> Original model created in Blender 2.69. > Preview images rendered in Cycles render engine. > all images are render output. > UV unwrapped. 4 diffuse map 4096X4096 2 specular map 4096X4096 2 roughness map 4096X4096 > Shader setup included in .blend file only. > Detailed enough for close up renders. > All objects centered in the origin. > All objects and materials have significative names. > DXF file is tiangulated because of the conversion. > real world scale (meters) > the file you download contains 1 locomotive and 3 different kind of wagons. > policount refers only to the locomotive and the three different wagons contained in the file, not to the full train you see in preview images. You could have to relink the textures to the objects, but it should be easy because textures have the same name of the material they refer to.
