    The Pennsylvania.  This was a last-gasp to try to save 
steam. Built in 1944.  It had two turbines, one for forward 
and another smaller one for reverse.  I have to look it up 
but think the turbines were built by General Electric.  The 
locomotive was a failure, it was to heavy and turbines do 
not have good slow speed traction. This is the only 686 
locomotive ever built.  The 6 wheel leading and trailing 
trucks were made necessary because of the weight and 
supposedly war-time shortages of metals that would have made 
four wheel trucks possible.
    AFAIK, this was the only direct-drive turbine built in 
the U.S. but there were others built experimentally in 
Europe.  There were also some turbine-electric locomotives 
attempted. One built by General Electric in 1938 for the 
Union Pacific, another built about 1947 by Baldwin for the 
C&O and also another railroad (forgot which).  The N&W also 
tried a turbine-electric which was more successful than the 
C&O one but none of them could compete with 
diesel-electrics.
