DWP 5850 and mate handle heavy switching at DWP's West Duluth yard on the hillside above Lake Superior. The former GTW Geeps are now lettered in DWP and in an era of rapid change, the whole operation will leave Minnesota and move into a new yard at Pokegama, WI, south of Superior. The new yard is adjacent to DMIR's Interstate Branch and will eventually become an integral part of CN's mainline from western Canada to Chicago.
