This would seem to be a request for no reason. There is rail at 4 towns nearby that can be used including tocumwal. What is there to achieve by reopening this rail line?
Well, you gotta look at the incentives.
NSW Govt doesnt want to do it because of a) funding and b) the vacuum effect of improved infrastructure redirecting freight volumes to Melbourne where those pesky victorians can benefit from it at the expense of the good people of NSW.
So they do a report to win a by-election but then hide it by having an information session in Wagga (2hrs drive from the area) announced 2 days before the session, and put out a pretty flimsy executive summary that is pretty poor in quality and uses pictures of the worst part of the track to say 'look how bad it is'.
Yes there are some volumes that are probably confidential, however some of the volumes in it are probably wrong too. They used the 2016 Strategic Freight Model as the basis which is known to be woefully innacccurate in a range of ways.
At the same time, the NSW Govt has looked at building a line from Wumbulgul across country to somewhere near Barellan to try and divert the MC/CM trains from Riverina to Melbourne to Sydney instead....
Edit 2: Victoria is too focussed on passegner services and has shot itself in the foot with the Murray Basin debacle. What should be a simple thing (standardisation of BG track) is probably sabotaged from within to fail. And the feds want Inland Rail to succeed and so are not thinking about anything else.
Edit 1: If it makes economic sense, and the Victorians across the border decide to do a small standardisation project and do it properly (which is possible), no doubt the rail freight viability of the run will cause major mode shift, not just Riverina-Shepparton-Melbourne but also Shepparton-Riverina-Sydney and Shep-Riverina-Queensland. There are all sorts of truck volumes going out of the region that are rail worthy volumes, however the inftrastructure has never been properly reviewed to know how viable it actually is.
