Screw dowels (trenails) on the Santa Fe
This article is about trenails, also called screw dowels. These are described in the 1904 Proceedings of the American Railway Engineering & Maintenance-of-Way Association:
"Attention has been called to a method developed abroad, whereby the wear under the rail or at the spike in a soft wood tie
can be materially decreased. This consists of the insertion of a hardwood trenail, so-called, being a wood screw of two or
three inches diameter, having a spike hole bored in the center. This trenail is screwed into a hole tapped in the tie, and a spike
driven or screwed into it..."
