The first and last hopper are Microtrains hoppers with different numbers.
The hopper in the middle is an Atlas hopper.
All hoppers have their original loads and of course this is N-scale.
I sure agree with Shamas about the loads. I worked in the Wyoming coal mines for twenty years. I thought they were kitbashed by you. My first layout was of the modern coal industry and I never could find hoppers with nice loads. I had to kitbash my own. Glad to see better ones are made now. Very nice picture also. Ron
