Bring early 1900s industrial character to your layout or display with this steam traction engine model, delivered as a single 1:87 (HO) master STL. The model preserves the defining features of a road locomotive: a horizontal riveted boiler with visible seam rivets, a vertical smokestack forward of the boiler, a large spoked rear drive wheel with rim-mounted traction cleats, a smaller spoked steering wheel at the front, exposed side gearing and a canopy-covered operator platform. What’s included: one watertight 1:87 STL with named sub-meshes for wheels, boiler, gears and canopy supports. Printing tips: orient the model on its side or on the frame rails to reduce bridging; use 0.12–0.20 mm layer height for FDM; resin prints yield the cleanest rivet and spoke detail. The listing includes a short guide to scale conversion (how to resize the 1:87 file for 1:72, 1:48 or 1:160). Suitable uses: HO model railroads, period dioramas, museum display models and tabletop scenery. Note: smallest internal fittings were simplified where the photograph lacked clarity.

Available railroad scales: Z (1:220), N (1:160), HO (1:87.1), S (1:64), O (1:48)
