The previous blog post outlined a revisualisation of the rail network with Parramatta at the centre. It also identified an outer orbital and also a middle ring orbital. But in Parramatta's case, does it have an inner orbital? Is this a "missing link" in the network.
In the case of Sydney CBD, a inner orbital is formed by the "city circle", ie: Sydney CBD does not comprise a single station but instead has a number of stations linked into a "circle". So what is Parramatta's equivalent of a city circle?
After some thought, it's clear that the inner orbital for Parramatta comprises:
* Western rail line from Westmead to Strathfield
* Northern rail line from Strathfield to Rhodes
* Olympic Park reserved light rail corridor (currently bus route)
* Olympic Park heavy rail station
This is now what the resulting three orbitals look like:
This now completes the Parramatta-centric rail network. The outer orbital comprises mainly double deck heavy rail. The middle orbital is Sydney metro for the most part although the section around Blacktown is a bus link/T-way. The inner orbital is then predominantly the Olympic light rail reserved corridor. The previous situation of radial lines not quite converging on Parramatta is also now resolved, in that they now converge on the Parramatta city circle.
