This is not a great railfan photo. It shows two Ontario Northland engines switching along the Moose River. In the left part of the picture is part of a "tractor train" that is used on the winter road going north from Moosonee. Tractor trains have been the means by which large quantities of goods have been transported on temporary winter roads. The trains include various units for accommodation, merchandise as well as fuel tanks, all on skis and pulled by tractors or bulldozers. In recent years the quality of the winter roads has increased to the point where tractor trailers, pickup trucks and even cars can sometimes use them.
