I don't know what to call this to search for more pictures. My wife (and puppy) and I were in Jefferson City, MO for the weekend to take pictures of their capital building. Between the capital and the river is a small UP rail yard.
I didn't take the time to get a good picture, but you can sort of see it here. Rather long green cars with lengths of rail on roller-racks and a few hoppers with ballast. I'd like more / better pictures if anyone has some, or at least a more technical name for these highly customized cars. Also, does anyone make a kit model of them? Might be a fun addition to a larger layout.
