This is an N Scale 40 foot Hopper/Gondola Car Load.  I bought this as part of a Job Lot so I can't tell you too much about it and I'm not sure if it is wood chips or shredded scrap metal.  It is made of plastic and has very good detail.  They are about 4 inches long, 3/8 inch wide and is in very good condition.

I will gladly combine these small items to save on the shipping.
