Final answer:
A conductor or engineer needs to obtain permission, familiarize themselves with the new subdivision, and may require additional training before operating on a subdivision not listed on their dispatcher bulletin.
Step-by-step explanation:
Before operating on a subdivision not listed on their dispatcher bulletin, a conductor or engineer needs to go through a few requirements to ensure safety and efficiency.
Firstly, they should obtain permission from their supervisor or dispatcher to operate on the new subdivision. This is necessary to ensure that they have the authority and resources to perform their duties in the new area.
Secondly, they should familiarize themselves with the specific characteristics of the new subdivision, such as the layout of the tracks, signals, and speed restrictions. This will help them navigate the territory safely and efficiently.
Lastly, they may be required to undergo additional training or certification to operate on the new subdivision, especially if it has unique features or operational requirements.
