SCOTT KAY,
Thank you Scott. I had forgot MTH makes the 4650. I bought a CSX model when I was just starting in O Scale,that was a model of the 5161 though and I sold it. Think there was even a beige CSX model done many years ago.
Thank you much for the other info and links. Lionel has real nice hoppers,think they've got potash cars,also.
Thanks again.
Al
