Sometimes O.W.L.S. Are Not What They Seem-Davis Junction IL
A Twin Peaks TV show reference to owls in the caption for fellow fans.
"One-Way Low-Speed diamond frogs are used in their namesake diamonds, often referred to as OWLS diamonds. These types of frogs are analogous to jump frogs in turnouts: the higher-trafficked line crosses the diamond on a normal rail surface in tread-bearing mode, and the lower-trafficked line crosses over the higher-trafficked line in flange-bearing mode."

This diamond is where the CP mainline crosses the recently reopened Illinois Railway line from Rockford south to Flagg Center. IR in 2019 filed to abandon it from south of DJ to FC but apparently had second thoughts.
