When can a Dispatcher give a "Time Effective" on a Form D?

A Dispatcher can give a "Time Effective" on a Form D once the Form D has been repeated correctly by the relevant personnel. This step is crucial as it confirms that the information has been accurately communicated and understood, ensuring that all parties involved are aware of the specific instructions and requirements associated with the Form D.

The process of requiring a confirmation reinforces safety and operational integrity in train movements. A "Time Effective" status indicates that the instructions are not only acknowledged but are now in effect, allowing for the appropriate actions to be taken according to the directives outlined in the Form D.

Other options do not align with the necessary protocol for establishing a "Time Effective" status, as they either imply an action before confirming understanding or do not follow the correct procedural sequence. This emphasis on clear communication and verification is essential within dispatcher operations to maintain safety and efficiency in train handling.
