A hand-cranked WORKING model of a railway swing bridge in N scale 1:160 (36 m through-truss span in the real world). Turn the crank: a 12-tooth pinion drives a ring gear and the span swings 90 degrees on its drum pier to open the channel. Four end locks (sliding bolts, each with its own lever) hold the bridge closed or open. This is the free single-scale N 1:160 set: 18 STL files, no supports (PrusaSlicer-checked, 0.4 mm nozzle, 0.2 mm layers), about 212 g. Designed and slice-checked, NOT test-printed yet - renders, not photos. The ship and trains in the pictures are render props and are not included. The full kit with H0 1:87 + N 1:160, multicolour 3MF files and the extra instructions is on Cults3D: https://cults3d.com/en/3d-model/game/working-railway-swing-bridge-model-hand-crank-end-locks-h0-1-87-n-1-160 . Part of a series of working hand-cranked port and railway models. Made with AI assistance (parametric design in Blender).
