No-one is on the right line as yet.
I have added two photos of the rail infrastructure to the original post.
Woodstock has seen a train more recently than this location.
Llangothlin probably saw its last train in the same decade.
Rosewood would have seen its last train about a decade earlier than this location.
Without doing a precise survey Woodstock, Boorowa, and Hazelgrove would be a toss up for the closest as the crow flies with Hazelgrove probably the closest.
I am assuming the gates were restored by the local property owner as they seem to form the entrance not only to the rail location but also the adjacent property.
