So, one of my engineers was cleaning out his father-in-law's shop and found these copper nails:





He sent them to my team to see if anyone could figure out what they were for, and one of my other engineers, whose dad worked in the railyards in Tacoma, identified them as "Railroad Tie Nails".

Apparently they drove these nails into railroad ties to identify what year the tie was installed, so they would know when and which ones to pull up and replace. They were copper so that they wouldn't rust out.
