CN's M338 had some interesting, all EMD, power yesterday: CN 8862 (SD70M-2), CN 2434 (C40-8M), IC 6200 (repainted SD40-3). This photo was taken from the Fremont Ave. bridge in Dubuque, IA. The dense (at times) fog made for some beautiful rime ice on the trees at many locations. Oddly enough, this particular location didn't feature much of the frost.
