Florida East Coast 4-6-2 "Pacific" Type Locomotives

Class Details by Steve Llanso

Class 151 - superheated (Locobase 3138)

Data from FEC 1926 locomotive diagram book supplied in May 2005 by Allen Stanley from his extensive collection.

Relatively lightweight Pacific class that capped the Florida East Coast's acquisition of 87 4-6-2s of similar dimension from 1907-1922. Fitted with 11" (279 mm) piston valves. 141-157 were superheated when produced in 1920-1922; earlier locomotives, procured in 1910-1917, were all superheated to the same standard.

One of these oil burners operated out on Henry Flagler's Florida Keys viaduct and just made it off the exposed line before the 1938 Hurricane swept the entire line away.

Most of these engines were sold to other railroads in the late 30s-early 40s.

Drury's full list of FEC transfers (Drury, 1993, pp. 185-186) can be summarized as follows:

Twelve of the AB & C engines later were renumbered by the Atlantic Coast Line, three of the AB & Cs (76, 78, and 85) went to the Appalachicola Northern as 301, 300, and 302, respectively, both of the AN's acquistions wound up as Kansas City, Mexico & Orient engines 152-153, and one of the A & St AB locomotives was sold to the CN & L as their 154.

Alco-Schenectady works numbers for some in the class included:

50143-50147 (road 98-102) in 1911

53892-53903 (road 103-114) in 1911

60167-60171 in 1920

1922

Class 65 (Locobase 5716)

Data from FEC 1926 locomotive diagram book supplied in May 2005 by Allen Stanley from his extensive collection.

The first in a long line of FEC Pacifics over a 15-year period. The American Engineer & Railroad Journal (February 1908) noted that using the Walschaerts valve motion on the Pacific wheel arrangement offered difficulties because the front driving axle was so close to the cylinder. The article described Schenectady's solution was "one of the simplest and the best".

These batches - delivered between 1907 and 1910 - were followed by several dozen more. Other than an increase in cylinder diameter to 22" and the introduction of superheating, all of the locomotives were very similar in size and weight. (See Locobase 11033 for the superheated version of this class and Locobase 3138 for the 22" version.)

Class 65 - superheated (Locobase 11033)

Data from FEC 1926 locomotive diagram book supplied in May 2005 by Allen Stanley from his extensive collection.

As noted in 5716, this class originally was delivered with saturated-steam boilers. When the FEC superheated them, they retained the essentials of the original design in most cases and simply swapped tubes for flues. 5 engines (65, 80, 83, 90, 96) received 22" cylinders; their specs closely resembled those of the later class shown in Locobase 3138.

Most were scrapped in 1929-1930, although #69 and 88 went to the Georgia Northern in 1930 as their 106 and 108, 80 traveled to the Savannah & Atlanta in 1935 as their engine #750, and the 96 ended up as Georgia & Florida 500 in 1941.
