Sorry, Didn't know that an entire inquiry could make a mistake and make up reasons like that. There are reasons these inquiries are used. To find out exactly what went wrong, who to blame, how to fix it and how to stop it happening again.
These are used to find out the FACTS, not making stuff up like what you are doing.
When RIC and Countrylink made no attempt to make the line profitable with the loss of freight, and then further pushed it downhill by screwing up the timetable, not maintain it to a standard that could even allow freight. That's what destined the line for failure. It was pushed to that fate over many successive governments, some whom had vested interests in making sure it closed. (very similar to what is going on in newcastle)
Muwillumbah is also rather well situated and could easily have a rail freight terminal. It doesn't have a shortage of potential freight. It would have avoided some of the largest issues with freight along the NCL. (mainly the choke point of ACR to kyogle)
We are spending how many billions of dollars on roads, mainly to cater for trucks when we absolutely refuse to spend what is a tiny drop of money in the large scheme of things, and turn it into something that can create the government money, instead of continuously sucking money from it. Roads don't make money, many toll roads fail to make money. The NSW state government is going to spend 6.4 billion on roads in the next year alone, just remember that most of these projects are predominately funded by the feds. And most local roads are funded by the local councils. In short, the state government pays the smallest amount for road construction and upgrades out of the 3 levels of government
RIC spent less than 3 million in maintenance on the casino-murwillumbah line in its final year of operation. 3 million buys you about 1km of simple resurfaced road.
People in qld are yelling at the government to widen the M1 for only 5km but will cost 220 million. It is only congested during the peak of the peaks and otherwise a fantastic road. And we have all heard the stories of trucks crashing, killing people and shutting roads for hours while thousands just sit in a very expensive rolling car park.
You seem to love economics, but are really terrible at understanding some of the basic fundamental concepts. Maybe you are more of an accountant, just make sure their is less stuff on the books so you can understand everything easier and have less work to do around EOFY
