An overview of the CN yard at Proctor, MN looking northeast. The car shop is at the bottom and the yard office/tower is on the opposite side directly above. The roundhouse, diesel shop and turntable are in the upper left. The roundhouse and turntable are the last active ones in the Twin Ports. In what used to be strictly an ore sorting and staging yard in the days of the former Missabe, CN has turned this yard into much more with additions, removal and rearranging of trackage and a lot of sorting and switching of commercial traffic taking some pressure of their yard at Pokegama, WI.
