David has been in touch again, and he has very kindly taken the trouble to answer your questions posted in the comments.
If you want to get up to speed, and see his first post, it’s here.
Thanks again for your blogs and also to those that sent me such kind comments.
I notice that there were quite a few questions, so will attempt to answer some of them here.
I have included some more pics which may assist with the below explanations.
“KARRAWIDGEE” uses Peco code 100 set track points ( turnouts ), some set track pre-formed pieces and flexi track.
The layout splits lengthwise down the middle and runs along front side of loco shed which created some problems with joins to get track into loco shed on back half.
The track plan just evolved. Initially I had one outer oval, then played until eventually it all fitted inside the first oval.
The smallest radii ( curves) I used was #2, 438mm. I was amazed at how many configurations would have worked. See photo of control panel for track plan.
I was determined to have an elevated coaling facility and the result over loco shed was the result, as nothing else would work, no room below.
The 4 dead ends on the right hand side are intentional, designed for further expansion of the layout. Because “KARRAWIDGEE” occupies the space needed for the next layout it had to moved on and the new owner will use those dead ends to connect to his other larger layout.
Because I could not fit a turntable on the layout, one track on the right was used to provide loco turning and transport to programming track via a “loco lift”
The back dead end in tunnel I used as a loco shed to store a loco out of dust. Wig-wags flash and sound is genuine 1950s bells.
The white fencing at the pedestrian track crossing is how any Victorian Railways uncontrolled crossing is designed and this is still in use today but made from galvanised iron not timber. You cannot go straight ahead onto track but must deviate left or right and return to cross track.
The track work is all ballasted including the bridges, faithful to the Victorian Railways method of bridge building.
They decked the top of the timber trestles with side boards and then laid the sleepers ( ties) on the deck, then ballasted. Other states in Australia did not use this method.
All the electrical components are hidden, if possible, the signal box and timber platform extension are hiding switches.
The photos show the method I chose to gain access, if needed,
by having lift out panels.
The backdrop lifts off if needed and the sides and front (clear acrylic ) are what I call” anti -damage barriers” as I have found it so easy to do damage when leaning over the sides. I have knocked the signals repeatedly.
My signals are now held in place by drilling up through the baseplate and another matching hole in the ground into which is inserted a piece of bus wire and signal inserted on top.
This gives a loose fitting which moves if knocked and has so far served me well, as against a rigidly glued item.
The vegetation was all individually planted and colored out in natural daylight with acrylic paint.
The trees are made from the CEDUM plant which bears a strong resemblance to our Eucalyptus trees.
The shrubs, bushes and groundcover all vitamised foam rubber. The terrain is white styrene packaging foam, usually got for free (see lift out panel photo ) smeared in Gapfiller, hot wire cut, shaped etc.
I do lots of experimentation with techniques and materials.
The loco shed is the only building illuminated so you can watch to park your locos on the 2 roads.
I hope this may have answered some of your questions.
A huge thanks to David – it really is fab not just seeing a layout like this, but also knowing how it came about.
Hope you enjoyed it as much as me.
That’s all for today folks.
Please do keep ’em coming, and don’t forget the Beginner’s Guide is here, if you want to stop dreaming, and start doing.
