Finishing the thru truss bridge at Gloconda

Last summer in the post First crossing of the Humboldt River I had started building a Central Valley Models thru truss bridge for the WP line and was scratch building a segmented concrete trestle for the SP line to match the bridges in this photo that I show again here as reference.




Completing the area around the river is a combination of several different projects including the two bridges that are all interrelated.  In this post I will cover the the finishing of the Western Pacific thru truss bridge which is in the foreground of the scene.

After assembling the Central Valley Model Works bridge,  the abutments that it would rest on were made from 1/4 inch plastic material and installed into the scenery on each side of the river.  They were then brush painted with Testors aged concrete.  One of those is shown in this photo.

I have always noticed that none of the bridge model kits include the bridge shoes that attach the ends of the bridge to the abutments.  I found a set on the KD Models Shapeways shop designed by Dwayne Ward who is modeling the Texas and Pacific in N Scale and has a blog for his T&P layout.



The bridge structure itself was then air brushed with Floquil Old Silver. After drying overnight it was given a wash of Testors black acrylic weathering wash.  The weathering wash really brings out the details such as rivets and the year of construction that is cut into the top plate on each end of the bridge.

I am now applying some weathering powers to highlight some areas of rust.

Here is the same abutment shown in the earlier photo after the same weathering wash had been applied.

Those bridge feet seemed understated until they also received the weathering wash when the bridge was done, now I think they really show off nicely.  I will be ordering more of these for my other bridges.



The ties were removed from the middle of a section of Micro Engineering flex track and the bridge ties that came with the kit were popped into place after ACC was applied to the rail bottoms.
This assembly will be air brushed a rail tie brown color and be ready when the time comes to install the bridge.

  1. Looks fab. I always like models that are weathered and your bridge is no exception. The Bridge feet look grouse.
