For instance, the "B" referred to the unit having a B-B truck setup (two
axles per truck) while the "39" referred to it having 3,900 horsepower.
The "8" reference simply meant it was a model of GE's "Dash 8" series.
The locomotive used GE's standard 4-cycle, 16-cylinder FDL prime mover featuring its model 752AF traction motors,
which by the 1980s had become one of its major marketing features. As a
four-axle "Dash 8" locomotive the model could produce 68,500 pounds of
starting tractive effort and 68,000 pounds continuous (about the same as
the later B40-8W). Of note, the design was one of GE's final cataloged
models not to have the later FRA-mandated Safety Cab as a standard
feature. The Norfolk Southern, for instance, held out on having its
locomotives include this cab until ordered to do so.
Perhaps the most noticeable difference in later B39-8s, from its earlier
design and also the B32-8, was the change to the rear radiator air
intakes which were now canted (i.e., angled) instead of being flush with
the carbody. Nearly all future GE models featured this angular design
to their air intakes, which carried on to this day. Production of the
design began in early 1984 and only two Class Is purchased the model, AT&SF (3) and Southern Pacific (40). Most, 102 (listed as a B39-8E),
were purchased by Locomotive Management Services, which as their name
suggests, leases out motive power to railroads. With the one GE
demonstrator built overall 146 B39-8s were constructed. Today, numerous regionals and short lines still operate the
model, and they can also be found in Canada and South America. Some of
the lines that use the locomotive include the Providence & Worcester; Montreal, Maine & Atlantic; Ferrocaril Central Andino
(Peru); and the Nashville & Eastern.

For more reading about General Electric diesel locomotives there are a few books written by noted historian Brian Solomon worth mentioning which highlight the history and background of the company. First, is GE Locomotives, a title that provides a thorough history of its locomotive line from the earliest days of building electrics and experimental diesels to the latest models built through the early 2000s. Second, is GE And EMD Locomotives: The Illustrated History, which generally highlights the history of both company's designs. As with virtually all of Mr. Solomon's you can expect well-written titles with large, crisp, and sharp photographs featured throughout.
