Crank the welder up to 120 amps and see how good my welding is.
All that practice building railroad cars is starting to pay off. This could be a goer.

Back in operation!  Welding seems to be good so it's back to track prep. The material in the cutting is very dry and doesn't compact well so I will wait for some rain before resuming.
Meanwhile the promise of some steel beam has been withdrawn so the bridge is on hold while I save up (or collect on the sold cow car)
It has been decided to extend the new track to the next triangle at Canungra and use the bridge materials there instead. This adds about 1000 feet to the railroad and nearly doubles the run length and adds four stations.  Any further development will depend on my enthusiasm and depth of pocket. (currently the pocket is zippered shut!!)

The start of the triangle at Canungra. This is on top of the cliff overlooking the creek with some great views when the trees have had a haircut. Headshunts will be at least 30 feet so that entire trains can turn

Typically an Escape Track / stub end ahead of a switch to allow an engine room to run around it's train.  
 
I think here our friend is talking about the tail tracks to a wye........ but I could be wrong.

Exactly what I would have said: A headshunt is the tail of the wye, and a triangle is a wye.
I love these linguistic differences. When I was travelling to Japan (sadly I didn't make it to OZ) a local, who worked for the same multinational company, told about an international sales meeting in Japan. He (whose native language was Japanese) had to translate English between the Yanks and the Aussies, who couldn't understand each other!  For that matter, there is a guy at my work from South Carolina that I can't understand. Nobody else does either, unless he slows way down or we have an interpreter.
 
Fred,
Let me say how much I enjoy following your posts about the track you are building.  Many daunting obstacles to be overcome, but the results are very impressive!

I have a book that is a Chinese dictionary of engineering term that I got my first year in Taiwan.  The handy thing for me was that it has each term given in Chinese, Japanese, German, French, American English and British English.  Other than using it to say, I mean this one to local people, my main use was at the time I got it working between those last 2 since we followed a British company on the project and once you get below the rail everything has a different name.  The definitions were in Chinese.  There were also some sketches.  I was going to get some copies for new arrivals but found that it was out of print.
 
Most of us here probably know the basics but far from all.
 
rail=rail
rail web=fishing surface or fishing
rail base=rail foot
joint bar=fishplate
track bolt / joint bolt=fishbolt
tie=sleeper
tieplate=baseplate
spike=dogspike
ballast=ballast
subballast-sand blanket
space between tracks in a multiple track lines = six foot
space between rails is gage side of rail = four foot
 
Then of course the one at hand:
wye=triangle
 
Spring switches are uncommon outside the US & Canada
Spring frogs are so far as I know unknown outside the US & Canada
 
there are more but this is a good start

Geez Tom, see the trouble you cause when you don't pay attention in your English lessons
I looked up headshunt in the google, and one of the definitions was " a tube placed into the brain cavity to increase blood flow"
 
A wye is a set of points that diverge at equal angles.
A road is the choice you make about which track to take.
A stub is the bit you throw out of the window when you've smoked the rest
Tail tracks is what kangaroos leave behind in the dirt.
You turn trains around on an "angle"
 
 
 
Now, what was the question!
Pete

Solid red is existing, dotted red is in progress and the green dots are the future balloon loop which may or may not get built (some checks with the lazer level show huge change in height in that area.) Yellow is haul road, to later become walk paths.  
Meanwhile the excavator is back hard at work digging the cutting following a little rain (almost deep enough for a tunnel, but I don't like tunnels, too many bugs!)

The cow car is sold and paid for, so I can backtrack and finalise the waterfall  bridge. This is my inspiration, but I want to use trusses on top, as was common in the outback., A thin pipe handrail will sit on top, as a safety barrier.
These panels scale at 15 feet by 2 feet but the creek is 15 feet minimum and 20 feet to be safe.

Discovered that I can get "I" beams in 20 foot and 30 foot lengths.  If I make the bridge in 2 panels of 15 feet then I can use smaller steel sections. However the track is curved after the first 20 feet.
Solution is to mock up a panel layout on the existing trestle to see if a curve is possible without taking out the legs of train travellers.

That seems to be OK, so paint a panel on to a photo of the trestle and see if it looks OK.  That does it, 2 15 foot panels it is, and a lot more care needed with the footings as they will be right at the water's edge. What do you reckon?
  Doubled 6" I beams, 1 1/2" double angle frame, 1" x 1/8th for the lattice.  1 1/2" x 5"  deck boards with a little gap

Remind myself that it's 3 years since the first rail went down, I'd better start getting serious soon.
There's steel in the shop and neighbour Ron came round and gave a hand. I spent a bit of time giving some welding lessons, it's surprising how your own work improves when you are showing someone else how to do it.
 Now there's 2 lattice bridge panels done, and 2 to go.

Out in the bush, the approach for the bridge is taking shape. There's 35 feet of trestle to get down off the bridge.
There you go, Bobby T, two pictures with people in them

Bridge construction advancing. 2 out of the 4 trusses done and beam brackets on plus a coat of "structural silver" paint

No vehicle access to the waterfall, so the disconnects are getting seriously tested. Passed with flying colors. I wonder if the beams will go as easy.
