On a day looking more like early November than late February, an eastbound Santa Fe intermodal had to make an unscheduled stop at Wilbern, IL as SD40-2 5070, former Santa Fe, now an MKM leaser, had to be set out bad order with a hotbox. The crew made quick work of it, and with four EMDs still intact, had little trouble finishing the run into Corwith Yard in Chicago.
