This product is a high-detail HO (1:87) master STL of a compact industrial narrow-gauge shunting locomotive designed for HO narrow-gauge layouts, small industrial dioramas and display printing. The model reads as a generic workshop/quarry shunter: short wheelbase, low roofline, open cab window cutouts, external handrails, simplified rivet cues and stout buffer beams. Delivered as a single unified mesh combining body and underframe; it does not include separated parts, coupler pockets or motor cavities. The file is supplied locked to HO 1:87 — if you want to print at other scales scale the mesh in your slicer (1:160 N = 0.54×, 1:72 = 1.21×, 1:48 = 1.81×). Printing notes: for FDM, orient the model on its side or at a low angle and use supports for cab overhangs and exposed handrails. For resin printing, add supports under the chassis and roof eaves; thin handrails may need reinforcement during finishing. Intended uses: model railway sidings, quarry scenes, engine sheds, and weathering practice. This model originated from a legacy MeshRef export and is intentionally generic rather than a historical reproduction. Contact Miniature Reality for paid conversions (split parts, coupler pockets, motor-ready remaster).
