Boston & Maine 2-8-0 No. 2349 belonged the the railroad's K-7 class, but available data do not specify into which subclass she fell. American Locomotive's Schenectady Works built 70 engines in the group between 1905 and 1911, but the B&M rebuilt 66 of them with superheaters and reclassified them as K-5d or K-7b or c. Specifications for the group include 61-inch drivers, a boiler pressure of 200 p.s.i., and 20x30-inch cylinders. They weighed 176,600 pounds and mustered 33,443 pounds of tractive force. With 46½ square feet of grate area, they had 2046 square feet of evaporative heating surface and 437 square feet of superheating surface.
