Milan Branch of the Iowa Interstate RR

The great bridge saga continues…

Today I received an update from my friend, Clark C., who is helping construct the two Rock River lattice truss bridges for the branch.

Clark is a true craftsman. And in the tradition of craftsmanship, he is testing the design approach to the bridges. Below are two images that show a “test bed” span. He is testing such things as lattice thicknesses, materials approach and heating the acrylic to help form it for alignment, etc. All this attention to detail is greatly appreciated and it will make for a spectacular presentation once completed.


Also: this last weekend I was at Trainfest in Milwaukee promoting the ProtoThrottle with Michael Petersen and Nathan Holmes. It was my first time at Trainfest and although it was rather grueling standing for almost eight hours both days, we all had a great time.

Nathan had graciously agreed to 3D print both bridge abutments and the one pier I needed. I plan to “skin” the three components with plaster and then distress, chip, and weather them to fit within the scene. Below is a rough setup showing the girder spans in approximate placement.

  1. Wow. those 3D printed bridge abutments are really great! Very cool solution.

  2. If I may, good sir, from long experience with trade shows: There are soft foam-rubber mats you can purchase, which do an amazing job of cushioning. We bought a few, and placed them where we knew we’d be standing most of the time at a given show.

    Hope this helps.

    The bridge is looking amazing!
