Continuing north on Highway 61 on May 7, I spotted the tail end of this train from the highway near Wabasha, MN. Pulling off the highway and discovered the Soo Line (ex-Milwaukee Road) GP38-2 4515 and sister 4451 pulled into the siding to await the passing of another train, as I recall that day it was the late-running eastbound Amtrak Empire Builder from Seattle and Portland.
