The NF110 is a diesel-electric locomotive built by General Motors Diesel for narrow gauge service with the Canadian National Railways in Newfoundland (see: Newfoundland Railway). Only nine examples were built between 1952 and 1953, although thirty-eight identical NF210s were later built. The last examples were retired in 1986 and afterwards three examples were preserved in non-operating condition, all located in Newfoundland.
