Central of Georgia 2-6-0 "Mogul" Type Locomotives

Class 1400 (Locobase 7905)

Data from the CofGA 1905 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive collection. Firebox heating surface that included 25.15 sq ft of arch tubes.

Locobase can tell that these Moguls were delivered in differing batches, possibly as part of a larger order that included Dickson-built locomotives (Locobase 7921).

Class 1410 (Locobase 7921)

Data from the CofGA 1905 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive collection. Firebox heating surface that included 25.15 sq ft of arch tubes.

Compared to the Rogers Moguls shown in Locobase 7904, these Dicksons were heavier and had a significantly larger, but still narrow, grate. On the other hand, the boiler profile shows a short course with steam dome over the firebox, noticeable taper to a long first course. The builder supplied slightly larger locomotives some years later; see Locobase 7922.

Class 1460 (Locobase 7922)

Data from the CofGA 1905 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive collection. Firebox heating surface that included 25.15 sq ft of arch tubes.

This relatively numerous class of locomotives continued the same profile and power dimensions as the earlier Dicksons shown in Locobase 7921. The boiler had a few more tubes that were 6" longer, the grate area continued to grow, and the adhesion weight increased as well. Otherwise, the design had no major tweaks.

By 1927, when the 1473 was the only Mogul left on the G of G's roster, the original firebox area had been augmented by 16.75 sq ft of arch tubes (or the 1905 diagram hadn't bothered to note arch tubes -- an omission Locobase has seen in other diagrams).
