They got one fact wrong:  Those rotary converters only provided
power for trains in Manhattan.  Rotary converter stations were
rarely as far apart as 10 miles when 750V DC power is used.  The
voltage drop on long DC feeders is too much.  Still, for the
Nazis, shutting down Grand Central Terminal and the Park Avenue
tunnel would have snarled a good part of the passenger service
(including troop trains) in the US.
