The Pennsylvania Railroad's S2 class was a steam turbine locomotive designed and built in a collaborative effort by Baldwin Locomotive Works and Westinghouse Electric & Manufacturing Company, as an attempt to prolong the dominance of the steam locomotive by adapting technology that had been widely accepted in the marine industry. One was built, #6200, delivered in September 1944. The S2 was the sole example of the 6-8-6 wheel arrangement in the Whyte notation, with a six-wheel leading truck, eight driving wheels, and a six-wheel trailing truck. The S2 used a direct-drive steam turbine provided by the Westinghouse Electric & Manufacturing Company, geared to the center pair of axles with the outer two axles connected by side rods; the fixed gear ratio was 18.5:1. Such design was to prevent e

rdfs:comment	Die S2 der Pennsylvania Railroad war die leistungsfähigste je gebaute Dampfturbinenlokomotive. Die Lokomotive mit der Betriebsnummer 6200 wurde 1944 von den Baldwin Locomotive Works hergestellt und bereits 1953 wieder verschrottet.
