the home signal ahead is likely to be set to proceed, whereas a caution aspect indicates there may be a need to slow down or prepare to stop at the home signal.

This function is crucial in maintaining safe operations, as it allows train crews to adjust their speed and approach more safely. Understanding the role of distant signals enhances situational awareness and ensures compliance with signaling rules, ultimately promoting safety in railway operations.
