I was mistaken about the bridge. It is made by Faller, but it is a steel arch bridge with trusses in the ends. I did notice in the Walther's catalog that they offer a single track truss bridge in the cornerstone series that might work. It is listed at about $25, and you would need 4 of them. If you want an exact replica, you would need to scratch build the bridge. I don't know of a commercial offering with the gentle arch accross the top like the prototype. If you are not that fussy about being exact, you could kitbash two Atlas Warren Truss bridges for each one of those 4 bridges and get something that would be a nice stand in. If you kitbash two Atlas bridges to make one, I would use a couple of pieces of square brass tubing underneath to strengthen the joint. I noticed at my local hobby shop that 1/8 inch brass tubing comes two to a package. They look to be about the right length. If they were fastened to the bottom of the two Atlas bridges with epoxy and painted black to match the bridge, it would make a strong, good looking inexpensive bridge.
