Some where I have original plans for some Campbell scale wood trestles...which I will look for...whenever I get the time and post here, unless someone can do it quicker. In the meantime, here is a link to scratch building wood trestles, how to go about building the deck, sizes of lumber and so forth. Its a PDF file.

Here's another link to Black Bear con. with a wealth of info about material for all kinds of Bridges/Trestles with plans. Do a little navagating on the list,click on drawings at top bar and then on the left You'll see different types to look at the plans. Great place to buy the materials from also, should You so desire.

Hello, does anyone know where I can get a pdf or digital file of an HO scale trestle deck that I can use as a template for a current trestle build?
