The Boston & Albany's class K14g 4-6-2s were erected by American Locomotive Company in 1913. They had a driver diameter of 72 inches and 26x26-inch cylinders, and sustained 190 pounds per square inch of steam pressure. With these dimensions they developed a nominal tractive effort of 39,420 pounds, and their locomotive weight was 275,600 pounds. Pacific No. 586 poses here with its local passenger train, at an unknown location on the B&A sometime in the early 1930s.
