CFMG 6910 was an SD40, formerly CN 5077 (class GF-30e). It was built in 1969, and saw service on UP and CSX lines in the late 1990s until it was retired from CN on January 8, 1999. It was rebuilt by Alstom by the spring of 1999 for CFMG.
6910 belonged to the CFMG (Chemin de Fer de Matapedia et Golf) but was often seen on the NBEC.
Both the NBEC and CFMG were owned by the Quebec Railway Corporation.
