It's great to see plans working, everyone moaned when the infrastructure was being built that it's too expensive and everyone moaned that transition to renewables is too slow but with the systems in place we've reached the point of rapid uptake and are witnessing a sea change.
We're now at the point we're going to start seeing coal transportation decline to the point that established lines close, ports redevelop coal infrastructure into general purpose cargo or close all together, meaning the freight line feeding them stop and coal nines only have local industry to sell to - smelting works for example. Coal is horrible to transport and it'll be great to remove all that heavy machinery and dirty work, replaced with some simple straps of copper running underground.
