O guage suspended layout 9

The 'red train' passes under the high line open girder bridge & behind the three span, curved girder bridge with concrete deck. Still need to create & install the left retaining wall. All bridge components were 3D printed: concrete retaining wall, concrete piers, girder bridge span, bridge bearings & concrete deck. Everything modeled full scale in Autodesk Inventor, derived @ 1:48 scale, 3D printed on a Creality Ender 3, assembled/glued, painted & weathered. O72 curved track. The open girder bridge that the train passed under was scratch built before I had a 3D printer.
