OK. So we have established it is not a prototype. Now the is question is do we have any readers out there who has made one. MR Trestle & Bridge is showing a diagrahm of a double track bent system and even explains several methods. I am working in HO but I saw a model online in n for a double track.

Double track wooden trestles did exist. I don't even think you could classify them as rare. It was the high ones that were very uncommon. I'm sure if you checked through history you might find a high one where it was necessary.
I'm not HO scale but have plans for a 212 foot long by 42 foot high double wooden trestle. When I say plans I mean drawings
Right now I am building my 5th Bridge which is a 187 foot long by 66 feet high single wooden trestle....The double Trestle is my next bridge I am building.

That is some nice information Ed provided you. I wish I would have had that info when I was doing the research for my bridges
This is the old rough drawing I recorded my information on when I was gathering it for my double trestle. It is in prototypical feet and inches that can be easily converted on an HO scale.
The drawing is a bit consolidated so it's easy to find all the member sizes. I noticed some of the sizes of members varied a little bit from Railroad to Railroad. Being a carpenter my whole life I picked the varied dimensions that made the most sense to me.
Railroad Lumber was rough cut and was actual size in inches, unlike Lumberyard lumber these days that is a half inch thinner. I hope my rough draft helps
Thanks. You might want to checkout the publication MR Bridges & Trestles. It was a great help when I built the trestle on my home layout ( 120' long x 75' High. )
Harold,
I built a 50' double track HO trestle from scale wood this summer. If you'd still like to see another schematic, let me know and I'll send it along.

I basically have a plan to built it but I would ove to see the one you built. I always see new ideas.
Did you see this?

D&RGW and C&S are surely the narrow gage railroads with the most rolling stock available off-the-shelf. But there are others.
There were quite a few 3' gage logging railroads. If that's your pleasure.
There were also a number of "general purpose" 3' railroads.
My favorite is the Nevada County Narrow Gauge Railroad (yes, that's its real name). It ran from Nevada City CA to Colfax CA to connect with the transcontinental Central Pacific at Colfax CA. It was completed in 1876 and ran until 1942. You can easily get a feel for the countryside using satellite view. There was at least one spectacular bridge, across Bear River:

Thanks in advance
Hey i just designed 4", 6" and 8" double trestle that I plan to use on my railroad. It may not be exactly what's in the world today but after reviewing several they were built with whatever materials they had and what was going structurally work. I'm not a civil engineer but I think all the stress points are carried without over enginnering this.
