The BNSF is working on replacing what's left of the ex-Santa Fe style signals east of Galesburg. Here the Stockton, CA, to Willow Springs, IL, Z-train blast by MP 171 and a pair of classic ex-Santa Fe style searchlight signals that are on their way out. Lots of orange markings on the ground here, so it wont be long! This is the 1st set east of the crossovers at Yost in East Galesburg.
