Before I adhere the track to my new micro layout, I want to weather the two small viaducts I have as part of the track plan. Any recommendations on the best method to do this?

These are through girder bridges. A viaduct is suspended roadbed held at grade by a masonry and/or stone arch structure. The girders would be painted black, and over time the fillets, flanges, and rivets would develop rusted sections and streaks below them. The bottom flange would be dirty and heavily rusted.

Ahh okay. I was just going with what it said on the Kato package (2 7/16” straight viaduct).

Good reference pic! Any recommendations for weathering supplies? I was planning on using just black spray paint and weathering with acrylic paints to simulate the rust.

I used Floquil 'rust' on rails, but that brand is gone. For any tinting, painting, and weathering, I just fudge something passable out of the Plaid Craft acrylic paints available cheaply at Wally's. A single drop of red, half a drop of yellow, and maybe some Burnt Umber, just a half smidge, and dilute that in about 1 tbsp of water. Then, with a barely wet small brush, and a steady hand, start swiping the sides of the braces and the edges of the flanges. Don't overdo it, let each coat dry thoroughly, and then re-apply if it's too thin.

I’ll give it a shot, thanks!
