Class C1 (Locobase 8465)

(Note: Official name for the Cotton Belt was St. Louis-Southwestern.)

Data from StL&SW 1 - 1932 Folio 725 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive collection.

170-184 were delivered from Rome in 1887 with 185-195 following in 1888.

The specifications represent the new boilers installed in the railroad's own Pine Bluff shops.

Compared to the Baldwin Ten-wheeler supplied a few years later (Locobase 8458), this was a bigger, more powerful locomotive. It had a more "modern" power unit that featured 9" piston valves actuated by Walschaert radial valve gear.

Class D2 (Locobase 3484)

These Moguls were used in transfer service and heavy switching around St. Louis. They arrived in 10-locomotive batches in 1900, 1901, and 1902. 330 was delayed by its appearance at St Louis's Louisiana Purchase Exposition in 1904.

306 later was fitted with one 27-sq ft thermic syphon in place of its 15 sq ft of arch tubes. When deductions for the 4 sacrificed boiler tubes were taken into account, the difference in total heating surface was 3 sq ft.

Class D3 (Locobase 8470)

Data from StL&SW 1 - 1932 Folio 725 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive collection.

Like the earlier D2s (Locobase 3834), these Moguls were used in transfer service and heavy switching around St. Louis. They were more frankly switchers, however, with their lower drivers, smaller boiler, and higher pressure. The combination meant more tractive effort at the expense of main-line endurance.

The first 5 were delivered in 1906, the last 5 in 1909. 340 later sacrificed one boiler tube to accept a single Nicholson thermic syphon that contributed 27.5 sq ft to firebox heating surface area. All told, direct heating surface area increased by 25.5 sq ft to 200.5 sq ft and overall heating surface grew 18.5 sq ft to 1,888.5 sq ft.

These switchers roamed the yards for several decades before retiring in 1945-1955.

Class E3 (Locobase 8471)

These may have been among the last Rogers locomotives to come out of Paterson before the firm's absorption by Alco. They were stubby with relatively capacious, high-pitched boilers and unevenly spaced driving axles (the front axle sat 7 ft away from the second, but the second lay only 5 ft from the third). The high-sided tenders carried water and oil enough for an extended tour of duty on transfer runs as well as switching.

The first of the class was retired relatively early in 1934 while the last carried on until 1956.

Class E4 (Locobase 8473)

These had relatively tall drivers for Cotton Belt Moguls and suggest a branch-line, local-freight mission for the class. The least of these served the StL-SW for almost 40 years and the last retired in 1950.

Class G1 (Locobase 8472)

Data from StL&SW 1 - 1932 Folio 725 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive collection.

Built as heavy switchers, these Moguls brought quite a bit of beef to the job. As their class ID indicates, they used the same power dimensions as the G1 Consolidations, but rode on 4 axles, not 5.

And in their final form as shown, they had a good percentage of superheater area and significantly more direct heating surface (as a percentage of EHS) than usual. The firebox held 15 sq ft of arch tubes and 2 Nicholson thermic syphons that contributed and additional 37 sq ft to firebox heating surface. The Walschaert valve gear operated 12" piston valves.

Although they were the last of the switching-transfer Moguls to enter service on the Cotton Belt, the entire class was retired in 1946. Locobase wonders if they were too much engine for another kind of service once they were supplanted in the heavy switcher role by diesels.
