diesel locomotive 3d model

Highly accurate industrial diesel locomotive (ÖBB 2070 / RK900 style). STRICT engineering model, no stylization. Separated parts: - main body (static) - chassis (static) - two bogies (rotating via vertical pivot) - wheels (each wheel separate object) - coupling (separate) Movement: - each wheel rotates on its own axis - wheels not merged with bogies - bogies rotate independently from chassis - clear pivot connection Geometry: clean hard surface, sharp edges, symmetrical, correct proportions (low hood, offset cabin, flat roof) 3D print ready: watertight meshes, no holes, no merged parts Output: clean topology, animation-ready, fully separated mechanical structure
