Looking for some model and rigging help on a project with steam engines and rolling stock

Hey people! this particular period and part of the world is Japanese National Railway’s, its a group project where trying to get going, we have blueprint’s and reference color pictures if possible of the engine’s, but some engine’s are hard to find photo’s off, so where using their model counter part of them to give the said modeler an idea how they should look. including with passenger car’s or similar. also help with cleaning up model’s from a different program platform.

Note: we do have one on the team, but he has been really busy with his life, dont wanna push him to much.with our project.
