The Samson is an English-built railroad steam locomotive made in 1838 that ran on the Albion Mines Railway in Nova Scotia, Canada. It is preserved at the Nova Scotia Museum of Industry in Stellarton, Nova Scotia and is the oldest locomotive in Canada.

A shell or flued boiler is an early and relatively simple form of boiler used to make steam, usually for the purpose of driving a steam engine. The design marked a transitional stage in boiler development, between the early haystack boilers and the later multi-tube fire-tube boilers. A flued boiler is characterized by a large cylindrical boiler shell forming a tank of water, traversed by one or more large flues containing the furnace. These boilers appeared around the start of the 19th century and some forms remain in service today. Although mostly used for static steam plants, some were used in early steam vehicles, railway locomotives and ships.
