Florida East Coast 4-6-0 "Ten-Wheeler" Locomotives in the USA


Class Details by Steve Llanso of Sweat House Media

Class 28 (Locobase 6675)

Data from FEC 1926 locomotive diagram book supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange. Works numbers were 4559-4563 in October 1897, 4920-4921 in December 1898, 5367-5368 in December 1899, and 5696-5700 in December 1900.

This was the first of two batches of Ten-wheelers that were distinguished primarily by builder, weight, and boiler pressure; see Locobase 6676 for the Baldwin-built variant. If the firebox shown in the 1926 diagram book was the one delivered in the late 1800s, they were wider and shallower than the traditional deep and narrow fireboxes produced by Baldwin..

Their careers on the FEC lasted only into the mid-1920s, although some lasted long enough to be sold into industrial service in the 1930s. Those latter engines were the first to be sold off. Three went to Kershaw Construction (31, 33-34) and another to Osceola Cypress (39). 30, 36, and 37 were scrapped early and the other five were sold to scrap dealers (four to Walker-Wallingford, one to Florida Iron Metal).


Class 40 (Locobase 6676)

Data from FEC 1926 locomotive diagram book supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange. See also DeGolyer, Volume 24, p. 167. Works numbers were 20032-20036 in February 1902.

These were the only Baldwins bought new by the FEC. Their Ten-wheeler design followed that of the twelve Schenectady locomotives shown in Locobase 6675. But their narrower, deeper fireboxes yielded considerably less grate and firebox heating surface area.

Three of the class were retired in 1925 (40, 42 in February and 44 in April) and 1930 (both in September). The 1925 engines went on to second careers for Drake Lumber Company, Sutton Brothers, and Donohoo Construction Company, respectively. The 1930 pair went straight to Walter-Wallingord Company for scrap.
