Soo Line locomotives

Included in this list of Soo Line locomotives are those of the Minneapolis, St. Paul and Sault Ste. Marie Railroad, as well as those of the Wisconsin Central Railway, which it inherited on its lease in 1909. The M.St.P.&S.Ste.M. finally merged the WC and the Duluth, South Shore and Atlantic Railway on December 30, 1961 to form the Soo Line Railroad. The Soo Line later acquired the Milwaukee Road and became part of the Canadian Pacific Railway.

Note that WC locomotives are shown as after they were re-numbered and reclassified into the Soo Line scheme, with WC locomotives having numbers 2000 higher and classes 20 higher than their M.St.P.&S.Ste.M. counterparts.
