What defines non-controlled tracks?

Non-controlled tracks are defined by the fact that movements are allowed without requiring authorization from the dispatcher. This means that train movements can take place on these tracks without needing the dispatcher’s prior approval or instruction, allowing for more flexibility in operations.

This designation typically applies to tracks that may be used less frequently or for specific types of rail services, where continuous oversight by a dispatcher is not necessary. Non-controlled tracks can be especially important in situations where timely movement is vital, such as in certain freight operations or in yard movements.

The other options involve forms of control and monitoring that do not align with the definition of non-controlled tracks. For instance, requiring verbal authorization from the dispatcher, monitoring by CCTV, and periodic safety checks all indicate levels of oversight and control that characterize managed or controlled environments rather than non-controlled ones.
