You may also want to do some weathering on ore cars. They were generally beat up pretty badly from the loads they carried and being loaded and unloaded.
There are many weathering suggestions on the internet. Google model railroad weathering or the like for ideas and supplies needed. Powdered chalks and diluted paint washes are good ways to go. Get some prototype in-service pictures to help you.
