I easily adapted this Unitrack truss bridge to fit with my Peco code 50 flextrack. I also purchased two additional bridges which did not take much work to shorten to 105 scale feet for a shorter span than the original 150 scale fee. This bridge comes in red and green as well as gray, but I've never seen a truss bridge that was painted last week so you should weather it from its shiny plastic. NOTE: make sure you have strait approaches to both ends of the bridge or the train will hit the truss on the curve.
