Canadian National Railway class O-8 was a class of 0-6-0T steam locomotives. Forty-four tank locomotives were built by the Grand Trunk Railway (GT) in their Point St. Charles shops from 1884 through 1895. Most were built with round-topped saddle-tanks and classified as F4 by GT and later O-8-a by CN but the eight built in 1887 had rectangular side tanks and were designated as class F3 by GT and O-8-b by CN.
