One of the lightest Mountain designs to be built. Retired over a 13-year period from 1941-1954. Many sold to the National Railways of Mexico.
Firebox heating surface includes 60 sq ft of thermic syphons.
Although bigger than the earlier 300 series, these engines still weren't over-endowed with power. (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, principally the National Railways of Mexico. (Cotton Belt, Western Pacific, the Atlantic Coast Line, and the Western Railway of Alabama also picked up 3 ex-FECs (builder's numbers 65749, 65765, and 65766).
Firebox heating surface included 68 sq ft of thermic syphons. Based on the USRA heavy Mountain design; Alco builders numbers 66811-66833.
Last new locomotives bought by the FEC and ran until 1951-1955.
