A bogie (called a truck in North American English) is a chassis or framework that carries a wheel set, attached to a locomotive.

There are 2 versions for this model, as you can see in the images. 

Attached is a very worn and rusted Bogie. Secondly, a used, but less rusted version.

Both versions are in 1 local Blend file. You just need to change the scenes in the top right hand corner to get the one that you want. You'll seem them named appropriately.

This is a highpoly model. UVunwrapped, clean mesh and textured using Substance painter. It is completely destructive.
