Jonesboro, Lake City & Eastern / St Louis-San Francisco / Fort Worth & Rio Grande 2-6-0 "Mogul" Type Locomotives

Class 300 (Locobase 4148)

http://www.frisco.org/fmig/newsletters/fmig21/fmig21h.htm is the source for this data. These small Moguls were scrapped in 1915.

Class 304 (Locobase 4143)

http://www.frisco.org/fmig/newsletters/fmig21/fmig21h.htm is the source for this data.

Baldwin's works numbers for this set of straight-boilered Moguls included 8230-31 and 8233 in 1886 and 8777-78, 8782-84, 8786-87, 8790, 8794-95 in 1887. They were immediately followed by 20 wagon-top engines; see Locobase 4144.

Class 317 (Locobase 4144)

http://www.frisco.org/fmig/newsletters/fmig21/fmig21h.htm is the source for this data. This batch of 20 followed the 304s (Locobase 4143) , but had a slightly larger firebox created by the adoption of a wagon-top boiler.

Works numbers ran nearly consecutively beginning at 9319, 9321-22, 9325-31, followed by 9359, 9364-65, 9368, 9370-74, and ending with 9377. Most were scrapped in 1915, although a few hung on into the 1920s.

Class 32 / 72 (Locobase 6778)

Data from SL&SF All Time Loco Diagrams HS Pub supplied in May 2005 by Allen Stanley from his extensive collection. Works numbers wer 39038-39039 in January 1913 and 43278-

43279 in May 1916.

The JLC & E was an Arkansas short line built to serve the lumber country in the northeast part of the state. Finished in 1901, it operated independently until 1924 when the Frisco bought the road. This class of Moguls were part of the spoils and were renumbered 72-74. Ex-33 never went to the Frisco because it was sold to Southern Iron & Equipment in 1925.

The other were retained in service for years. 72 was "dismissed from service" in October 1937 at Chaffee, Missouri. 73-74 carried on through World War Two on the Frisco, but were sold in September 1945 to the Delta Valley & Southern, an Arkansas shortline that connected Delpro to Elkins. They may have served the DV & S only for a short while as the railroad abandoned much of its line in 1947.

Class 337 (Locobase 8589)

Data from SL&SF All Time Loco Diagrams HS Pub and SL&SF 7 - 1908 Description of All Equipment supplied in May 2005 by Allen Stanley from his extensive collection.

This class of Moguls all came to the Frisco in 1892-1894, arriving in drips and drabs. The earliest works number was 12576 in March 1892, the latest 13898 in January 1894. Compared to a class of Baldwin 2-6-0s delivered 4 years earlier, these had more tubes and a bigger boiler overall, but the grate area remained about the same.

Most were "dismissed" from the Frisco in the late 1920s. 346 went to the New Iberia & Northern Railroad in May 1916 as their #42, 345 was sold to the Cassville & Exeter Railway in Cassville, MO in June 1935

Class 354 (Locobase 4145)

http://www.frisco.org/fmig/newsletters/fmig21/fmig21h.htm is the source for this data. Larger heating surface than the earlier Frisco Baldwins, but using a smaller grate. The longer wheelbase spread out the greater weight.

By the time these went to the Santa Fe in 1937 (Locobase 804), their boilers had given up 28 tubes, but gained a larger firebox.

Class 359 (Locobase 4146)

http://www.frisco.org/fmig/newsletters/fmig21/fmig21h.htm is the source for this data. A repeat order for the Fort Worth & RG (can't identify) with a larger boiler, but still the small grate and smaller cylinders. 361-362 were heavier at 106,500 lb on the drivers and 125,500 lb total engine weight.

Class 363 (Locobase 4147)

http://www.frisco.org/fmig/newsletters/fmig21/fmig21h.htm is the source for this data. Originally ordered for the St Louis, Memphis & Southeastern, these two engines (works # 8410, 8408, respectively) were taken into the Frisco fold in 1907.

Compared to other Frisco moguls, these engines had relatively large grates and a considerable amount of firebox heating surface. They only lasted a few years in Frisco service, going to the ferro-knacker's yard in June 1916 and July 1915, respectively.

Class 73 (Locobase 8549)

Data from SL&SF All Time Loco Diagrams HS Pub supplied in May 2005 by Allen Stanley from his extensive collection. Works numbers were 43278-43279 in May 1916.

Four years after purchasing the Mogul shown on Locobase 6778, the JLC & E went back to Baldwin for two more, this time with superheaters. Alas, the diagram doesn't show the superheater area, but it does depict the number of flues and their diameter and length. Based on that evidence, Locobase estimates the superheater area to have been around 190 sq ft.

Both were sold off in September 1945, the 74 going to the scrapper (Merritt, Chapman, Scott Corp or Memphis) and 73 to the Delta Valley & Southern Railway.
