1919 Pennsylvania Railroad
NO. 3700 2-8-8-0
ONE OF the most interesting articulated locomotives ever built
was this single-expansion type, the most powerful steam engine
the Pennsylvania has ever had. The drawbar pull was too great
to handle trains not fully equipped with the latest MCB couplers,
and this locomotive was used in pushing service on the Allegheny
Mountain grades, where it performed very well. No others of its
type were ever built, but valuable data was obtained during its
ten years of service.
