Data from IC 1955 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange.
As noted in Locobase 461, the 2-10-2 "Centrals"(2900 class) delivered by Lima in the early 1920s were deemed too slow for later traffic demands. So many were made over in a variety of wheel arrangements.
This entry shows the fifteen Decapods that resulted from mating sets of 2900 cylinder and frames with a 1500-class (2-8-2) boiler. Their firebox heating surface area included 31.6 sq ft (2.95 sq m) of arch tubes.
