Where is or was the Illeroo Block Section

I am wondering if anyone is able to identify where the Illeroo Block Section was (or maybe still is) in South Australia.



A couple of years ago I purchased some modern railways signs at auction.  Three were large reflective white aluminium panels 70cm x 70cm with a location name followed by the words “Block Point” all in black capital lettering.  Two of the signs were for the locations “Eucolo” and “Renton” which are both on the Port Augusta to Perth line.  (Eucolo is between Pimba and Lake Hart, while Renton is between Kingoonya and Ferguson.)



The third sign is for "Illeroo" but I have been unable to find that location in any current online ARTC schematics.



The centre of the district of Illeroo (post code 5715) is about 30km directly west of Port Augusta.



Myall Creek runs through Illeroo and the Port Augusta to Whyalla line crosses Myall Creek about 35km out of Spencer Junction.



However, Illeroo isn’t really that far from Tent Hill, Hesso, etc on the Perth line, and so it could have also once been used as a name for a block section on that line as well.



Having come with the other two signs from the Perth line, I initially assumed it would have been from there, until I found the very tenuous association with Myall Creek which raises the (slight?) possibility of it being on the Whyalla line instead.



Anyway, I look forwarded to any information which people may be able to contributed to determine the location of Illeroo,



Cheers.

I just checked the map showing Illeroo... is it possible that it is referring to a section on the Whyalla line? I am seeing the eastern edge of Illeroo as being closer to the Whyalla line before it goes under the Eyre Highway than it is to the Trans line! Many sections and Stations are named for places that they are "ridiculously far away from" if you think of where they are supposed to serve in Australia. I lived in Melton for a long time but the railway station was actually in Melton South, on the Bellarine where I now am, the old Ocean Grove station site was nowhere near Ocean Grove... it would have been a couple of hours walk!

Hope this helps you

'.........  Myall Creek runs through Illeroo and the Port Augusta to Whyalla line crosses Myall Creek about 135km out of Spencer Junction.'

Perhaps 35 km as the Myall Creek crossing is roughly half way between Port Augusta and Whyalla which is ~ 76 km.

Off thread I know but in case of any interest the 476 feet Myall Creek bridge consists of (2 per span) 30 inch x 10.5 inch universal beams with a 10 inch concrete deck on cylindrical* column piers.

* Due to the angle at which the railway and the stream intersect.

YM-Mundrabilla you are correct and I have edited my original post accordingly.  Thanks for pointing it out,

According to my sources, what you have are block point signs for the proposed roll out of ATMS between Spencer Junction and Tarcoola.
Due to the high TOW workload and the delays in ATMS rollout, the project was shelved for the time being and interim signaling was installed.
Eucolo and Renton are now intermediate signal locations, but Illeroo (we think between Tent Hill and Hesso) was considered unnecessary and dropped from the project.

Other current intermediate signal locations are: Mason Creek, Lake Hart, Palpinna and Wilgena.

Hope that helps you!

Sorry, but who or what is TOW, please?

Many thanks.Smile
Do I therefore understand it that whilst crosses are (obviously) not possible that Train Orders can be issued up to and, perhaps theoretically, between Block Posts?

Thanks to everyone who has contributed information so far.

Trevor (xdford) - yes, I was wondering if Illeroo might be associated with the Whyalla line as well.  It was when I first realised, as I noted above, that “Myall Creek runs through Illeroo and the Port Augusta to Whyalla line crosses Myall Creek about 35km out of Spencer Junction” that I thought this could be a possibility.  Currently the only block point on that line is Lincoln Gap.  The entry in Wikipedia for Lincoln Gap states the formal boundaries for this locality were created on 26 April 2013 and adjusted on 25 September 2014, so I also wondered if it was called Illeroo before it became Lincoln Gap Block Point.  However Big Mikado’s remarks show otherwise.

Big Mikado – thank you, your comments are very helpful.  I purchased the signs at auction in November 2018.  (Does this fit in with the delay in ATMS and the installation of interim signalling?)  I thought it odd that none of these signs had holes in them.  The holes would of course come from bolting them to a post or fixing them to some other surface, so the lack of holes is consistent with your information that the project was shelved and, presumably then, these signs were never installed.

Lincoln Gap and Roopena (19 miles and 32 miles from Port Augusta, respectively) were both crossing loops back in the days. If Lincoln Gap is now a Block Post I assume that the crossing loop there, at least, has been 'upgraded into nothing'?

SAR On track: Yes it does fit in with the timeline. Your signs are brand new.

YM-Mundrabilla: Correct! Block points allow a following train to enter the section once the first has reported past the block point.

Just in regards to the Whyalla line. My sources tell me that the LGP crossing loop was closed around 2000. Roopena was always just a goods loop from the opening of the line. It was only recently upgraded to a crossing loop for ATMS testing.

The only other intermediate location on the line was a ballast siding between Spencer Junction and Lincoln Gap, used when the line was being built. It's clearly visible on Google Earth, about a km North of the Eyre highway overpass. I'm told it was used for wagon storage for some time before being closed and removed.
