My current Idea - a new Cross Harbour Tunnel

In the SMH on Saturday they highlighted their new backing of a Public Transport Enquiry. All grandiose sounding, but the intention is good. They want to take action where successive state governments stretching back before I was born have done nothing.

Of course it could – well most probably will - be a bunch of hot air, but it brought back thoughts I have had for a while, which were reinforced as I spent a few weeks commuting from Wynyard to Chatswood. Obviously there needs to be extra lines across the harbour - 2 tracks on the bridge supporting all those services is not feasible. So I thought why don't they instead utilise the spur line from Waverton down to Lavender Bay, and go underground under the harbour at Blues Point?

This then connects to the new development at Barangaroo. From there the line continues underground to a new station, either at the end of Market Street to connect Darling Harbour or it goes to the new planned "Sydney Square" across the street from the Town Hall - after they demolish the buildings currently there. From there it will connect up with the vacant stations at Central and off on its merry way into the Cityrail network.

Alternatively, I have also considered that this could be part of a line that connects the beaches - the Northern Beaches to Maroubra. Utilising the empty platforms at St Leonards a line dips underground there running north and heads off to Dee Why or somewhere - my geography of the Northern Beaches is sketchy. At the same time, after the new Town Hall station it continues on under Oxford Street to a new station at Taylor Square and then on to Moore Park - for the stadiums obviously - then to UniNSW and continuing to Maroubra.

See my little mock up below.

Now all I have to do is tell the Public Inquiry, they tell the government and it gets built. Too easy.
