Union Pacific train SONCH 18 pulls 40 cars of wind farm mast components through Dupo, IL on 6-22-2007. The train is headed to somewhere in Ontario. The pole line on the left is still active, sporting many Ohio Brass U-118s, U-180s, some MoPac U-152s, Hemingray 660s, and a lot of Hemingray 40s on the top arm. The train has just received a clear signal at North Dupo and is accelerating from a stop, hence the heavier exhaust.
