This is version 2 of a style of double track bridge used on the Florida East Coast Railroad.
Overall length = 257 ft. This actually represents an existing bridge at Turkey Creek near Palm Bay. Today one
set of rails has been removed but the deck plate girders and ties for the seond track are still there. This can
modeled by removing the text in the config file for track-2. The attachment points will still be in the mesh so
the rail only track can be replaced if you change your mind.
