This map of Scenic Rail Melbourne shows a closely spaced network, with stops typically within 500m. The network comprises 1,745km of two-way 10m high guide-rail on poles, but otherwise with the same functions as for the previous map.

It is surprising that to reduce the stop proximity from 2km to 500m only requires an increase in network length from 733km to 1,745km, and that is achieved by using a tree form, directed at local centers.
This finer network would be more convenient, and may even be profitable with more optimistic estimates, and the network should be staged with the highly profitable 733km basic structure to generate finance for its expansion. But walking or riding for the last 500m still requires protection from the elements and bikes, electric scooters and wheelchairs will still be required, so the 2km proximity initially is recommended.
The basic rural network follows.
