Canadian National number 47 is an unusual Canadian locomotive. It is one of only two remaining CN 4-6-4T suburban tank locomotives (CN 49 is located at the Canadian Railway Museum in Delson, Quebec.) According to Wikipedia number 47 was built by the Montreal Locomotive Works in September 1914 for the Grand Trunk Railway as its class X10a, but became a CN locomotive after the creation of Canadian National Railways. Along with her sister locomotives, number 47 was based in Montreal and used exclusively in commuter service. Following retirement in 1959, it was sold to F. Nelson Blount to become part of his Steamtown collection. Number 47 was the first locomotive to run as a Steamtown excursion locomotive. It was intended the engine would become the primary excursion power. Having had a fresh overhaul in 1958 it was in top mechanical condition when acquired. However, it steamed for only 5 weeks in 1961 as the ICC (Interstate Commerce Commission) denied the boiler certification. The maintenance records had been lost in a roundhouse fire in Canada and it was not possible to verify the boiler condition to government inspectors without an expensive overhaul.
