Central of Georgia / Covington & Macon / Savannah & Western 4-4-0 "American" Locomotives of the USA


Class Details by Steve Llanso of Sweat House Media

Class 1233 (Locobase 7923)

Data from CofGa 1905 and CofGa 11 - 1927 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection. See also DeGolyer, Volume 10, p. 264. Works numbers were 5891-5892, 5958-5959 in December 1881. Boiiler pressure is an estimate.

The original diagram shows five locomotives with these specifications (dimensions that made them the smallest 4-4-0s in the 1905 diagram book), but Locobase feels comfortable in identifying only the following:

Works 5891 was delivered as Marietta and received number 110 in 1884. Renumbered 1526 and later 1530, it was retired in November 1918.

5892 was delivered as Madison and numbered 109 in 1884. It was later renumbered 1233, then 1501, and finally sold to the BR & L.

5958 came into service as Clinton and was numbered 112 in 1884. After being renumbered 1528, it was out of service by 1912.

5959 was named Flint and numbered 111 in 1884. Renumbered 1527 and 1535, it was retired by 1925.


Class 1558 (Locobase 7927)

Data from CofGa 1905 and CofGa 11 - 1927 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection. Works numbers were 667-672 in November 1888.

These Dickson engines (works# 667-672) fell into the middle of the range of American Eight-wheelers (Americans?) of the period in most dimensions. One noticeable difference was the relatively low boiler pressure (at least as shown in 1925).


Class 1564 (Locobase 7928)

Data from CofGa 1905 and CofGa 11 - 1927 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection. Works numbers were 2072-2073 in 1889.

Relatively small, short boiler on these Rhode Island locomotives.


Class 1567 (Locobase 7929)

Data from CofGa 1905 and CofGa 11 - 1927 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection. See also DeGolyer, Volume 16, p. 11. Works numbers were 10848 and 10859 in May 1890.

As the Eighties faded into the Nineties, Baldwin supplied this pair of Eight-wheelers, which were a bit bigger than earlier S&W engines. Even so, they sat squarely in the third quartile of 4-4-0s delivered to US railroads during the period. They were delivered with 3" tires and, as often happened, were later fitted with 3 1/2" tires that increased driver diameter to 63". The Central of Georgia also increased boiler pressure to 150 psi (10.34 bar), which raised calculated tractive effort to 14,265 lb (63.45 kN)

As noted in Locobase 7903, both the S&W and the Central of Georgia went into receivership in the early 1890s. When affairs had been settled, the C of Ga name survived and the S&W assets were absorbed. These two saw out their careers on the C of Ga, the 337 (as then numbered) being scrapped in December 1928 and the 336 in March 1932.


Class 1575 (Locobase 7934)

Data from CofGa 1905 and CofGa 11 - 1927 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection. Works numbers were 2074-2076 in 1889.

Three of the Rhode Island locomotives to serve the C of Ga arrived in 1889; two (works #2075-2076) had 63" drivers, the other (works #2074 shown in the specs) stood on 69" drivers.

Later in their careers, 18 sq ft of arch tubes contributed to the engines' firebox heating surface as is shown in the specs.

346 was scrapped in November 1934 as part of a general clearing out of old Central of Georgia Eight-wheelers. 344 was scrapped in December 1935 while 345 remained on the roster until scrapped in May 1939.


Class 1578 (Locobase 7935)

Data from CofGa 12 - 1925 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection. Works numbers ran 11994, 11995, 11998, 12001 in June 1891 and 12009 in July.

This class of Baldwin Eight-wheelers had slender, high-pitched boilers that nevertheless had the firebox dropped between the driving axles. The steam dome sat ahead of the firebox and over the front driving axle and the sand dome halfway between the steam dome and the inversely tapered stack. The first two had 69" drivers, but only the first had its boiler pressure set at 155 psi. 1586's 168 psi setting and 63" drivers yielded 17,590 lb tractive effort.

1585, which had the same specifications but 170 psi in the boiler and 69" drivers (16,524 lb TE) and 1586 (63" drivers) arrived in 1892 and had the later pair of works numbers 13086 and 13086.


Class 1592 (Locobase 7936)

Data from CofGa 11 - 1904 Locomotive Diagrams supplied in August 2013 by Allen Stanley from his extensive Raildata collection. Works number was 12864 in August 1892.

Locobase 7935 shows the pair of Vauclain compounds that had two sets of 11 3/4" (298 mm) HP and 19" (483 mm) LP cylinders supplied steam through common piston valves of 9" (179 mm) diameter. (See limited specs at DeGolyer, Volume 17, p. 225.) Like that class, this engine was soon rebuilt as a simple-expansion engine as shown in the specs.

At some later date, the Central of Georgia fitted a new boiler and firebox that increased heating surface areas to 1,426 sq ft (132.48 sq m) in the tubes, 131 sq ft (12.17 sq m) in the firebox with a supplemental 18 sq ft (1.67 sq m) in arch tubes for a total of 1,575 sq ft (146.32 sq m) total evaporative heating surface area. The grate area also grew to measure 17.6 sq ft (1.64 sq m).

All three ex-Vauclains were scrapped in November 1934.


Class 1593 (Locobase 12049)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 18, p 103. Works numbers were 13085-13086 in December 1892.

This pair of Eight-wheelers was delivered with the relatively small version of the Vauclain compound design of two sets of cylinders, each one consisting of one HP and one LP cylinder served by a common 9 3/4" (248 mm) piston valve.

As with most such compounds, these were converted to simple-expansion locomotives within a decade; see Locobase 16166.


Class 1593 - simpled (Locobase 16166)

Data from CofGa 11 - 1904 Locomotive Diagram books supplied in August 2013 by Allen Stanley from his extensive Raildata collection.

This pair of Eight-wheelers was delivered with the relatively small version of the Vauclain compound design (Locobase 12049). Like most such North American compounds, this pair was converted to simple expansion before the decade was out.

As simple-expansion locomotives, they served until scrapped in November 1934.


Class 200/1568/1571 (Locobase 7933)

Data from DeGolyer, Volume 16, p. 88. See also CofGa 1905 and CofGa 11 - 1927 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection. Works numbers were 11078-11080, 11083 in July 1890.

Four of the Eight-wheelers delivered by Baldwin in 1890 differed from those described in Locobase 7929 in having 1" greater diameter cylinders.


Class Alexander Brown (Locobase 7926)

Data from CofGa 1905 and CofGa 11 - 1927 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection. See also DeGolyer, Volume 15, p. 49. Works numbers were 9894 (Alexander Brown #3) and 9897 (William G Bowdoin #5) in March 1889.

Like many of the other Central of Georgia precessors, this railroad underwent several name changes with their associated renumberings. The C&M was built to connect Macon and Athens, Ga, a distance of 105 miles. Not long after the C & M took delivery, the railroad failed and was reorganized as the Macon & Northern in 1891. Four years later, the Central of Georgia purchased the M & N on 31 October 1895.

The C of Ga renumbered these two Eight-wheelers four times. 322 was scrapped in December 1928 while 322 remained until March 1932.


Class E (Locobase 7925)

Data from CofGa 1905 and CofGa 11 - 1927 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection. See also DeGolyer, Volume 11, p. 245. Works numbers were 6396, 6398 in September 1882; 6415, 6419 in October; 6545-6546 in December; 6930,and 6933, 6965-6966 in September 1883; 7009 in October; and 7010, 7017-7018 in November.

Early Eighties Eight-wheelers from Baldwin that had state names: Indiana, Ohio, Michigan, Iowa, Nebraska, Wisconsin, Arizona, Dakota, Idaho, Kansas, Colorado, Montana, Wyoming, Maine. They were delivered with 179 2" tubes and 57" drivers. By 1896, all had been converted to 63" drivers.

They enjoyed a long enough life to appear in the 1925 & 1927 Locomotive diagrams. By then the diagrams showed 14.7 sq ft of arch tubes as part of the firebox heating surface.

1532 (ex-Michigan) was sold to the Shearwood Railway of Brooklet, Ga around 1909, when the Shearwood Lumber Company opened the line. It had 8.3 miles in 1914 and 38 miles in 1926. It was abandoned in July 1937, by which time the ex-1532 was likely long since scrapped.

305 (ex--1536, ex-Arizona was sold in February 1931 to Alabama Fuel & Iron. Ex-1538, ex-Idaho was sold to the Valdosta Southern as their 26.

For some reason, Colorado, #127, took 1234 when it was renumbered, unlike the rest of the class. It later went to the Savannah & Atlanta as their 12. The S&A later sold the engine to Georgia Car & Locomotive, which found a buyer in the Bamberg (South Carolina), Ehrhardt & Walterboro. The BE&W gave the engine #163. It opened in 1914 with 14 miles of line and two locomotives. It was abandoned in November 1937.


Class Empire State/1554 (Locobase 7924)

Data from CofGa 1905 and CofGa 11 - 1927 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection. See also DeGolyer, Volume 13, p. 65. Baldwin works numbers were 8001-8002 in June 1886 and 8129 in September.

The C&M ordered six engines in 1885, but almost immediatedly sent #3 (Locobase 15948) on to the Palmetto. Two more were sold before delivery to the Enterprise Construction Company in Arkansas as their 1 & 2; see Locobase 8645.

By 1925, the C of Georgia diagram was showing 14.7 sq ft of arch tubes in the firebox, which increased direct heating surface to 116.7 sq ft.
