What is one characteristic of the Special Proceed Authority system?

The Special Proceed Authority system is designed to manage train movements in certain scenarios where normal safety protocols might be adjusted due to specific operational requirements. One key characteristic of this system is that it permits entry into a section of track that may be occupied, ensuring that train crews operate with caution and are aware of the potential risks involved. This measure is particularly important in situations like maintenance work or track blockages, where a train might need to proceed despite the possibility of having another train already on the track.

By allowing controlled movement into potentially occupied sections, the system enables flexibility in railway operations while still prioritizing safety. It is crucial for train operators to receive precise instructions and maintain communication with the signal and safety systems to navigate these situations appropriately.
