In September of 2011, Mobil Grain acquired this 402 kilometer rail-line running southwest of Saskatoon.

CN running rights from Davidson northwest to Saskatoon, and Saskatoon southwest to Delisle, connect BGS with it's affiliated and preceding shortline, Last Mountain Railway (see map for details). Big Sky Rail provides producers with a competitive freight alternative and ensures that the railroad stays active and available for Saskatchewan's vast delivery needs.
