Hi Bob, I am going to give it a go today bending a strip of 12mm ply to one of the curved sections as a temp plate has a 7foot radius curve., I use the same method as well still waste some ply though.
That corner scene is coming along well great painting effort on the back scene, looking as a back scene behind the bridge on my layout
Still can't decide on what bridge to build, got one in mind has 7 piers and older double deck bridge built in the 70's,the cable stay bridge was built 2009 modern design and only two main piers, but huge towers 7foot high.

Hi Bob, I successfully had a go at bending a piece of 12mm ply to a 7ft curved ply base, a lot of clamps will work.
The ply has to be that soft ply, be great on making curved viaducts a matter of sanding the arch smooth and a bit longer time wise actually be stronger as well .

Making some structures at the moment from wood products.
A small skip fed loader is under way ,based on one in the Hunter Valley.
Some scrap balsa and a corrugated card (not designed for modelling) that was given to me are being used to start.
Cheers
Bob

Hi Bob how are you going with your coal loader project, I will be back on my layout construction Monday, turning a couple of pens on Saturday, haven't done any turning for 12 months, got to keep the turning skills up.
Going back by train to Sydney I spotted signal box still in use.

I passed that box many times.
I have more than one structure on the go at the moment.
The blue fibro shed was just built and inserted with other junk into the loco shed scene.

Coming along nicely Bob, yeah lots of work ahead, are you modelling the coal loader on a proto type coal loader.
What's it like where you are , still has that nip in air up here to a nice spring day 23 degrees.

Last I looked it had scraped up to 14C but the cold breeze makes it jumper weather still Tony.
The coal loader is loosely based on a photo of one in the Hunter coalfields years ago. Can't remember where at the moment.

Hi Si,
have a look at http://fourwheelsnoaircoal.blogspot.com.au/ for details and differences between the Hunter district hoppers like Bob's and the Illawarra district wagons as used on Corrimal with fixed hoppers.

They still need weathering lettering and numbers - The design of and build of the standard gauge wagons and the screens details are still to make their appearance on my Corrimal thread
For Bob, scroll down to see some photos of the Stockrington loader.

Hi Bob, I did come across a link on a coal loader around the Hunter Valley you can clock on the pics to make them larger and best sending the link
http://fourwheelsnoaircoal.blogspot.com.au/2009/05/hunter-valley-coal-wagons.html.
Nice lot of pics of your coal loader John, good to have other working siding on a layout.
Still cool morning up here yesterday was cold in Brisbane and windy people were wearing jumpers.

Hi John, I hope you had a good time at Sydney.
Your model is very inspirational.
Yes, that photo collection has some great shots in it.
Mine is a combination of ideas, part Duckenfield 5, part Minmi, i.e. a skip fed bin in a cutting, very much reduced in size to fit the area available. Pictures in Giff Eardley's original book on J&A Brown gave me the general idea.
Yes, they are Australian coal hoppers Si. Mine are one of the private Hunter Valley types and I think John's are NSWGR ones. The removable bins with bottom exit were invented locally for loading into ships berthed upriver in the Hunter Valley. They could be lifted over to the boat, lowered and emptied or be rope hauled up to a delivery chute and then emptied while still in the underframe.
I have been working on the cutting for the coal loader scene. I am using soft rocks for this one.
cheers
Bob

Duckenfield 5 is shown on page 125 of 'The Railways of J&A Brown' if you have access to a copy John. Tiny photo.
I think I can safely say that loco is ex NSWGR no 20N. A Kitson product circa 1870.
I know more than one was excited when that photo collection came online some years ago. Some interesting shots in it not seen elsewhere.
cheers
Bob

Hi John and Bob,
I was down your way a couple weeks back, possible could of flown over Unanderra on our way to Canberra, wasn't long enough stay, only stayed over night, mainly went to the AWM, was awesome need two days to go through the memorial.
What do you know about Little Bertha the German rail gun only the main gun is left, would like to scratch build the gun.
WE went back to Sydney by train 3 and half hours of pure magic, how far are you from the Canberra to Sydney line, I had a couple of hours at Sydney Central station took lots of pics as I am modelling the station building, my Sydney Central be cut back width wise, still b awesome size when built.
Bob your cutting is coming along nicely, what do they call when they back fill a gully to level the track bed, the Canberra line had a few of them and fairly large curves as well.

Tony I don't know of any specific term, it was just a fill to me. They tried to balance spoil from cuttings to fill the gullies when building lines.
The Amiens gun was ex warship placed on rail underframe. Sadly the underframe was ditched years ago. Hard to miss at the War Memorial. You could take several days just to properly look over the WM. If I was doing some work there I would often time it so I had my lunch there and could spend some time exploring.
There are probably plenty of photos on the web that might help you to build one, also look at the 1:35 plastic models on offer, there might well be one there that might give you some ideas to make a HO one.
I think I have seen at least one made in HO years ago for a layout.
cheers

There is a photo of the gun in the ARHS book " Railways of the Canberra and Monaro Districts".
You never know they might have a copy at the AMRA library if you are lucky Tony.
Cheers

Hi Tony,
in answer to your questions -
According to wikipedia, the "Big Bertha" name has been incorrectly applied to German rail guns of WW1
I thought that Big Bertha was one of 5 rail-mounted guns used to shell Paris and other parts of France during WW1. The Aussies captured the gun.
For the Aussie "Big Bertha, my understanding is that it as was sent to Australia at the end of WW1/early 1920's. The gun carriage also made it to here but was cut up in the 1920's/1930's, so only the barrel is preserved at the Australian War Memorial WM see https://en.wikipedia.org/wiki/28_cm_SK_L/40_%22Bruno%22
You may have missed you best chance of picking up more information in Canberra either at the AWM archive or at the National Library where one of the larger rail photo collections is now held. Did you remember to take a photo of the placards beside the where the barrel is displayed? There was some good information on those.
Moss Vale was as close as you would have got to Unanderra. There is a line that comes off the Main South there that heads downhill to Unanderra. Part of that line is one of the steepest mainline tracks in Australia with a falling 1 in 30 grade. There is no regular passenger service on this line.Last edited on 16 Oct 2016 12:10 am by oztrainz
