Akron, Canton & Youngstown 2-8-0 "Consolidation" Locomotives in the USA


Class Details by Steve Llanso of Sweat House Media

Class M (Locobase 7617)

Data from the AC&Y 7 -1942 locomotive diagram book supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange. See also DeGolyer, Vol 71, pp. 1-19. Works numbers were 55566-55567 in August 1922 and 56848-56850 in August 1923.

Among the few road engines the AC & Y bought new were these five Consolidations. The first two had 42 sq ft (3.9 sq m) of thermic syphons, 10" (254 mm) piston valves.

The second batch were slightly heavier and had 4 more square feet of thermic syphons, but otherwise identical except for detail differences. One of the latter was the lengthening of the cab by eight inches (203 mm), four in front, four in back.
