Prompt
Create a realistic HO scale (1:87) single-track railway tunnel portal with matching left and right retaining walls for a model railroad diorama. Inspired by European and Turkish mountain railways (1950–1990). Heavy stone masonry arch, visible stone blocks, keystone detail, thick side pillars, realistic civil engineering design. Weathered natural stone texture with subtle dirt, moss, water stains, and erosion. Retaining walls built from matching stonework and suitable for hillside terrain. Separate printable parts: tunnel portal, left wall, right wall. Flat rear surfaces for easy installation into foam or plaster scenery. Optimized for FDM 3D printing: watertight manifold mesh, no floating parts, no thin fragile details, minimum 2 mm wall thickness, minimal supports, durable geometry. Tunnel opening sized correctly for HO scale trains. Professional model railroad scenery quality.
