Waiting for a warmer time of year are the piers and a diving board of the cottages lining the shore of Loon Lake, Washington, and on the cold morning of January 31, 2019, BNSF’s Chewelah Turn slowly traces the ice-covered edge of Loon Lake. The southbound train is powered by a set of A-B-B-B-B-A set of EMD locomotives—GP60M (rebuilt and now labeled a GP60M-3) No. 105 leading GP60B Nos. 337, 329, 344 and 338, and trailed by GP50 No. 3143.
