I had previously made up some small styrene fencing brackets that I attached to the top of the fence posts, and as the bottom of the gates have a long pivot that is buried into the ground below the gate, the top of the gate goes up through these small brackets which attach to the fence posts next to the gate and the fence posts are allowed to pivot, open and close as the mood allows. So this is how I have working gates on my layout at various locations.
This is the Murwillumbah Cement Silo from the layout aisle side before the fence strainers had been installed. It is very similar to the one the Southern are bringing out. I still have more work to do to the grounds inside the fences.
This is the railway side of the cement Silo. I have a few small detail items to add to the front of the structure. And yes, the roller doors at each end both work. I think I had a door for the adjacent shed, but do you think I can find it?
