I thought I’d posted pix from this wye up in Rift WVA at 37.281159, -81.665041.  There are three trestles here: a through truss, a pony truss and a pony plate.  All take the line over the Clinch River.  The first picture is the through truss and the second shows the humor of the rail guys.  It’s hard to read the far junction sign, but it reads “‘Omega”.
