anywhere that has hard big industry fail or shut down will have unused tracks
the kalgoolie gold rush of 1893 led to loads of towns springing all over the place
some had rail roads
but once the gold ran out everyone walked out
my granddad said they used to drive up there in the 40s and u could just walk into these places and it was like everyone just stood up and said thats it lets go
fully stocked houses
a few old cars/trucks that still ran many that didnt
now with new tech the boom is back on
but with the ground water being 30 times saltier than the sea there's not much left
and if u did find a rail road then its just ded straight for 100s of kms though dessert
its odd to think that old steam engines used to travel down the train lines bringing in loads of hopeful people
then dragged out those same broken people
now after just laying down new track in the same spots theres huge deisel elcetric locos pulling upto 7 kms of train filled with all kinds of stuff
i love going to old abandoned industrial areas
out of intrest some of the big industrial areas that collapsed like detriot
there would be loads of rail layed by companys that have been broke for a very long time
who owns those tracks now?
EDIT
the tracks a few km from by place service a few of the cbh grain depos
these thing are seen cruising the lines in the off season
doing track maintenence and what not
