WSOR train ML leaves Plymouth on its return trip to North Milwaukee. This job ventures onto the Superior Subdivision as needed no more than twice a week (Tuesdays and Thursdays), though usual practice has lately been a run up every other week or so. This portion of the line was put up for abandonment by Canadian National in 2004; the State of Wisconsin purchased it and designated WSOR the operator, with the first move being in January 2005. With so few trains, it's not difficult to understand the rusty look of the rails.
