Oba is the site of the crossing of the Canadian National (originally Canadian Northern) Railway’s transcontinental main line and a major interchange point for traffic heading off the Algoma Central Railway. Both eastbound and westbound traffic is transferred here; primarily steel products from Sault Ste. Marie but also westbound traffic via Hearst from CN and Ontario Northland in northern Ontario and Quebec is handled via Oba.
While CN now owns both lines and has in recent years altered some of the trackage here to eliminate the diamond and extend a switching lead, to this day Oba remains an important transfer point between East-West and North-South routes.
