A few years ago, I read a book about power systems in Ontario.  There
were a few different frequencies, other than 25 & 60 Hz.  There were
even rotary converters (combination motor & alternator in one unit) to
change the frequency.  I seem to recall there was still one to convert
to 25 Hz for industrial users in the Buffalo area.
