Uncompleted Railways

["Garry Hoddinett" <hoddos@netspace.net.au>]

Can anyone give information on any railway were a SUBSTANTIAL start was made on construction but work stopped and consequently no track was laid?  In New South Wales I can think of the following railways:

 

Casino -  Tabulam: 

Formation substantially completed but no track laid.  The remains are readily observable from many locations along the Bruxner Highway.

 

Guyra - Dorrigo:

Formation visible for a few kilometres to the north east of Guyra.  How far did the earthworks go before construction stopped?

 

Gulgong - Maryvale:

Formation constructed, a tunnel bored and some bridges started.

 

Maldon - Dumbarton:

Formation substantially completed from proposed Avon Tunnel to Southern freeway.  Some bridgework started on Nepean river bridge.

 

Bradfield's Eastern Suburbs railway:

Tunnels constructed from SE corner of Hyde Park through St. James to near Macquarie Place.

 

Are there any others?  Any similar "railways" in other states?
