This compact narrow-gauge industrial locomotive is modeled from a late-20th-century works engine and is supplied as a single master STL at 1:87 (HO). The model preserves the rectangular cab opening, side perforated access panels (regular circular grid), exposed running wheels with connecting rods, and a lower sill with visible bolt clusters—features that give realistic weathering targets for paintwork. The cab interior is open so you can add an HO-scale figure or glazing. Print notes: for best results print at 0.15–0.20 mm layer height with 3 perimeters; consider orientation with the underside flat to reduce supports. Because the perforated panels retain real-world hole pitch, small-bore printers may need thicker perimeters or slight upscaling. Ideal uses include HO model railroad layouts, industrial dioramas, and wargame terrain. Included: one 1:87 STL. To print at other scales uniformly scale the file in your slicer and verify thin feature robustness before printing.

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