This is the view under the model bridge; pretty much as it was in the first half of the 1960s including, sleepers laid against the wall, the single rail buried in the grass, the fences, the trees on the far side of the embankment and the tree line in the backscene.
The field fence was particularly troublesome to install, mainly due to the bridge and embankment hindering access.
The fence is an unusual design. Unusual because I could not find any other examples of the post on the web. The post comprises T section metal posts with sloping sides supporting five wire runs. Wire stays fit between the posts.
The posts were installed first and then bare electrical copper wires fed through them followed by fitting of the stays. The fifth wire at the base was not installed as it would have been buried in the long grass! I roughly painted the parts a rust colour.
All, except the wires, were resin 3D printed by myself. They are small, thin and with the holes make them fragile. Several broke during installation but, thankfully, I had just enough spares to replace the damaged ones.
My CAD design is shown below.
