Which type of switches require special recording methods in non-signaled territory?

In non-signaled territory, radio-controlled switches necessitate special recording methods due to their operational complexity and the safety implications of their use. These switches are controlled remotely, which means that manual oversight and physical alignment are not present as they would be with traditional switches. The automation and distance from the actual switch make it necessary to maintain precise records to ensure safe operation and effective communication among train crews and dispatchers.

Proper documentation of radio-controlled switch operations helps track usage, any malfunctions, and maintenance schedules, which is crucial for safety in areas that lack signals. This additional layer of recording is essential to mitigate any risks associated with the reliance on remote technologies, ensuring that all personnel are aware of the status and operation of these switches in real-time.

In contrast, manually operated and remote-controlled switches may follow standard operating procedures that do not necessitate as stringent recording methods, primarily because their operations are more straightforward and typically include direct human oversight.
