Canadian National #7470 is an 0-6-0 (Switcher) type steam locomotive that currently works on the Conway Scenic Railroad in North Conway, New Hampshire.
7470 was built by the Grand Trunk Railway Point St. Charles Shops at Montreal, Quebec in 1921. The Grand Trunk classified the switcher as F9 Class and numbered it as Grand Trunk Railway #1795. It soon became and renumbered as Canadian National #7470 when the Canadian National Railway absorbed the Grand Trunk in 1923, they reclassified it as a Class 0-18-a.
After it's retirement from service in 1960, 7470 was originally spared scrapping, until it was saved by being sold to the Canada Dominion Sugar, where it spent some additional years as a switcher. Later, in 1964, it was purchased by the Ontario government for a transportation museum in Canada, but that never came to fruition.
7470 was acquired in 1968 by Dwight Smith, and in 1974 joined the Conway Scenic Railroad and renumbered as #47. It was renumbered back to #7470 in the mid 1980's. Today, #7470 is used primarily to power the Conway-bound Valley Trains during the autumn seasons, as well as special excursions such as Steam in the Snow. It has also pulled the Notch Train on special occasions, recently as of 2011.
7470 is currently out of service for its rebuild and overhaul work as of January 15, 2015. Before then, it ran one more Steam in the Snow event before its overhaul became due. 7470 will return to active service in the spring of 2019.
