Outer Harbor Line - T2T Overpass

 
  Pressman Spirit of the Vine

Location: Wherever the Tin Chook or Qantas takes me
Noted the following dates during a scan of the T2T project website

Temporary closures of the Outer Harbor rail line for the construction of a rail overpass over the lowered motorway and the South Road surface roads.
The scheduled closure dates are:
5 and 6 November 2016 (weekend)
2 to 22 January 2017 (3 weeks!)
25 and 26 March 2017 (weekend)


Looks like the overpass will go up during January next year

For you interstaters the T2T project is the River Torrens to Torrens Road upgrade to South road

Well, in the T2T fly-through video on the DPTI website, it has at least 3 spans!  If the Port canal had been built, would we now have an aqueduct over South Rd?

Will the signalling cables be run via-a-duct too?

Some photos taken last Thursday of rail related progress at T2T.  Easier to photograph than flying sheets of steel or exploding CB's.

I understand that the new flyover will be in operation after the January shutdown also that staging works for the other Torrens project, Torrens junction, will take place to use the T2T closure.

As of this afternoon 14:30pm 4th Jan
The rail has been cut and removed, the eastern roadway is being excavated through the old rail alignment.
Bridge sections appear finished ready to be lifted into place
South Road will be closed to all traffic this weekend (7pm Friday to 6am Monday) so the bridges can be placed and a new temporary road diversion opened.

Afternoon, 4th Jan 2017. The attached image is taken from the Queen St level crossing

The 400 ton capacity crane in the foreground and the (350 ton?) unit behind it have placed the initial bridge members on robust foundations.

A stream of trucks, and earth working machines were filling between the concrete walls to form the bridge's ramps.

The first span of the T2T overpass was in place by 4pm today (8 Jan 2017).

One person watching the works said that he was told that the span weighs 268 tons.
This would be in keeping with the big crane which can lift 600 tons as long as it's reaching less than ten metres.

Track is now in place on overpass.  A ballast regulator and a tamper were working on the down track this evening.  Some track work was still going on on the Coglin St ramp on the up track which has yet to be be tamped.

There have been three different sets of machines in use during the closure.  The DPTI machines have been at Woodville, Downer machines at T2T and Coleman Rail doing the level crossing work at Hargrave and Gedville Sts and the Port River Bridge.

I've uploaded a video which shows the works on the Torrens to Torrens project to date, including the rail bridge.

Looking good for tomorrow.  3018/23 were shuttling hourly between ARS and the branch platform at Woodville this afternoon.  Seemed to be for route familiarisation rather than track testing.

Thanks to a heads-up from Alex C, I got a shot too.

Probably part that but more like to wear the rust off, of the rails on the bridge as all new rail and sleepers were used on it. It was all stockpiled along side the track just after Croydon Station going towards Adelaide before it was used. Sleepers and rails by the way.
Also probably to ensure that the signalling all worked again as well.

Quite the opposite David. Many more runs would be needed for route learning than the couple needed to scrub off the surface rust, presuming there was any rust left after the tamper had been over it.

Why would they need to learn the route it has not change at all only two minor grades installed in it. All the drivers cover all lines and going up and down a slight hill would not be a problem as they do it elsewhere without problems. Goodwood underpass Belair line etc. I don't really think any of us really know the reason for it though. But you have to remember also that the trains have not run along the whole track for 3 weeks so all the signalling circuits on the whole line and the undisturbed rail sections would need the rail top to have the rust removed from it during the down time. Also to test the signalling circuits activate as well. We have had some good rain during the period the trains were out.

On the first day of service I had to go to St Clair station and there was a fault there by the way the level crossing was stuck in the down position and had been for some time judging by the road traffic build up there. I was there about 1 pm. I went to Bunnings and was there about 1/2 hour or more and when I returned to St Clair station the level crossing was still down and holding up traffic. About 5 minutes before my train was due they finally got it to go up and 5 minutes later the train I had to get set it off again, I did not see if it went back up though as it was a three car set and I got on the closest car with what I had bought which was the middle car.
