NSW Rail, http://www.nswrail.net/locations/show.php?name=NSW:Gresley shows a WWII era temporary crossing location named Gresley between Deepwater and Bolivia. It is stated to be at 731.000 Km. From looking at maps I decided an area which seemed most likely due to a significant straight roughly half way between Deepwater and Bolivia. This not where the NSW Rail map fragment indicates. The Grade and Curve diagram at http://www.coalstonewcastle.com.au/infrastructure/003/document/ see http://www.ipernity.com/doc/grahamh/46010316/in/album/1034838 (P227 of the document) shows the location I guessed as the straight on the 1/75 grade shortly before the high point between Deepwater and Bolivia. Converting the miles on the diagram agrees with the 731.000Km from NSW Rail. My initial curiosity about this location came from the 2017 part of this thread https://www.railpage.com.au/f-t11362177.htm
On two recent trips to Tamworth I visited the area until accompanying family insisted it was time to continue the journey. The first visit included finding a culvert marked with 730.???Km http://www.ipernity.com/doc/grahamh/45993394/in/album/1034838 which told me I was where I wanted to be. Also the terrain didn’t contradict the aforementioned high point, and the track from Deepwater has the correct curve http://www.ipernity.com/doc/grahamh/45993392/in/album/1034838 . On the second visit I walked a little way south from the location and found a culvert marked 730.581 http://www.ipernity.com/doc/grahamh/46018122 .
The location included the usual for this line perway concrete markers http://www.ipernity.com/doc/grahamh/45993464/in/album/1034838 & http://www.ipernity.com/doc/grahamh/45993468/in/album/1034838 . Two other constructions are interesting. First I found a piece of rail as a post which is still painted except for an area which may have a sign such as ‘Shunt Limit’ http://www.ipernity.com/doc/grahamh/45993400/in/album/1034838 & http://www.ipernity.com/doc/grahamh/45993398/in/album/1034838 This is towards the southern or Up end of the location. The second is a concrete block in the ground further north which I speculate could have been a ground frame foundation/base http://www.ipernity.com/doc/grahamh/45993426/in/album/1034838 . Suggestions of alternative explanations welcomed.
Along the eastern side of the track there is a vague ground shape which could be old formation with a drain on its eastern side. This is most noticeable at the730.???Km culvert http://www.ipernity.com/doc/grahamh/45993462/in/album/1034838 and further north at a small bridge structure. http://www.ipernity.com/doc/grahamh/45993430/in/album/1034838 http://www.ipernity.com/doc/grahamh/45993432/in/album/1034838 http://www.ipernity.com/doc/grahamh/45993434/in/album/1034838 (no Kms visible here). I didn’t notice any sleeper-shaped depressions in the ground or stray dog spikes on or about this formation though I didn’t put much time into it.
Beyond the bridge the siding works appear to follow the terrain where the main track rises above the terrain on an embankment.
http://www.ipernity.com/doc/grahamh/45993490/in/album/1034838 . In the same area as the siding works end the eastern fence line makes a right angled zig zag bringing it closer to the track http://www.ipernity.com/doc/grahamh/45993496/in/album/1034838 . Also in this area is a culvert marked with 731.606Kms http://www.ipernity.com/doc/grahamh/45993518/in/album/1034838 & http://www.ipernity.com/doc/grahamh/45993522/in/album/1034838. This is from the eastern side which has no sign of having been duplicated. View from the west showing same culvert and embankment, curiously showing a 1 metre difference http://www.ipernity.com/doc/grahamh/45993528/in/album/1034838 .
Dense vegetation growing in the track prevents visibility further north http://www.ipernity.com/doc/grahamh/45993512/in/album/1034838 & http://www.ipernity.com/doc/grahamh/45993506/in/album/1034838
There is plenty more I’d like to check out on future visits.
