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. 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.
