What is the status of the 17 track in Harrison Yard?

The choice indicating that the 17 track does not exist is correct because it reflects the current operational status of the yard. In many rail facilities, tracks can be renumbered, repurposed, or even removed based on changes in infrastructure and operational needs.

If there were elements suggesting that the track is under construction or out of service, those options would indicate that it is a track that once existed or is in the process of being created. Similarly, stating that it is located near Junction 4 presupposes the existence of the track in question. Thus, the assertion that the 17 track does not exist highlights a definitive conclusion about its status that is coherent with the operational details of the yard's layout.
