The BNSF is working on replacing what's left of the ex-Santa Fe style signals east of Galesburg, so that was my focus back in early 2017. One unusual set I had forgotten about, was this pair at MP 168. The railroad put these signal right under Knox Road, so the signals are little dwarf searchlights since the overpass is above. I doubt they will be this way in the PTC era, but for now the Phoenix to Willow Spring Z-train blast by on main #2 heading for Chicago. I am guessing these are one and only? They are pretty cool, glad I got them today!!!!
