Canadian National 7470 is a preserved CN O-18-a 0-6-0 steam locomotive at Conway Scenic Railroad in North Conway, New Hampshire.
The locomotive was built by the Grand Trunk Railway at Pointe-Saint-Charles in 1921. The Grand Trunk classified the switcher as F9 Class and numbered it as 1795. When the Canadian National Railway absorbed the Grand Trunk in 1923, they reclassified it as an O-18-a and renumbered it as 7470.
After retirement, 7470 was spared scrapping by being sold to Canada Dominion Sugar, where it spent some additional years as a switcher. In 1964, it was purchased by the Ontario government for a transportation museum that never came to fruition, and in 1968 it was sold to Dwight Smith.
Dwight Smith was working on founding the Conway Scenic Railroad, which opened in 1974. Locomotive 7470 was renumbered as Conway Scenic 47 and was the new railroad's only locomotive in its earliest years. The old number 7470 and Canadian National paint scheme were restored in 1988 according to Railfan & Railroad magazine.
Today, 7470 currently pulls the Conway Valley Train in the September, October and January seasons only, where it makes special event runs such as Railfan's Weekend in mid-September, fall events in mid-October, and Steam in the Snow events in January where it is hosted by the Mass Bay Railroad Enthusiasts. It used to run during summer months as well, but ended in 2007, excluding special excursions. 7470 has also pulled the Notch Train on rare occasions for special events, once in 2007 and again in 2011.
In July 2014, it was announced that 7470 was going to be coming out of service due to a major federally mandated inspection and overhaul. 7470 ran its last train on January 3, 2015, and its overhaul work began the following day. It has been out of service since that time and is planned to return to service again in the summer of 2018.
7470 made its first ever film appearance in the 1972 Paramount Pictures film A Separate Peace, lettered as Boston & Maine 47.
