Data from the CofGA 1905 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange. Works numbers were 3837 in October 1887, 3840, 3844 in November, 3874-3875, 3877-3878, 3886-3888 in December, 3945-3947, 3951 in May 1888, 3954 in June
Firebox heating surface that included 25.15 sq ft (2.34 sq m) 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). Because both the tube and total heating surface areas were changed in ink such that the new values are uncertain, the evaporative heating surface is an estimate based on his own calculation of tube heating surface area and the addition of the 119 sq ft of firebox area.
Data from the CofGA 1905 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange. (Thanks to Samuel Smith for his 26 October 2022 email querying the language reporting the arch tube area, which led to a rewrite to clarfy.) Works numbers were 725-726 in November 1889, 727-730 in December, 734 in
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. Locobase notes that the 1905 diagram shows the firebox heating surface as including 25.15 sq ft (2.34 sq m) of arch tubes
The builder supplied 20 slightly larger locomotives with the same power dimensions a year before; see Locobase 7922.
Data from the CofGA 1905 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange. Works numbers were 657-664 in September 1888, 665-666 in October, 678-683 in December, and 684-687 in January 1889.
Firebox heating surface that included 25.15 sq ft of arch tubes.
This was the earlier, larger batch of Moguls that the C of Ga procured from Scranton, Pa's Alco predecessor. A later batch of 10 with a slightly smaller boiler and grate would follow within the year; see Locobase 7921.
By 1927, when the 1473 was the only Mogul left on the Central of Georgia'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).
1471 was sold to Georgia Car & Locomotive, which renumbered it 356, refurbished it, and sold it to Cuba Cane Sugar Corporation as their #1.
