2015_02_15 Rained yesterday
Very Humid today.
At 8.30 am I had breakfast whilst checking my mail and my groups. At 1830 I went for dinner with the family and nothing got done.
The work bench was all set up for sound installs. Two pristine C Class were ready to start!
5 Auscision A and B Class were laid out, stripped ready to file and fit speakers.
And if that was not enough a heap of T's Y's and X's were in need of.... eh? mo...sound ;)

But nothing much happened :(

My sugars are rising and yesterday I did walk nearly 6 km with two serious "gasping" hills along the way. It was 7.00 in the morning when I left and I did beat the rain. Along the way I found lots of blue gum trees in our area. As you would have noticed, I did not think we had any around here.
In fact about one in 10 are blue. Fancy that?  But stand back and take a group shot (tree groupie?) and they all look decidedly green.
So I learned something. The main thing for me, though is railway lines in the North East do look as if they have green gum trees :D

2015_02_12 Gum Trees

2015_02_12  ah!! now its hot :)

Went on line and tried to fast track some gum trees, but unfortunately Queensland gum trees are not like our gum trees at all :)

With apologies to this E-Bayer whose photo I have stolen, and pointing out too, that he is an example of every tree manufacturer I have found so far, even Auscision!
Auscision Trees
These are by far the best I have found but still not dense enough and at $16 to $30 a tree much beyond what I can afford.

So what do Gum Trees look like?

They certainly are not this colour from Scenery express.com

But outside my home, all I can see is real Aussie gum trees :) They are not blue!
Why do Mountains look blue in the distance as seen in these pictures?

"The Blue Mountains, given that name due to the blue haze that hovers above them, is an area renowned for spectacular scenery, plant and wildlife and densely populated forests of oil bearing Eucalyptus trees. Thus, it is commonly believed that the blue haze blanketing the mountains is created by the atmosphere whereby dispersed droplets of Eucalypt oil combine with dust particles and water vapour to scatter refracted rays of light which are largely blue in colour.

However, because this is a common phenomena shared by mountain ranges elsewhere in the world, another theory suggests that:

the sky is blue because tiny air molecules of oxygen and nitrogen, water molecules, and dust motes interact with light. The small size of these particles means that high-frequency light (like, blue) is much more likely to interact than low-frequency light (such as red). The interaction scatters blue light in all directions. Consequently, we are more likely to see blue light than any other colour. Thus, the sky looks blue.

Consequently, distant dark mountains reflect little light to our eyes. Our eyes receive much more light from sunlight scattered by tiny molecules between us and the mountain. That scattered sunlight is blue. So, it isn't a scattering of light reflected from the mountain that makes the mountain appear blue, but rather a scattering of light between us and the mountain. (WeatherQuesting Web Site)"

At the distance the long leaves are not noticed. I dont know if anybody can make HO gum leaves?

Almost all the pictures had the sun behind me except the one over the horse float.

So what do we do? I know make our own :(   The colour is three toned to my eyes a mid green and dark green with just a hint of red (brown?) not looking at trunks which can be any colour :

2015_02_02 Search Engine :)

2015_02_02

Not a lot of stuff that I could post the last week or so. Mainly because I have been sorting through the temporary wiring, removing Tail light short protectors, and wiring no longer needed and setting up the NCE District circuit breakers.  Time consuming but really necessary, because I need to tidy up the wiring and secure it under the deck, out of sight, before I can install my LED lighting strips.

At the same time I have had a persistant short that trips the DB150 Command station every 30 seconds or so. Trial and error searching. First isolate command station, then add one district at a time till I find the cause. Because the Branch line is already connected to two NCE Circuit breakers and all tail light protection has been removed, I left that till last. After all I had already corrected many wiring errors caused by old wiring left in place after new wiring was added in its new roll as a fixed layout branch line.

However after reconnecting, and repairing all the sections, the persistent short was found to be in the Trentham to Bularto branch sections.
So today I started unplugging and testing all the droppers. I have not finished, however just before I came inside tonight, I have the positive feed connected to the to the Trentham side NCE breaker, without the fault. As soon as I connect the negative feed, I get the short. So I have an unknown connection on the negative return between the top level track and Trentham, or a cross feed between Trentham and Bularto.  Should not take long to find it now.

As well over the last 15 years I have been collecting RUB cars so that I can make my Daylight set. I have found about 6 cars and at least 12 are still missing. And so I started searching for the missing cars, because I have a friend who has found someone to build them for me.  But over all these years, I have no idea where they may be. So earlier today I began opening boxes and searching. Whilst doing that I found stuff I had forgotten I had. So as I need to clear a space for the installation of the branch terminus, I started moving stuff around in the boxes and stacking them up under the layout, to clear some room along the front wall.

Yes not much to show, but I did find 15 Locos that need DCC chips and a few to sell as well.

Mostly empty boxes, but I want to keep them so that in the future, my kids will have them when they sell off my stuff.
I did move about 20% of this pile to here...

Australian Rolling stock not on layout, and others that need work done before commissioning :)

Here is the BG coming up the grade off House Creek. The gradient is too steep for Austrains T Class and the Auscision one as well.  I cut the supports down to soften the gradient and smooth out the climb.

First lifted out the track, removed the screws then using this nifty tool, easily took 2cm out of the bearers to smooth out the grade.

This is as much as I can take out without exasperating the grade to the top of the hill. However  the T Class still stalls. A two dollar coin laid on top of the T was all it needed to climb the hill. I will have to lower the summit over top of the  Albury line, to get it right. But I wanted 10.5 cm clearance and that will mean I will only have 8.2 cm, not enough for Double stacks, which I thought someone might want to run. but not now I guess :(

Under the wayward SG track yet to be laid you can see the track bed heading to Albury. Directly above it just this side of the white wire hanging down the high point of the top level needs to be dropped 2cm or so, you can almost see the hill in the pic?

So nothing stopping me from installing the 46" radius SG track to the Loop points about 3 m around the corner and that completes all the SG track that I can lay at this stage.

Then I need to wire in all the yards and finish installing the circuit breakers and points.

Now I must find a home for all the boxes in the corner and I can start installing bench work for the Branch Terminus that friend Tony donated to the cause.

But that will have to wait for another day :)
