I have a beauiful wood trestle on my home layout. I belong to a modular club and I am planning to build a high wooden trestle for the club. The problem is that we have a double track. There is a plan in MR Bridge & Trestle which shows the bents for a double track. My question is. Does this trestle exist. I know it would not be practical in the real world but was it ever built?
This will prove useful, I think:

It shouldn't be this hard on a site that sells Internet products.

Thanks, Henry.
PITA that I can't make a link live that comes back to this site.
Anyway, thought I'd mention that the Yolo trestle they talk about is quite long, but only 20 feet high, or so. It's on a flood plain for the Sacramento River. And the reason it's a trestle, wood or not, is to allow a lot of room for the occasional high water to flow. And not wash out the bridge.
It really doesn't seem like anyone would make a HIGH double track timber trestle.
You should check out the Goat Canyon Trestle, San Diego County.
Although no longer in use, it is a twelve mile hike there and back to go see it. Many people do this because the live view of it in person is so magnificent.
It is the largest wooden Trestle ever built. 750 ft long and 200 feet high. From start to finish the Trestle almost turns a complete 90 degrees.
I have been doing a lot of research on wooden trestles as I am currently building one. I found any trestle built above 30 feet was built-in stories. This makes perfect sense since logs over 30 feet are a little scarce
I would very much like to answer your question of a double Trestle built high being practical or prevalent but I could only speculate.
I would think the reason they most likely we're not prevalent or commonly built is the extra cost and time to build would be considerable.
It seems to me a siding on either side of the bridge would be way more practical then building it double wide, even if the flow of traffic back and forth was somewhat moderate.
On the physics side of the equation, a double track bridge would always be more stable than a single track bridge, regardless of the height.
This is all I can say, not so successfully answering your question
It was a good question though
OK. So we have established it is not a prototype. Now is question is do we have any readers out there who has made one. As I said in the beginning MR Trestle & Bridge is showing a diagrahm of a double track bent system and even explains several methods. I am working iin HO but I saw a model online in n for a double track.
