Prototype for Atlas HOscale bridges

[MStLfan]

For an upcoming modular project I bought a couple of Atlas bridges, their numbers 883 warren truss bridge and 884 deck bridge.
The module will be set in the southwest in the steam to diesel transition period.

However, I have not been able to come up with photos of these or bridges like these on the prototype. There are plenty of pictures, model and prototype, of girder bridges but nothing like these.

Were they used in the southwest or are they a design from elsewhere?
How were they used?
Any help is appreciated.
greetings,

I don't believe there's an exact prototype for any of there bridges,but they're a generic model of those type bridges. I believe they're not detailed enough underneath to be exact, both need more support beams and gussset plates, but with paint and light weathering they look just fine, if it looks like a bridge, it is. Both those styles were used all over, there was an article on bridges in either MR or RMC that showed , all of the bridges in a row on a railway some in the southwest. It had a truss then a deck and then a girder and then a trestle approach. Feel free to use them, I'm using some myself. Try using the bridges with some bridge rail and ties from walthers or micro engineering, the ties are closer spaced and will look better.

Kalmbach has a pretty good book (or "special issue"??) out now on bridges and trestles.
