Hi

I am looking to replace my 36’ Athern coal hopper wheel sets with Kadee non magnetic ones but dont know which type to buy. Two are avaiable #520 or #521. Can anyone help?

Thanks John

The hoppers of that era when 36’ was common had the rib back wheels The 521 version there. Some might have had the 523 version which is 33 inch. But you should be fine with the 521
