A pair of Union Pacific EMD SD50s power a southbound taconite ore train over the at North Escanaba, Michigan, on a cold January 18, 1997. This Pratt through truss bridge was built in 1892 by Lassig Bridge & Iron Works for Chicago & North Western on their ore line running from Partridge Junction to the ore dock located on Lake Michigan at Escanaba. After Union Pacific merged Chicago & North Western, it only had the ore line for a short time before Wisconsin Central, and later Canadian National, operated it. Unfortunately, this bridge was replaced in 2015, and with the closure of Empire Mine, Canadian National closed the ore dock in Escanaba in 2017.
