The Florida land boom in the 1920s dramaticly increased the FEC's passenger business and it reacted by improving the railroad, buying more motive power and more cars. Between 1924 and 1926 it bought 125 new locomotives most of which were "Mountain" type locomotives.
The first time FEC bought "Mountains" was in 1923, with fifteen from the American Locomotive Company. These locomotives were assigned road numbers 301 through 315 and had 25 x 28 cylinders, 68" drivers, a 200 psi boiler pressure, a tractive effort of 43,100 lbs and a total weight of 278,000 pounds.
A second batch of 52 (road numbers 401 through 452) came from ALCO in 1924 through 1926. This group of locomotives had 26 x 28 cylinders, 73" drivers, a 200 psi boiler pressure, a tractive effort of 44,100 lbs and a weight as shown in the chart below.
A last group of 23 came from ALCO in 1926. These "Mountains" were assigned road numbers 801 through 823 and had 28 x 30 cylinders, 69" drivers, a boiler pressure of 210 psi, a tractive effort of 60,800 lbs and weighed 356,000 pounds.
A hurricane in 1926 and the stock market crash killed the land boom. FEC's revenue fell drastically and it had to declare bankruptcy in 1931.
The FEC ultimately sold 50 of the 90 "Mountains" in its fleet. In 1936 it sold two (road numbers 417 and 420) to the Atlanta, Birmingham & Coast, five (road numbers 401, 409, 411, 413 and 416) to the St. Louis Southwestern, ten (road numbers 403 through 408, 410, 412, 414 and 415) to the Western Pacific and three (road numbers 402, 418 and 419) to the Western Railway of Alabama. In 1941, 1945 and 1948 it sold thirty of its 4-8-2s to the National Railways of Mexico. The 1941 sale included road numbers 304, 305, 307 through 309, and 311 through 315. In 1945, numbers 429, 433, 434 and 441 through 452 went to Mexico. The last group sold to NdeM included 421, 422, and 425 through 427.
|Road Numbers||Locomotive Weight|
|301 - 315||287,000 lbs|
|401 - 417||313,000 lbs|
|420 - 432||318,500 lbs|
|433 - 422||322,000 lbs|
|443 - 452||321,500 lbs|
|801 - 823||356,000 lbs|
One of the lightest Mountain designs to be built, but had an impressive percentage of superheater area and firebox heating surface area as well as generously scaled 14" (356 mm) piston valves. The latter included 74 sq ft (6.87 sq m) in thermic syphons.
They were retired over a thirteen-year period from 1941-1954. 310 was lost in a wreck in February 1945 at Wewahotee, Fla.
Many were sold in December 1941 to the National Railways of Mexico. Five fell in the TR-1 class (ex-304-305, 308, 311-312, 315) and were numbered 3200-3205. Ex-307 (sold to the NdeM in October 1948), 309, 313-314 were classified TR-2 and renumbered 3206-3209.
Firebox heating surface includes 60 sq ft of thermic syphons.
Although bigger than the earlier 300 series (Locobase 1347)and graced with more cylinder volume thanks to a one-inch (25.4 mm) increase in diameter,, these engines used larger grates to heat more tubes of greater length as well as slightly larger fireboxes. Superheater area and firebox heating surface kept pace. Contributing to the latter were 60 sq ft (5.75 sq m) of thermic syphons. Their larger cylinders turned taller drivers, which nearly canceled out any tractive effort gain, but allowed them to run at higher speeds.
(See the Central Vermont U-1s -- Locobase 7102 -- for an essentially identical design.)
The FEC engines were retired over a 19-year period from 1936 to 1955, when they were sold to other railroads. Western Railway of Alabama bought the first to be sold in June 1936, Grouped as WRA class M, 402 was renumbered 185. Sold a month later, the 419-420 took 187 and 186, respectively.
In that same month (July 1937), the Atlanta, Birmingham & Coast bought 417 and 420 as class M-1 and renumbered them 351 and 372 while the Cotton Belt (St Louis Southwestern) took delivery of the ex-401, 409, 411, 413 as their class L-0 and gave them road numbers 676-679.
Western Pacific bought ten of the class in August 1936. 403-408, 410, 412, 414-415 went into WP service as their 171-180.
Almost a decade later, twenty went to the National Railways of Mexico in September 1945 (2), as their class TR-3 (road numbers 3300-3319). 433-434 were sold in September, 441-452 went in the next month, and the class finished with ex-425-427 and 429 in October 1948.
Two were lost in wrecks. 431 was destroyed at Milepost 358 in December 1947 while 432 was totalled on the Seaboard Air Line in October 1949.
Firebox heating surface included 68 sq ft (6.3 sq m) of thermic syphons. Based on the USRA heavy Mountain design, these were the last new steem locomotives bought by the FEC. They were substantially bigger and heavier than either of the two earlier 4-8-2 class (Locobases 1347-1348). Superheating surface area as a percentage of combined heating surface increased still more while smaller drivers raised tractive effort.
All continued to serve the FEC into the 1950s except for 802, which was destroyed in October 1940 by a boiler explosion. 815 suffered a similar fate in April 1951 at Delray. 813 was lost in a rear-end collision in May 1952. The others were sold for scrap to Florida Iron and Metal Company in October-December 1954.
