Trackside infrastructure pack for 1435 mm railways: 25 m catenary spans (mast, cantilever, contact wire, messenger wire, droppers) for single track on either side and a two-track portal, three-aspect colour-light signals (red, yellow and green lit), a dwarf signal, speed board, milepost, point machine, relay cabin with a separate hinged door and a trackside fence module. Every object is one clean welded solid.

Highlights

• Catenary: 25 m spans with mast, cantilever, insulator, registration rod, contact wire (5.50 m), messenger wire and droppers
• Two-track portal with lattice cross beam
• Three-aspect colour-light signals with ladder, back screen and hoods - red, yellow and green variants
• Dwarf signal, speed board, milepost, point machine
• Relay cabin with louvres, cable duct and a hinged steel door
• Trackside fence module (3 m)
• Armature INF_Rig (2 bones): Root + Cabin_Door. Baked action Door_Open_Close, Rest.

Technical details

• 21,032 polygons (21,032 triangles + 0 quads, no n-gons) = 21,032 triangles, 10,044 vertices, 15 welded shells
• Mesh checked with exact triangle tests: 0 self-intersections, 0 z-fighting, 0 non-manifold edges, 0 degenerate triangles
• 1 non-overlapping UV atlas inside 0-1 (worst overlap 0.00% of covered texels)
• 4096 x 4096 PNG maps: Base Color, Roughness, Metallic, Clear-coat, Normal (OpenGL), AO and packed ORM
• Formats: BLEND (Blender 5.x scene), FBX, glTF 2.0 GLB, OBJ + MTL, USD / USDZ - plus a RIGGED set (FBX + GLB + BLEND with the armature and baked actions)
• Two texture looks: the weathered set (default) and a separate CLEAN variant (new, unweathered paint) - same UV layout, own FBX / GLB / BLEND and 4096 px maps
• Real-world scale, 1 unit = 1 m, Z up, rail head at z = 0 (1435 mm gauge). Original design, fictional names and lettering, no real railway brand or logo

Good to know

• The mesh is a mix of triangles and quads (no n-gons) produced by exact boolean welding, so some sliver triangles exist. Shading, UVs and silhouette are clean; it is a render / game-ready mesh, not clean quad-flow topology for subdivision or deformation.
• Real-world scale, 1 unit = 1 m, Z up, rail head at z = 0, 1435 mm gauge. Lettering and numbers are fictional; no real brand or logo.
• Tested in Blender 5.2 (Cycles). FBX / glTF / OBJ / USD were exported from the same scene; not individually tested in Unreal / Unity.
• Signal lenses are separate materials (On = emissive, Off = dark); swap materials to change the aspect.
• Catenary wires are thin real-scale solids (contact wire 28 mm); keep this in mind for very distant LODs.
• Blender's FBX / glTF importers guess bone length from child bones, so a few parent bones may look very long after import (display only; set Armature > Viewport Display > Shape to Stick).
