The comment in the plan regarding a potential extension to either Oran Park or Bringelly gives me renewed confidence that a route taking it through to just north-west of the Oran Park land release is still a possibility. A major bus-rail interchange there would see a shift away from buses to Campbelltown from Camden, and instead a more logical (and quicker) feed from Camden-Narellan-Currans Hill to Oran Park. Three stops to Glenfield as distinct from a slow bus to Campbelltown & then 4 stops to Glenfield... makes a heap of sense to me.
From there it makes sense for the line to arc around to the northwest towards Luddenham & a potential connection to the main west near Penrith... Camden to Penrith in, what, 20 minutes? OK it isn't going to happen in my lifetime (I'm 47) but it makes a heap of sense to me.
I know I'll be one less car on the road once Leppington opens...
