Maybe there just isn't much to say. It has been previously declared that mvhr expenses exceed receipts. The group has multiple steamers and 40kms of track to maintain. The township of gympie is not a metropolis, and skills and resources for a large group would be limited in this regional area.
I suggest mvhr is yet to face its biggest issue: sustaining 40kms of track. I think that will eventually become too big a task, without outside intervention. If the group does not get (more?) assistance with track work, i think they will have to truncate to amamoor. At 23kms from gympie, that is still a significant length of track to look after, but there is a usable turntable already installed there.
Obviously, such a decision would be taken reluctantly. Having ridden and filmed the rattler, such an outcome would be disappointing. But, if a mere armchair observer living nowhere near gympie can see these issues, then its just a matter of time before they have to be addressed.
But as Keynes apparently said, the markets can stay irrational longer than you can stay solvent. And we are all Keynesians now, apparently.
