Andrew, it does look like that Din Rail. But on closer examination, it is 4 seperate 12" x 12" I-beams running the length of the bridge. I don't know for a fact, but it sure seems that this was once an entirely wooden trestle that was refurbished at some point, with the concrete bent toppers and the I-beams.
Well, here is a photo of the model bridge, all the various sizes of styrene to represent the lumber and concrete, plus some Evergreen I-beams. Also, a pile of nut-bolt-washer castings.
