The New Brunswick station

 The five transformers which take the current from the generator and step it up
in voltage sufficiently high to charge condensers.  They carry the full power of
the station whenever signals are being sent.  The type of bus bar construction
shown is typical of the work throughout.   All parts are accessible and so arranged
that any transformer may be quickly cut out and a spare unit substituted without
shutting off the current.
