Couple more photographs today at Corinda.  The yard track is all pulled up, piles of sleepers.

Corinda service via Tennyson shortly after arrival at 4.01pm. 
I travelled on this service, moderate loading (2).

Checked out the Cliveden Avenue road bridge.  Work proceeding to clear the soil right up and under the bridge.
Also noted a number of 4 track overhead wire supports in place between the bridge and Oxley too.

I have been wondering when the new signal gantry between Sherwood and Graceville will be put up. Looks strange laying on the ground for the last few weeks.

I thought it was just going to be a conventional quad Corinda-Darra.  What's the talk of a freight track?

[ozbob]

Originally double to triple.  Shortly after the project commenced it was upgraded to a quad.  The premise being the additional track was for freight.  The 4th line will not be electrified at this time although it is planned to be down the track so to speak.  If you look at the photographs immediately above, the two lines left are the freight line and the siding. There is capacity to hold two full length freight trains there.  The third sub track is extended from platform 2 road.

We have endeavoured to get all four lines electrified and the 4th platform at Oxley constructed as part of the present upgrade.  But not successful.  

[mufreight]

The fourth track will based on the figures from the last rail capacity study which already have been proven to understate the passenger demand be required for passenger services by 2016.
To complete the project by wireing the fourth track and building the fourth platform at Oxley as part of the current project has been estimated to cost $20 million.
It has been estimated that the costs of setting up alone to restart the project will exceed $17 million and by 2015 the costs for wireing the fourth track and providing the platform at Oxley will have risen to $60 million plus more so the cost of $20 million to do the job now as part of the current project will have risen to at least $77 million, another example of the economic skills of the current government and the abilities or lack of them of those planning for the transport infrastructure needs of South East Queensland.

[somebody]

So, yet another place in the network which timetabling has to consider?  Sydney's rail clearways plan was largely an effort to keep such places to a minimum.  I guess a 4-5min section Darra-Corinda you should in theory be able to run 6tph to Richlands without using the existing pair of tracks.

[Derwan]

Something I've been wondering for some time.

Could it be that the 4th track was funded (at least in part) by the corporate arm of QR to ensure the steady flow of freight trains (maximise revenue) regardless of peak exclusion periods?  Perhaps it was in their best interest to provide funding as part of the track upgrade that was already planned.  (I.e. it's cheaper to add a 4th track while they're adding the third track.)

Could it also be that the agreement was to build the line without electrification to ensure uninterrupted freight passage - at least for a certain number of years - after which the Government would have to provide the funding to electrify the line and provide additional platforms?

[ozbob]

Good reasoning Derwan, but it was the alliance that came up with the 4th track strategy, which I might add is far better than the original proposal.  Despite the efforts of many to gain enough funds to do the 4th as an electrified line for the very obvious long term savings it was not possible.   

Incidentally there will be a partial electrification of the 4th line from Darra towards Oxley to a point about the brick works I understand.  This will be necessary to allow the trains to come over from roads 1 and 2 which will the Richlands (Springfield) roads.  That was part of the original plan as at that point the 4th line down from Darra was to converge to the three lines. Now the 4th line continues on. Will be interesting operations though. I am sure I will see 4 trains all pass by at once when it opens!

It is time for our freight lines to be given thoer own dedicated, non-conflicted/excluded lines linking our ports, major rail lines and inter-modal sites.
