Randy,
The old pin connected Q Plattsmouth bridge was drawn for the April 1964 issue of model railroader. Harold Russell did an article with photos and drawings of a pin connected truss bridge in the April 1998 issue of Model Railroader. While the bridge I’m building isn’t straight across the top like Russell’s drawings, the other details were helpful in designing my bridge to match the photos.

Subject: RE: [CBQ] Truss bridge diagram?
Thank you for the reply, Nelson. I'll be modeling just pre-WWII. But I'm also writing a report on the bridge as part of my documenting the Ashland-Schuyler branch line, and I'm just looking for a typical Q truss bridge diagram so I can format my upcoming drawing accordingly--style of drawing, linestyles used, type and amount of information (angles, tiebars, lacing, floorbeams, etc) included, etc.
Bridge 0.91 was a 132-foot, six-panel Pratt truss and based on my measurements of "sister" bridge 66.66 over the Republican River, was 25 feet even truss height. It's interesting that the bridge was pin-connected end-to-end, with the expansion end suspended from swing hangers rather than riding on shoes.
