It would probably be a tragedy if these places were built up like Bathurst's newer neighborhoods which lack trees and charm of the older pockets. They are an eyesore from Mount Panorama.
Maybe these stations can be revived for local tourism in some way and become a destination in their own right. e.g. steam train weekends, or even stops/pick up points on XPT or XPL pax when required.
The stations are already there....
Firstly, the old station at Perthville is gone. Georges PLains station is still there and could be used if the need arose, I understand it has historical significance and has/had a local historical tourist scty like group that used the building. With the new loop being put in place certainly return trips from Bx would work, but part of the enjoyment for passengers would be the climb to Wimbledon, but with push pull operations these days they can reverse from there anyway, although they would be restricted in speed owing to the tender first running.
I agree with you re the treeless landscape in housing estates. Thing is what you see out around Mt Panorama and across to the eastern range is that is all farmland that produces a lot of Lucerne and hay, also probably some vegetable farms still operate there as well, something that is needed. I see no reason in this day and age for rural towns/cities to have those pocky little blocks of land when 800--1000sgm blocks should be the norm as it allows play room for the kids and owners can plant trees for shade and the environment.
Thing is in this modern age the main play and exercise most kids get these days is on their thumbs machines.
