Santa Fe style bridge Abutment
thingiverse
This is a three part print for a sloped bridge abutment in the style used by the Atchison, Topeka, and Santa Fe railroad. Design comes from a Santa Fe blueprint for "standard concrete abutments: general plans for various spans and fills." The sloped sides are appropriate for softer soil or larger fills. This model was done for Rick Fortin's Sierra Western and Santa Fe railroad. http://www.fortinweb.com/swsf/ I'd initially done the model with simulated board patterns (from concrete molds) but removed them because it was too coarse and complicated patching the seams Pocket for bridge was designed for a deck girder bridge (solid sides, tracks on top) 1 11/16" high with 7/16" horizontal space for bridge. Overall abutment is 4" tall with 45 degree wings. Abutment could be cut down for different spaces. SketchUp and STL files provided. The Santa Fe also used wings with different angles; the blueprints show 30 degree angles used. It should be possible to create a new left and right wing without changing the center portion. Printed on both a Form One resin printer and an AnyCubic Photon.
