Canadian National 1551 is a H-6-g class "Ten-wheeler" type steam locomotive, built in 1912 by the Montreal Locomotive Works (MLW) for the Canadian Northern Railway (CNoR). It is preserved at the Age of Steam Roundhouse in Sugarcreek, Ohio.
The locomotive was built in April 1912 by the Montreal Locomotive Works (MLW) as Canadian Northern Railway No. 1354. It kept that number after the CNoR merged into the Canadian National Railway (CN), but when diesels arrived, it was renumbered as No. 1551 in October 1956. The locomotive hauled heavy freight and passenger trains throughout Ontario and Montreal until it was retired from revenue service in 1958.
In September 1961, No. 1551 was purchased by F. Nelson Blount, who sent it for display at the Edaville Railroad in Massachusetts, United States, then added it to his collection at Steamtown, U.S.A, in Bellows Falls, Vermont. After Blount's death in 1967, the collection was moved to Scranton, Pennsylvania.
In January 1986, the locomotive was purchased by Jerry Jacobson in a trade for Jackson Iron & Steel Company No. 3. Over the next two years, Jacobson and his crew restored the engine to operating condition, completing the work in October 1988. For the next 15 years, No. 1551 hauled excursion trains for Jacobson's Ohio Central Railroad System (OHCR) and occasionally other lines. One of its engineers described the locomotive as an easy engine to work.
In September 1997, No. 1551 operated for the OC's Steam Fest '97 event alongside the railroad's other steam locomotive, Canadian Pacific 1293. T-1 Reading 2100 also participated in the event but was the only locomotive not to be fired up for the weekend occasion.
In 2003, the locomotive was taken out of service to undergo major repairs. In 2011, the engine, along with the rest of Jacobson's steam locomotive collection, were moved into the new Age of Steam Roundhouse in Sugarcreek, Ohio, United States. Today, No. 1551 is on static display inside the roundhouse, where it awaits a planned major rebuild and return to service.
