Rich Holzapfel's work train pulling fines out of 223 pit (8/22/98). Fines
are a byproduct of making ballast. They are the leftover small particles
that you would call sand or D1. The ARRC uses them to build shoulders where
the roadbed needs to be solidified. We dump the fines out of the air dump
cars and then spread them level with the Jordan spreader #8.
