All of the coal hoppers currently on the layout are Micro-Trains 2-bay 33' hoppers, lettered for Clinchfield railroad (in an homage to the Model Railroader project, more than anything else).  While different hoppers might find there way onto the layout, it will basically be in a through train. 
 
There are only two car numbers in the ten hoppers currently on the roster, so I will renumber them when I detail them.  I will also add a few separate grab irons, and look to distressing them slightly to show some use.
