As this is the first significant landscaping job I've done on a model railway since I was a kid, I'm surprised about just how forgiving it is. If the colour is wrong, you can go over it, sand it back, repaint it, whatever; but nearly any mistake can be rectified.
For best effect, landscaping progresses in layers and stages. Using a several excellent references and a number of materials, the photos show where I've got to. No area is finished yet, but you can see that some areas are close.
Two significant additions are the static grass applicator, which I made for under $35 following the instructions at http://csxdixieline.blogspot.com/2010/06/howto-static-grass-applicator.html I tried it out today and it worked a treat. This is surprising, because rarely do I find that something I have wired up first-go works. In this photo, the area in the foreground has been landscaped with static grass.
Secondly, I scratchbuilt a rail-rack and gang shed. Again, there are some excellent references available to help the modeller obtain an accurate and authentic result. I recommend Branchline Modeller 1, and in particular Jim Longworth's article "A Desktop History of Gang Sheds in NSW" in ARHS Bulletin, May 1999, pp172ff.
