On the Mildura line
There was a post a week ago on this subreddit asking why they don't reopen passenger services to Mildura, with the consensus being there was not great enough population for it.
However, Queensland runs the Inlander to Mt Isa, a town significantly smaller than Mildura, with only one decent sized town on the way (Charters Towers).
So if Queensland can run the Inlander, why can't Victoria run a V/Line to Mildura?
