Data from FEC 1926 locomotive diagram book supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange. (Thanks to Chris Hohl for his 20 January 2018 email overcoming a smudged diagram and using logic to calculate the tender's loaded weight and for reporting the correct driver diameter.) Works numbers were 28412-28421, 31240-31244, and 39047-39051 on locomotives that were delivered in 1904-1905.
These low-drivered Atlantics constituted a surprisingly numerous class. They were an odd breed -- the builder doesn't seem to have exploited the addition of a trailing axle to enlarge the grate or firebox area by much. Chris Hohl reported in his 20 January 2018 close reading of the FEC diagram that some of the class burned coal and trailed tenders carrying 9 1/2 tons (8.6 metric tons).
The class was disposed of between 1923-1930.
