CNW 5062 brings a westbound under the Hwy 30 bridge near Westside, IA in May of 1987. This train was a little underpowered as they had a hard time maintaining 40 mph for most of their trip.
UP's influence on the CNW is becoming more common as seen here. GP50 5062 heads two UP SD40-2's on the west bound as it approaches the US 30 bridge east of DeWitt, Iowa.
