They picked up all of the scrap rail laying about the yard and loaded it onto the flatbed. We're sorry to see them do this, because many of the scrap rails were laid between the yard and Front Street in an attempt to stop people from driving into the yard.
Smaller pieces of scrap went into the dump truck. Later (and not pictured), they used a smaller excavator with a hanging magnet attachment to pick up miscellaneous scrap metal.
By the time they left, the dump truck was filled to the rim with scrap metal, and that's probably a a good thing, since it's easy to recycle. I only hope this is not a precursor to Union Pacific putting up a fence and blocking our view of the railroad.
