Thanks luke.There are composite metals that are used in all kinds of applications.I forgot about wood and metal as in bridges.

Dana is correct. When trusses are referred to as "combination" or "composite", they're referring to the mixed use of timber and metal parts.

I have a question.I see the word composite used in the pictures of this bridge.I've dealt with composite metals in the past.Is this bridge made out of composite materials?From what I remember composite metals are more than one metal.

It seems like this railroad built multiple wooden truss bridges- there is another that is abandoned farther down the line. Who knows, there may have been even more than these two! https://bridgehunter.com/va/cumberland/cartersville/

Is this a rare wooden railroad truss? It certainly seems to to me!
