The low light towards the end of a winter's day bathes this U717 from United Taconite as their hot taconite pellets move south for the yard at Proctor, MN.
Rolling south along the CN Missabe sub as the sun sets. That plume on the horizon is the U.S. Steel Minntac plant where this train originated about an hour or so previous.
That low winter light looks good plastered on the side of this all EMD power set and ore cars complete with a little bit of steam rising as the cold air mingles with the fresh taconite pellets.
