Bethungra Loop in "N" scale - pt 5

Part 5 - A sea of foam.

Another Bevan Wall video image of the 1997 LVR tour train passing through the cutting between the two tunnels on the Bethungra Loop.  Bevan Wall has made numerous videos of NSW railway action over the last 3 decades, and his DVDs are well worth purchasing (dare I say as a xmas present?).  This image is a screen capture from you-tube

Since my last post, circumstances have conspired to limit the amount of time I can spend on the Bethungra Loop layout.  I won't elaborate here as to the cause, but things are now improving, and may be back to normal sometime in January.

The rear tunnel portal will be impossible to view once the backscene is installed.  The foam "rockwork" above the tunnel is removable for access.

Looking back towards the hill.

Getting down the foam is like a 3 dimensional jigsaw, where all the pieces have to be cut to fit.  Fortunately, some of the foam sizes were at the correct thickness for the largely flat paddock that is between the road, and the railway.

Another view of the paddock, and foam rockwork, after a rudimentary smoothing with coarse sandpaper.  

After sandpaper smoothing.  The section between the two tunnels is nowhere as deep as the prototype, but the lack of depth was a compromise with keeping the grades of the model under 3%.  The three sections of foam visible above the trackwork are all removable

The thickness of the foam can be gauged by this picture.

As I am not a fan of white polystyrene foam, I am pleased to advise that this phase of the layout build is behind me.

I am doing some preparation work for the next phases of the build.  To correct my poor colour choice for the grass in the previous blog post, I have ordered some Woodland Scenics fine ground foam colours (Blended Turf, and Yellow Grass), which I hope will be arriving in my mailbox soon.  I also sourced some large sheets of 3mm MDF for the backscene, and have taken a couple of pictures of the upper loop, to aid with painting

Taken from the Olympic Way road, looking towards the railway.  The "flat" paddock is quite a feature, as is the line of trees hiding the railway.  Of note is the heavy tree cover on the hills

In the meantime, whenever I get a spare 30 minutes or so, I will be mixing up the Sculpt-it "plaster" and applying to the areas of foam that either need gaps filled, or cuttings/rockwork done.

Until next time
