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 perfect for softer soil or larger fills. This model was designed specifically for Rick Fortin's Sierra Western and Santa Fe railroad. Check out the details at http://www.fortinweb.com/swsf/ Initially, I built the model with simulated board patterns (from concrete molds) but removed them because it looked too coarse and complicated to patch the seams. A pocket for the bridge was designed for a deck girder bridge (solid sides, tracks on top) 1 11/16" high with 7/16" horizontal space for the bridge. The overall abutment is 4" tall with 45 degree wings. You can easily cut down the abutment for different spaces. SketchUp and STL files are 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 successfully on both a Form One resin printer and an AnyCubic Photon.
