If the first train reported to have a Form D overtakes another train, what is the responsibility of the delivery Office?

When the first train that was issued a Form D overtakes another train, the responsibility of the delivery office is to inform the originating officer of this situation. This communication is vital because it ensures that the originating officer is aware of any changes or developments that may affect train movements, safety, and operational efficiency.

The proper communication allows for timely adjustments and coordination between trains, especially in the context of following rules and maintaining safety protocols within the rail network. Keeping the originating officer informed allows for better decision-making as it relates to train control, and it helps in managing the overall system effectively.

In contrast, the other responsibilities are not primary actions in this scenario. Reissuing the Form D to the overtaken train would typically not be necessary as they would still be operating under the authority of their existing Form D. Cancelling the original Form D is not warranted since the overtaken train remains under its original authority and does not change unless directed otherwise. Notifying everyone about the delay could be part of a broader communication strategy but is not as crucial as directly informing the originating officer about the overtaking situation.
