I have built a couple arched steel bridges on a curve, my arches are underneath the roadbed. The one Dan is refering to will be a little more complicated, but what the heck, IT IS DAN, and Dan can do it. When Dan and I get together at these shows, our discussions go to some of the steel fabricating extremes. We are bouncing ideas back and forth all the time at the show. Thats what happens when you get two OLD steel fabricators together, that thinks alike. I am sure Dan will have the pictures soon of the finished project. Dennis

Hello fellas,
I see that we got your engineer brains going. I'm glad that most of you already realized that this is G Scale and the ceiling is the limit or sky whatever applies. It might not be realistic but it shouldn't be a big deal for grown men playing with trains right? The main thing is to have fun with this stuff.
As you figured ... something that I forgot to mention is that the outer track has a different elevation as it goes into the curve and then levels out on the straight sections.
Anyhow, how about some pictures of the progress.


We started by making the track base

Next in order to make the arches we welded upright braces to hold the curve of the arches in the right place

After that, the truss worked started. Horizontal and vertical pieces were placed, little by little to keep everything aligned.

Wow !!! Dan that is a work of Art!
However the pic looking lengthwise reminded me of The San Francisco Earthquake!

Another Great Job Done!

Wow Dan I bet the OLD head hurt figuring that one out,

Great job, What would be cool now is when that gets installed, take some real looking photos and convince people it is a full size bridge.

Again great job.
