Amazing Australian Railways

Australia is not a country but a continent.

Strangely it has only 6 or 8 big cities all along the coast except Alive Springs.

Adelaide
Brisbane
Darwin
Canberra
Newcastle
Perth
Sydney
Melbourne

There is wast stretch of land not inhabited.

It has many type of railway tracks from small gauge to standard gauge.
Melbourne of course has underground train.

The biggest anomaly is there are driverless robotic train in the outback.

Do not panic!

No passengers and these trains carry minerals and coal from outback to the ports.

These are maintained by the virtual computer technology.

I am yet to travel by the surface train.
