What is required for movement on a main track in Non-Signaled DCS territory?

Movement on a main track in Non-Signaled DCS (Direct Control System) territory necessitates obtaining Form D line 2 authorization. This is essential because in Non-Signaled areas, there are no fixed signals to convey movement authority, so alternative methods must be employed to ensure safe operations.

Form D line 2 provides the necessary authorization for a train to operate on a specific segment of track. It outlines the conditions under which the movement can occur, such as track occupancy and any specific instructions related to the movement. This process is a fundamental safety measure that allows trains to move in a controlled manner even in the absence of traditional signaling systems.

In this context, other options, while related to safety and operational protocols, do not adequately guarantee movement authority in Non-Signaled DCS territory. For example, verbal permission from the Dispatcher, although important for communication, does not constitute a formal authorization required for main track movement. Manual flagging procedures serve as a method of ensuring safety for specific situations but do not provide the necessary movement authority on their own. Lastly, automatic signaling by devices is not applicable since the territory in question is designated as Non-Signaled, where such devices do not provide signaling functions.
