Wooden Truss Bridges

[DR. Anatomy]

Does anyone know a good web sites dealing with "How to construct wooden truss bridges from scratch?"

[Semper Vaporo]

You have posted in "Steam and Preservation"... are you building a new bridge to preserve a rail line?

Google the terms you have quoted and you will find several web sites that describe all sorts of bridges, I am sure many of them include considerations and calculations for how to build a truss bridge from wood and what is necessary for support.

Well I sure hope you're a modeller.  If you're asking how to build a wooden truss bridge for a real railroad, you shouldn't be building one.

I am sure we are dealing with a modeling question, and I'll move the thread appropriately.

If I may, a truss bridge is probably not the correct term.  If you mean an old-fashioned timber bridge, you would mean a trestle.

I found this site quite useful:

It is after the prototype or the Rio Grande Southern Railroad, but no reason why it can't be adapted to your needs.

However, if I am wrong, and you know that you definitely want a truss bridge, try this one:

That's mine. I've built this trus-rod bridge for narrow gauge module. You see the step by step pics.

Hope this helps.

How large of a bridge are you talking?

Scenic express has bents, decking etc that lets you build some great bridges.  You could also buy a couple of them and scratch wood and make your own by copying the basic form.

I have replied to your "truss" bridge" question twice with links. I have linked to kits {which can give you the knowledge to build one on your own} and to site on how to build TRUSS bridges.

If you relly do mean a TRESTLE bridge {like Crandell has surmised} here again are some inks to TRESTLE bridges to help out:

I am not sure what you are looking for and any info I given here, is available to you over google too:

Kalmbach {our parent} used to have a book on building them. GO to the "shop" link at the above right top to see what tehy offer now or watch Ebay for the older books. Here:

Good Links.  Never saw that first one but it's not on my favorites

Thank you for the info. I am trying to build a wood truss bridge that will spand a small river.
