curved railroad track 3d model

Industrial mining cart rail track 90 degree curved corner section. Two parallel steel rails curving smoothly through a quarter-circle from one end to the other, mounted on wooden cross-tie sleepers radiating outward like spokes from the curve's center, ties extend beyond the rails. Same gauge spacing as straight sections, designed to connect seamlessly at both ends. Rails flat-topped rectangular profile, ties dark weathered timber. Loose gravel and dirt between ties. Heavily aged, deep red-orange rust, cracked weathered wood, dust, dirt, decades of use, no clean surfaces. Modular 90 degree curve to connect with straight sections. Rugged 1900s industrial mining aesthetic, game-ready PBR low-poly, neutral pose, clean silhouette
