The CP Winnipeg Beach subdivision runs from Winnipeg, MB north toward Gimli, MB. At one point the line reached to Riverton. This branch line was in danger of being abandoned. In August 2012 a portion of the subdivision north of Selkirk was purchased by the new Manitoba shortline, the Lake Line Railroad.
