Although this is a road bridge over a river, it could have equally spanned over a railway line. It certainly has plenty of character and plenty of scope for those who like authentic weathering.
I have made a drawing for anyone interested in making a model for their layout. The jpg isn't that clear for showing the details but I can let people have the file in dxf or dwg format if they have access to CAD software. I could also print out onto paper to scale if anyone is interested. I have further pictures as well.
