hon30critter Really nice bridge Graf, but I think you have one thing wrong: Graffen Painting all the metal parts and drilling holes for 600+ NBWs is a bit of therapy. That is not therapy! After doing that is when you need therapy! Start with a shoulder massage, and then maybe move on to an Opthamologist to get your eyes straight again! Dave

Ah, shucks... That's why I have a wonky eye.
The backrub is sorted out though. SWMBO is quite handy.

I'm just a dude with a bad back having a lot of fun with model trains, and finally building a layout!
hardcoalcase Nice work! I picked one up at a swap meet a few years back to use on my circa 1910 anthracite road. For now, its still "sticks-in-the-box" waiting for layout construction to catch up. But I do have one question... prototypically speaking - would such a small bridge be able to handle 30-40 ton hopper-gons and medium sized consolidations? If not, I'll build it for horse and buggy traffic. Jim

Scaling off the photo, I get a clearance of about 9 1/4 feet. That's too narrow if you're doing standard gage.
In my opinion.
Looking at the Wikipedia photo, it does look like a nice lightweight road bridge, though. Single lane, of course.

SS Ltd claims that the inspiration was a narrow gauge bridge over Dinky Creek in California. There is a similar bridge of this type there but it was a highway bridge built in 1938: https://upload.wikimedia.org/wikipedia/commons/b/b3/Dinkey_Creek_Bridge.jpg from https://en.wikipedia.org/wiki/Dinkey_Creek_Bridge
For loads as you describe I would change the bottom chord. For higher loads I would avoid the many splices in the tensile member and use longer timbers with fewer splices like in a Howe truss bridge.
The arched top chord needs these splices for the shape anyway. Pressure joints are easier as one can make them form-fitting the contact load transfer.Regards, Volker
WOW! I really like it.

Talk about a little model with tons of character. Very nice build.

Living the dream.
Recent build.
Sorry, no construction images. My memory card did not want to find them....
