In 1928 the provincial government grouped the ED&BC, CCR, AG&W, and PVR under the collective name Northern Alberta Railways (NAR), which received a federal charter on March 1929.
NAR's locomotive fleet was completely dieselized by October 1960 with EMD GP9's 201-210 (208 was wrecked, rebuilt and renumbered 211 in 1972.), and GMD GMD1's 301-305.
