The Tree Hut Branch line. Part 2 of ∞ "Boulder Creek Bridge"

The next hurdle is a bridge across "Boulder Creek". I had played with the idea of making a brick arch bridge but went with a simple timber affair to save time. Today I managed to plan out where the piers are to be, dig a few holes and cement them into place. I had a few bags of river stones laying around and excess concrete so figured I would layer the concrete like icing everywhere and then layer on the river stones. The main reason being when it rains the modest stream turns into a raging torrent and would no doubt wash everything away. This bit reminded me of building my nz120 layout although somewhat scaled up but quite satisfying.

How it looked before

Piers & river stones in place, waiting for things to cure

Looking North

Cleaned up, needs more rocks

Piers cut to the right height, the line is completely level from the flame tree 

Its largely a level run up to the bridge, I need to cut into the top ahead and redistribute the clay.


Given the distance to the build site growing further away from the shed the wagons have really been useful to cart materials and tools back and forth. A few pictures of various loads. Need to find a big log and cart it on the log wagon behind the climax. Once the railway gets past the big bridge I can see the railway being used to cart logs up to the mill.


Bridge progress after day two

More Piers firming up.

Day three bridge fixed in place, still to add pedestrian walkway alond the side and more boards & plastic, then to be backfilled with some clay.

From above, track ready to upgrade its sleepers

Day four sees track fixed in place with new sleepers



After some heavy rain overnight the waters flowing nicely with only a hand full of rocks swept downstream.

The next step, a bit of an embankment.

Work continues on the embankment, Da delivers another load of timber

Looking forward, the cutting starting to take shape.

In the process of removing problematic slanted pines before the railway gets built, should clear up the view a bit

The Tree Hut Branch line. Part 3 of ∞ " Paina Junction"

Now that I've built a bridge and got over it I find myself at Paina Junction, surrounded by tall pine trees. Today I borrowed a log sitt...
