Beavers caused this! On a fateful night in September 1993, Algoma Central’s ore train with SD40 184 and GP7 102 was descending a heavy grade when it discovered the right of way just ahead washed away. Investigation determined a beaver dam over a mile away and higher in the mountains contained a large body of water and following recent downpours the dam suddenly gave way that night. The crewmen survived and recovered. Photo at AC shops at Steelton, Ont. Sept. 29, 1993.
