Railroad Companies in Louisiana in the late 70s?

Yes, N Scale does lack a lot of road names..

In your case I think I would just use the L&N Alcos since they was still plentiful on the L&N in the 70s..In fact a L&N RS3 worked out of Maysville, Ky until being replaced by a GP9 around 78.

I own at least three locos of each Railroad mentioned in my first post.
So I cover quite a lot and variety is guaranteed.

My main interest is the Rock Island, followed by the Illinois Central Gulf.
