Data from John H White, A History of the American Locomotive: Its Development, 1830-1880 (Dover Press, 1979), pp. 383-391. Works number was 59 in February 1857.
Another of William Mason's highly regarded 4-4-0s. Boreas, one of the engines of this class ran on the T & I (later part of the Wabash system) until around 1890.
NB: The direct heating surface (including the firebox heating surface) is an estimate calculated by subtracting the calculated tube heating surface from the reported total evaporative heating surface.
