Here is a link to the latest version of the plans I created for my model of the Rock Creek Trestle. I spent tens of hours over a few days refining the last version. This new version was carefully corrected (there were many small errors) and updated to include a new girder height and lots more hardware and correct lumber sizes. I also developed a side view, which took tremendous effort, as the photos just do not exist.
Remember that these are not perfect; since there is so little information available about the trestle in the era I am interested in (early 1940s) I had to use educated guesses and the few reference photos and drawings I have to make the best attempt. The plans were drawn in Adobe Illustrator. Each of the first 20 pages is a separate bent. The last few pages show a side view. I am gearing up to begin building the model and will share my progress as it is made. Comments and questions are welcome!
EDIT May 22, 2020: I have updated the plans once more: File is now available on Dropbox.
